Release D_12_6_5
1. Overview
The D_12_6_5 release of the Rational Environment is primarily a
maintenance release that:
* Fixes a large number of problems from previous releases,
enabling existing commands to work correctly. Some of these
fixes introduce new features (see section 6); other fixes
involve changed features (see section 7).
Efforts to fix problems have been focused in:
- System reliability.
Several problems that could cause the Environment to crash
have been fixed; and the Environment has been made more
robust in many (previously fatal) error conditions.
- The Ada compilation system.
In select cases, some changes may cause code that used to
compile to no longer compile. For details, see section 7.6.
* Changes the default value of the
R1000_Cg.Retain_Delta1_Compatibility library switch (from True
to False) so that, by default, the R1000 code generator takes
advantage of numerous features and bug fixes introduced in the
D_12_1_1 compiler. These features and bug fixes may cause the
code generator to emit code that is not compatible with
releases prior to D_12_1_1; see section 7.7.
* Introduces various new Environment interfaces, including:
- New procedures and functions in packages Access_List_Tools,
System_Maintenance, and Dfs; see sections 6.1, 6.2, and
6.3.
- A new world (!Machine.Login_Policy), in which you can place
subprograms and files that control login policies and
messages; see section 6.4.
- A new subsystem (!Tools.Telnet_Tools), which provides tools
for writing programs that use the Environment's networking
facilities; see section 6.5.
* Delivers the Documentation Tools, Rational X Interface (RXI),
and Rational Windows Interface (RWI) products with the
standard Environment. Product authorization tokens are no
longer required to use these products. See sections 3 and
7.14.
* Introduces three expanded and up-to-date volumes of the
Rational Environment Reference Manual:
- Volume 4: Session and Job Management (SJM)
RATIONAL May 1992 1\f
Rational Environment Release Information
- Volume 5: Library Management (LM)
- Volume 10: System Management Utilities (SMU)
New online help is also provided for each of the packages
described in these books; see section 8.
Note: This release information can be found in the
!Machine.Release.Release_Notes world in line-printer
(Environment_Release12_6_5_Lpt) and PostScript
(Environment_Release12_6_4_Ps) formats.
2. Supported Configurations and Upgrades
D_12_6_5 supports the following configurations of the R1000:

Before attempting to install new or changed CDF products or
customizations, see section 5.1.
#
Beginning with D_12_6_5, the most recent releases of
Documentation Tools, RXI, and RWI are delivered with the
Environment. Thus, compatibility with these products is no longer
an issue. For more information, see sections 6.6 and 7.14.
4. Upgrade Impact
The Environment can be upgraded from to D_12_6_5 without forcing
you to Archive.Save and Archive.Restore your applications. You
will not have to modify or recompile any of your own tools, with
the possible exception of:
* Tools written against the unit specifications listed in
"Impact of Specification Changes," below.
* Customizations of unit bodies listed in "Impact of
Implementation Changes," below.
The new declarations listed in section 6 are all installed
upward-compatibly and therefore have no impact on user-written
RATIONAL May 1992 5\f
Rational Environment Release Information
tools.
Rational does not provide tools for reverting to previous
releases of the Environment. You will be able to revert to the
previous release, however, if you make a complete backup of the
Environment, including the Diagnostic File System (DFS), before
you upgrade.
4.1. Impact of Specification Changes
The installation process for D_12_6_5 changes several Environment
specifications. The installation process attempts to make all
changes incrementally; however, if incremental changes fail, the
installation process overwrites the necessary specifications.
Overwriting these specifications will cause the demotion of any
customer-created tools written against them. The installation
process tries to recompile such tools automatically; however,
depending on the nature of the tools, some may require
modification before they can be recompiled. Units that cannot be
recompiled during installation are listed in the installation
log.
The unit specifications that are overwritten depend on the
release from which you are upgrading.
4.1.1. Upgrading from D_12_5_0
The following unit specifications are overwritten when you
upgrade from D_12_5_0 to D_12_6_5:
* !Commands.Library'Spec
* !Commands.System_Backup'Spec
* !Tools.Access_List_Tools'Spec
* !Tools.Code_Segment_Object_Editor'Spec
* !Tools.Library_Object_Editor'Spec
4.1.2. Upgrading from D_12_2_4
In addition to the unit specifications overwritten when upgrading
from D_12_5_0, upgrading from D_12_2_4 overwrites the following
unit specification:
* !Commands.Abbreviations.Print'Spec
* !Commands.Access_List'Spec
* !Commands.Archive'Spec
6 May 1992 RATIONAL\f
Release D_12_6_5
* !Commands.Queue'Spec
* !Commands.Remote_Passwords'Spec
* !Tools.Networking.Tcp_Ip_Boot'Spec
* !Tools.Networking.Transport'Spec
* !Tools.Networking.Transport_Defs'Spec
* !Tools.Networking.Transport_Name'Spec
Furthermore, the units in !Machine.Initialize@ are either demoted
or moved to other locations to accommodate the D_12_5_0
mechanisms for initializing an R1000; for complete details, see
Appendix A, "Guide to Machine Initialization," or the online
information in
!Machine.Initialization.Guide_To_Machine_Initialization.
If you are upgrading from D_12_2_4, you should also see the
release information for D_12_5_0; release information is located
online in !Machine.Release.Release_Notes.
4.1.3. Upgrading from D_12_1_1
In addition to the unit specifications overwritten when upgrading
from D_12_5_0 and D_12_2_4, upgrading from D_12_1_1 overwrites
the following unit specification:
* !Implementation.Work_Order_Implementation'Spec
If you are upgrading from D_12_1_1, you should also see the
release information for D_12_2_4 and D_12_5_0; release
information is located online in !Machine.Release.Release_Notes.
4.2. Impact of Implementation Changes
The installation process for D_12_6_5 overwrites one Environment
unit body (regardless of the release from which you are
upgrading):
* !Commands.Abbreviations.Print'Body
Because this body may contain user customizations, its contents
are saved in a text file in the same library as the overwritten
body. The name of the file is of the form Unit_Name_Vnn, where nn
is the unit's default version number. These customizations then
can be transferred to the new implementation.
5. Known Problems and Limitations
RATIONAL May 1992 7\f
Rational Environment Release Information
5.1. Problem Installing the Cross-Development Facility
The D_12_6_5 release of the Environment affects the installation
of any of Rational's family of Cross-Development Facility (CDF)
products. Specifically, you will not be able to install new or
changed CDF products or customizations without first making a
minor change to the following package specification:
!Targets.Target_Key.Io.Floating_Point.M68k_Floats'Spec
As delivered, the CDF products release prior to the D_12_6_5
Environment cannot be promoted to the coded state on a D_12_6_5
system because of changes made to the Environment's compilation
system that enable it to comply with validation. Existing CDFs
are not affected by this problem unless package M68k_Floats is
demoted and an attempt is made to repromote it.
The change you need to make to M68k_Floats'Spec follows.
Note: Changing M68k_Floats'Spec will cause the demotion of
M68k_Floats'Body, M68k_Float_Conversions'Body, and
M68k_Float_Conversions.Based_Value'Body. Demoting
these units will also demote any coded main programs that were
coded with the CDF.
1. Locate the following two representation clauses. They can be
found at the beginning of the private part (line 164 of the
unit).
for Single_Format use
record at mod 4;
Negative at 0 range 0 .. 0;
Exponent at 0 range 1 .. 8;
Fraction at 0 range 9 .. 31;
end record;
for Double_Format use
record at mod 4;
Negative at 0 range 0 .. 0;
Exponent at 0 range 1 .. 11;
Fraction_Hi at 0 range 12 .. 31;
Fraction_Lo at 0 range 32 .. 63;
end record;
2. Move the representation clause for Single_Format so that it
immediately follows the declaration of its type (line 34 of
the unit).
type Single_Format is -- line 34
record
Negative : Boolean;
Exponent : Single_Exponent;
Fraction : Single_Fraction;
end record;
8 May 1992 RATIONAL\f
Release D_12_6_5
for Single_Format use -- move rep clause to here
record at mod 4;
Negative at 0 range 0 .. 0;
Exponent at 0 range 1 .. 8;
Fraction at 0 range 9 .. 31;
end record;
function Convert_Out is new Unchecked_Conversion
(Source => Single_Float,
Target => Single_Format);
function Convert_In is new Unchecked_Conversion
(Source => Single_Format,
Target => Single_Float);
3. Move the representation clause for Double_Format so that it
immediately follows the declaration of its type (now line 60
of the unit).
type Double_Format is -- line 60
record
Negative : Boolean;
Exponent : Double_Exponent;
Fraction_Hi : Double_Fraction_Hi;
Fraction_Lo : Double_Fraction_Lo;
end record;
for Double_Format use -- move rep clause to here
record at mod 4;
Negative at 0 range 0 .. 0;
Exponent at 0 range 1 .. 11;
Fraction_Hi at 0 range 12 .. 31;
Fraction_Lo at 0 range 32 .. 63;
end record;
function Convert_Out is new Unchecked_Conversion
(Source => Double_Float,
Target => Double_Format);
function Convert_In is new Unchecked_Conversion
(Source => Double_Format,
Target => Double_Float);
4. Repromote M68k_Floats'Spec.
5. Repromote M68k_Floats'Body and the other two units that have
been demoted, M68k_Float_Conversions'Body and
M68k_Float_Conversions.Based_Value'Body.
6. Repromote any coded main programs that were coded with the
CDF.
This problem will be fixed in Release6_3_3 of the Bare compiler,
which should be available soon. Rational is also in the process
of creating a new version of the OS2000 CDF product with this fix
RATIONAL May 1992 9\f
Rational Environment Release Information
in place.
5.2. Errors Reported When Archiving Switch Files to Non-D_12_6_5
Machines
The D_12_6_5 release of the Environment makes several changes to
switches. When combined, two of these changes result in error
messages when archiving switch files from D_12_6_5 systems to
previous releases:
* The D_12_6_5 release of the Environment changes the way in
which switch files are copied. When used to copy a switch file
in previous releases, the Archive.Copy procedure copied only
switches that had nondefault values. In D_12_6_5, the
Archive.Copy procedure copies the entire switch file,
including switches that have default values.
* D_12_6_5 also introduces a new library switch (see section
7.7).
As a result of these changes, if you use Archive.Copy to copy
library switches from D_12_6_5 to a system running a previous
release of the Environment, Archive.Copy may generate errors
indicating that certain switches do not exist. These errors can
be ignored; the copy operation will complete successfully.
Note that these errors are not considered a bug and will not be
fixed in future releases.
5.3. Limitation in Archiving between Machines Running Different
Releases
There is a potential problem when performing Archive.Resore
operations between two systems that are running different
releases of the Environment.
Because of changes made in D_12_5_0 (and perpetuated in D_12_6_5)
in the way Archive saves subsystem compatibility databases
(CDBs), you may experience problems when trying to restore a
D_12_5_0 or D_12_6_5 archive on a pre-D_12_5_0 system. For
example, the Archive operation may generate internal errors such
as:
INTERNAL ERROR (declaration mapping): ARCHIVE_IS_BAD restoring
!Subsystem_Name.State.Compatibility.Declaration_Numbers.Unit_
Name
A simple workaround exists. When saving objects to pre-D_12_5_0
systems, specify Version=527 in the the Options parameter of
Archive.Save. For example, the following operation successfully
saves My_View:
Archive.Save (Objects => "My_View",
10 May 1992 RATIONAL\f
Release D_12_6_5
Options => "Version=527",
Device => "Machine.Devices.Tape_0",
Response => "<PROFILE>");
When an attempt is made to restore My_View to a D_12_5_0 or
D_12_6_5 system, Archive.Restore checks to see under what version
of Archive the object was saved and adjusts accordingly.
Note that this problem does not affect:
* Archive.Copy operations, which copy over the network. In this
case, Archive checks the version number on each end and uses
the lower version number of the two.
* Archive operations on text files, Ada units, or other non-CDB
objects.
* Archive operations between systems running D_12_6_5 and
D_12_5_0.
Note also that this is a compatibility issue with how CDBs are
saved and not a bug.
5.4. Problem with Record Representation Clauses and Long_Integer
Type
A record representation clause may not include a component clause
corresponding to a component of type Standard.Long_Integer (or a
type derived, directly or indirectly, from type Long_Integer)
unless an explicit range constraint has been given.
An update that fixes this problem is already being developed and
will be available shortly.
(PRS number 8391844-Gato-Gbd)
5.5. Problem Using DFS Tools with Coprocessors
A problem has been found with the new Diagnostic File System
(DFS) tools, located in !Machine.Dfs. Specifically, the
Fs_Download procedure does not work correctly when attempting to
load a new DFS onto either a series 300C or 400C. This is
considered a bug and will be fixed in a future release.
Furthermore, the Fs_Download procedure cannot be used to load a
new DFS onto a 100. This is a permanent limitation and will not
be fixed.
5.6. Problems with Documentation Tools
The Documentation Tools delivered with the D_12_6_5 release of
the Environment include only the Document Formatter; they do not
RATIONAL May 1992 11\f
Rational Environment Release Information
include the Spelling Checker. If you would like to obtain the
Spelling Checker, contact your Rational representative.
For information about the Document Formatter, see section 6.6.2.
5.7. Problem When Initializing Session Switch Files
A problem has been found in the way in which the Environment
initializes session switch files for sessions other than the
default session. This problem is not introduced by the D_12_6_5
release; however, it has become more obvious with the
introduction of new documentation for session switches in the SJM
book.
Each user's default session (S_1) obtains its initial
session-switch values from system-defined default values. If a
switch file does not exist for session S_1, the session uses the
same system-defined default values.
Subsequent sessions for which switch files have not been created
use the switch values set for the user's default session, S_1. If
a user creates a switch file for any of these subsequent
sessions, the initial values are copied from the system-defined
default values. This is a bug. Subsequent sessions should copy
their initial switch values from the default session, S_1, as
described in the new SJM book.
6. New Environment Interfaces
D_12_6_5 provides a number of new interfaces, including:
* New procedures and functions in:
- Package Access_List_Tools; see section 6.1
- Package System_Maintenance; see section 6.2
- Package Dfs; see section 6.3
* New login policy features; see section 6.4.
* A new subsystem that provides networking tools; see section
6.5.
* New interface and documentation facilities that were
previously delivered separately; see section 6.6.
6.1. New Declarations in Package Access_List_Tools
Package !Tools.Access_List_Tools contains the new procedures and
functions described in the following paragraphs.
12 May 1992 RATIONAL\f
Release D_12_6_5
For complete information about this subprograms, see the new
documentation for package Access_List_Tools in the Library
Management (LM) book or in online help.
6.1.1. Function Grants
function Grants (For_List : Acl;
Desired : Access_Class;
User_Name : String := "") return Boolean;
Returns a Boolean value indicating whether the specified
access-control list grants the specified username the desired
access rights. This function is useful for restricting jobs that
normally have unlimited access, such as servers and other *SYSTEM
jobs. For example, you can use this function to cause a job or
program to operate on objects only if members of the group
Network_Public are permitted the appropriate access to those
objects.
6.1.2. Function Is_In_Group
function Is_In_Group (User_Name : String;
Group_Name : String) return Boolean;
Returns a Boolean value indicating whether the specified username
is a member of the specified access-control group. This function
returns True if the specified user is a member of the specified
access-control group. This function returns False if an error is
detected during the test or if the user is not a member of the
specified access-control group.
(PRS numbers 0-0301-9 and 9723630-0011-5)
6.1.3. Function Is_Valid_Group
function Is_Valid_Group (Name : String) return Boolean;
Returns a Boolean value indicating whether the specified name is a
valid access-control group.
6.1.4. Procedure Remove
procedure Remove (Group : String;
Initial_Acl :
Bounded_String.Variable_String;
New_Acl : out
Bounded_String.Variable_String;
Group_Found : out Boolean);
Removes the entry for the specified group from the specified
access-control list.
RATIONAL May 1992 13\f
Rational Environment Release Information
6.1.5. Procedure Set
procedure Set (For_Object : Directory.Version;
To_List : Acl;
Status : in out Simple_Status.Condition;
Action_Id : Action.Id);
Setting an object's ACL requires owner access to the nearest
world enclosing the object.
Note that setting a world's ACL does not require owner access to
the world itself, provided that you have owner access to its
parent world. This allows you to change the ACL of a world when
no one has owner access to it.
This procedure is the same as other Set procedures, with the
addition of an Action_Id parameter.
6.1.6. Procedure Set_Default
procedure Set_Default (For_World : Name;
To_List : Acl;
Status : in out
Simple_Status.Condition;
Action_Id : Action.Id);
Sets the default access-control list (ACL) for the specified world
or worlds.
Setting a world's ACL requires owner access to that world. A
world's default ACL is used to initialize the ACLs of new Ada
units and files created in the world.
This procedure does not modify the ACLs of already existing
objects whose ACLs were set by the previous default ACL.
This procedure is the same as other Set_Default procedures, with
the addition of an Action_Id parameter.
6.2. New Procedures in System_Maintenance Subsystem
!Commands.System_Maintenance'Spec_View contains the new
procedures described in the following paragraphs.
6.2.1. Procedure Last_Gasp_Destroy
procedure Last_Gasp_Destroy (Name : String);
Caution: Use this procedure only as a last resort.
Forcibly removes an object from a directory. Use this procedure
only when you've tried every other means of deleting an object or
14 May 1992 RATIONAL\f
Release D_12_6_5
set of objects. Normally:
*
This procedure should be used only if you are consistently
getting Version_Error on a particular object.
* This procedure can be used instead of elaborating Dir_Tester.
* This procedure should not be used if you are getting "Key not
found" errors.
This procedure should be used only by Rational personnel or at
their discretion. For a detailed description, including a
complete list of steps you should try before using this
procedure, see this procedure's specification:
!Commands.System_Maintenance'Spec_View.Units.Last_Gasp_
Destroy'Spec
Note that you must be operating in privileged mode to execute
this procedure.
6.2.2. Procedure Release_Tape_User
procedure Release_Tape_User (Drive : Natural);
Resets the specified tape drive so that it is free, thereby
allowing tape-mount requests to proceed without "Drive is in use"
errors. This procedure also attempts to rewind the tape.
Note that this procedure does not physically reset the drive.
Note also that you must be operating in privileged mode to
execute this procedure.
The fully qualified name of this procedure is:
!Commands.System_Maintenance'Spec_View.Units.Release_Tape_User
(PRS number 9123690-0160-1 and CSR number 4788)
6.2.3. Procedure Show_Load_Proc_Unit_Names
procedure Show_Load_Proc_Unit_Names (Load_Proc : String :=
"<SELECTION>";
Response : String :=
"<PROFILE>");
Obtains information that allows you to find the objects from
which a loaded main program (Load_Proc or Load_Func) was created.
Specifically, this procedure obtains the Ada object instance ID
numbers for the Ada units that make up the source code for the
RATIONAL May 1992 15\f
Rational Environment Release Information
loaded main program specified in the Load_Proc parameter.
The display produced by this procedure includes lines of the
form:
Library.Resolve ("<[ADA, 12345,1]>");
These lines indicate the Ada object instance ID of one or more of
the original Ada source units used to create the loaded main
program. If those Ada source units still exist, and if they exist
on the current machine, then the Environment pathnames of those
units are also displayed.
If the original source units do not exist (because they have been
edited, moved, renamed, or deleted), or if the loaded main
program was copied from another machine, then no pathname is
printed. To attempt to locate the source units for a loaded main
program that was copied from another machine:
1. Take the Library.Resolve lines that were printed by the
Show_Load_Proc_Unit_Names procedure (as shown above).
2. Log into each R1000 where the source units might still exist.
3. Execute the Library.Resolve commands.
If the source unit exists on any of these machines, the
Library.Resolve command returns the fully qualified pathname of
that unit.
The fully qualified name of this procedure is:
!Commands.System_Maintenance'Spec_View.Units.Show_Load_Proc_
Unit_Names
(PRS number 9123690-0148-4)
6.2.4. Procedure Show_Tape_Users

6.3. New Features in Package Dfs
16 May 1992 RATIONAL\f
Release D_12_6_5
6.3.1. Support Tools
The access routines for the Environment's Diagnostic File System
(DFS) have been enhanced to make it easier to upgrade the DFS and
to aid in problem resolution at the DFS (and lower) level. These
changes allow an operator to:
* Read a DFS tape into the Environment.
* Create an Environment MT Image file object, containing the
contents of that tape. (An MT Image object contains an ordered
collection of DFS files. Creation of an MT Image object makes
it possible to handle a set of DFS files as a single object.)
* Download to the DFS from the Environment (either from an
arbitrary Environment file object or from an Environment MT
Image object created from a DFS tape).
Support tools to create DFS tapes and move DFS files within the
DFS are also provided. These support tools take the form of:
* Several new commands in package
!Machine.Dfs'Spec_View.Units.Dfs
* A new package, !Machine.Dfs'Spec_View.Units.Install_Tools
For complete details about the new commands in package Dfs and
the new package Install_Tools, see the exported specifications
online.
For information about changes to existing commands in package
Dfs, see section 7.12.
6.3.2. Dfs_Release File
To aid in tracking updates to the DFS, D_12_6_5 also includes a
new Dfs_Release file, which contains the release date, number,
and notes for the current DFS release. To read Dfs_Release from
the Environment, execute the following command:
"!Machine.Dfs'Spec_View.Units".Dfs.Copy
(Dfs_Filename => "Dfs_Release",
Env_Filename => "Environment filename for
output",
Allow_Overwrite => False);
Then traverse to the file specified in the Env_Filename
parameter. The file should contain DFS release information such
as the following:
DFS D3.0
April 14, 1992
RATIONAL May 1992 17\f

9123690-0164-4
CSR => 5559
Software flow control om port 16 has been repaired.
This file was originally introduced in release D_12_5_0A.
6.4. New Login_Policy World
D_12_6_5 includes a new world, !Machine.Login_Policy, in which
system managers can create subprograms and files that:
* Establish a policy monitoring and responding to successful and
failed login attempts.
* Specify the login message that is displayed when users connect
to the R1000.
For security purposes, this world is delivered with Operator
access only. As delivered, the Login_Policy contains no
procedures; sites that do not take advantage of this feature will
notice no change in the system behavior.
These features are described in more detail in the following
paragraphs.
6.4.1. Establishing a Login Policy
The login manager now contains a call to operator-defined
procedures that determine site-specific login policies. Although
primarily intended as a mechanism for system managers to react
promptly to invalid login attempts, these facilities also provide
the basis for additional site-specific features.
18 May 1992 RATIONAL\f
Release D_12_6_5
When a login attempt is made, the Environment's login manager now
checks for the existence of operator-defined procedures
Successful_Login and Failed_Login in world !Machine.Login_Policy.
If these procedures exist, then:
* If the login attempt was successful, the login manager calls
Successful_Login.
* If the login attempt was not successful, the login manager
calls Failed_Login.
The user-defined procedures must be placed in
!Machine.Login_Policy and have the following specifications:
procedure Successful_Login (Username : String;
Session : String;
Time : String;
Port : Natural;
Network_Name :
Transport_Defs.Network_Name;
Host_Id :
Transport_Defs.Host_Id;
Socket_Id :
Transport_Defs.Socket_Id;
Error_Status : Natural);
procedure Failed_Login (Username : String;
Session : String;
Time : String;
Port : Natural;
Network_Name :
Transport_Defs.Network_Name;
Host_Id : Transport_Defs.Host_Id;
Socket_Id :
Transport_Defs.Socket_Id;
Error_Status : Natural);
The parameters of these procedures are described below:
* Username: the name supplied at the Enter username prompt
during the attempted login or the null string if this
information has not yet been entered.
* Session: the session specified at the Enter session name
prompt during the attempted login or the null string if this
information has not yet been entered. If a [#Return#] is
supplied at the Enter session name prompt, session S_1 is
assumed.
* Time: the date and time at which the login attempt occurred.
The format for this string is the date, one blank space, and
then the time. The date is of the form month/day/year, and the
time is expressed in military format. Procedures from package
!Tools.Time_Utilities can be used to process this information.
RATIONAL May 1992 19\f
Rational Environment Release Information
* Port: the number of the R1000 port on which the login attempt
is being made.
* Network_Name: identifies one of several available protocol
stacks for the current connection. For example, the value
TCP.IP is passed for a Telnet connection, and the null string
is passed for a direct connection to the R1000. See package
Transport_Defs and subsystem Telnet_Tools in !Tools.Networking
for procedures to process this variable.
* Host_Id: identifies the machine within a network making the
connection. See package Transport_Defs and subsystem
Telnet_Tools in !Tools.Networking for procedures to process
this variable.
* Socket_Id: identifies a program within a machine. See package
Transport_Defs and subsystem Telnet_Tools in !Tools.Networking
for procedures to process this variable.
* Error_Status: a status code that indicates either success or
the reason that the login attempt failed. The status codes
are:
0 - Successful 1 - Bad_Username_Or_Password
2 - Expired_Password 3 - Abandoned_Login
4 - Read_Timed_Out 5 - Read_Error
6 - Input_Unreadable 7 - Terminal_Type_Unreadable
8 - Resource_Restriction 9 - Product_Not_Authorized
10 - Internal_Error
Note: The Successful_Login and Failed_Login procedures are run
under the identity of *SYSTEM to allow privileged operations to
be performed. For this reason, system managers may want to use
existing access-control mechanisms to control access to these
procedures and ensure system security. As it is delivered, the
Login_Policy world is accessible only to the members of group
Operator.
If the procedures exist, and if an attempt to run either of these
procedures is unsuccessful, this is noted in the system error
log. If the procedures do not exist, then the login process runs
as usual, and nothing is recorded in the system log.
This change does not affect the disconnect and login behavior
options for a port. These options are still set separately
through !Machine.Initialization or through commands in package
!Commands.Terminal.
(PRS number 9723630-0074-7)
6.4.2. Specifying the Login Message
The D_12_6_5 release provides the ability for system managers to
specify the message users see when they connect to an R1000.
20 May 1992 RATIONAL\f
Release D_12_6_5
The system's standard message indicates the release number for
the current Environment, a name identifying the machine, the port
number through which the connection has been made, and the
current date and time:
Rational Environment D_12_5_0; Roget - Ada Tech Pubs; Port
232.
January 16, 1992 at 2:07:34 PM
In D_12_6_5, system managers can place other messages in a text
file of the name !Machine.Login_Policy.Login_Text. If this file
exists, its contents are displayed when users connect to the
R1000. Placing the string <Standard_Message> on its own line in
this file causes the standard login message to be displayed (in
addition to any other text in the file).
(PRS number 9723630-0025-8)
6.5. New Telnet_Tools Subsystem
This new subsystem provides programmatic interfaces to Rational
Networking as well as some new utility software. It includes
three new packages:
* !Tools.Networking.Telnet_Tools'Spec_View.Units.Telnet_Port
* !Tools.Networking.Telnet_Tools'Spec_View.Units.Telnet_Protocol
* !Tools.Networking.Telnet_Tools'Spec_View.Units.Telnet_Tools
For more information, see the exported specifications online.
6.6. Products Now Delivered with the Environment
6.6.1. Rational X-Interface and Windows-Interface
Rational's X-Interface (RXI) and Windows Interface (RWI) have
become the primary access mechanisms to the Environment. In
response to this evolution, the most recent releases of RXI
(10_9_0) and RWI (10_1_1) are delivered with the D_12_6_5 release
of the Environment.
Note that RXI and RWI still must be installed using a separate
installation process; they are not installed during Environment
installation:
* If you already have RXI and/or RWI installed on your system,
you do not need to install them again. D_12_6_5 does not
include any changes to these products.
* If you do not have RXI and/or RWI installed on your system and
would like to install one or the other, contact your Rational
RATIONAL May 1992 21\f
Rational Environment Release Information
representative for installation instructions, keyboard
overlays, and documentation. To install RWI, you will also
need to obtain a diskette that contains software to be
installed on the PC.
* If you have purchased a new system, the installation
instructions for RXI and RWI are included with that system.
Contact your Rational representative to obtain keyboard
overlays and documentation.
For further information about RXI token issues, see section 7.14.
ll problem reports concerning the improper consumption of tokens
by RXI
6.6.2. Documentation Tools
D_12_6_5 includes Rational's Documentation Tools as part of the
standard Environment. As part of the D_12_6_5 release, a new
release of the Document Formatter has been introduced
(Rev10_7_12) and the system default activity has been updated to
reverence this release. To ensure backward compatibility, the
previous version of the Document Formatter (Rev10_7_7) has been
preserved and can be used simply by changing your activity file.
Although the Spelling Checker is part of Rational's Documentation
Tools, it has not been included in the D_12_6_5 Environment
release (see section 5.6). If you would like to obtain the
Spelling Checker, contact your Rational representative.
Documentation is available for both the Document Formatter and
the Spelling Checker. For information, contact your Rational
representative.
7. Changes from D_12_5_0
This section describes the changes, enhancements, and
user-visible problem fixes that D_12_6_5 makes to existing
features of the Environment. The information in this section is
presented in roughly the same order in which it would be found in
the Rational Environment Reference Manual (ERM):
* Information on editing specific types of objects such as Ada
units (EST) (sections 7.1 and 7.2)
* Information on session and job management (SJM)-specifically,
packages Job, Remote_Passwords, Operator, and Search_List
(section 7.4)
* Library-management information (LM), including changes to
archive (section 7.5), compilation (7.6), library switches
(7.7), and other library-management facilities (7.8)
* Device input and output (DIO) changes (section 7.9)
22 May 1992 RATIONAL\f
Release D_12_6_5
* System-management information (SMU), including changes to
system backup (section 7.11), the Diagnostic File System (DFS)
(7.12), crash analysis (7.13), token policies (7.14), and
miscellaneous system-management facilities (7.15)
* Information about subsystems and CMVC (PM) (section 7.16)
* Information about changes to the Math_Support subsystem
(section 7.17)
* Information about other miscellaneous changes (section 7.18)
7.1. Changes to Package Common
Performing Common.Definition on an object in a generic
instantiation now takes you to the declaration in the generic.
(PRS numbers 9123690-0163-9, 9123690-0165-3, 9123690-0169-0, and
9723630-0122-0 and CSR numbers 5501, 5454, and 5707)
The Common.Format procedure has been fixed so that it no longer
destroys the contents of an Ada unit when an attempt to format
that unit fails. (PRS numbers 1704151-Shei-Jst, 2437110-Sier-Geb,
5172201-Cook-Swb, 7039962-Sier-Geb, 7030779-Zebr-Lore,
8068463-Mago-Sdj, 9123690-0156-7, 9123690-0175-9, and
9123690-0181-8 and CSR numbers 4786 and 6261)
7.2. Changes to Editing Ada Units
The Ada.Make_Inline procedure now properly maintains Sm_Subunits.
Sm_Subunits is an attribute on the DIANA nodes for compilation
units. Specifically, Sm_Subunits is a sequence of the subunit
Stub_Ids that exists for that unit. (PRS number 6452721-Shei-Jst)
The Ada.Show_Unused procedure no longer erroneously flags an
enumeration-type declaration as unused when the enumeration
type's literals are referenced elsewhere. (PRS number
9123690-0134-5)
Procedures Ada.Withdraw, Install_Unit, Install_Stub, and
Make_Separate now require only that the executing user have
Create access to the enclosing world or view to enter the unit or
stub into the library listing. This change fixes a problem
introduced in D_12_5_0 in which Owner access was required. (PRS
number 9123690-0171-3 and CSR number 5841)
Procedure !Commands.Dependents.Find now releases actions that are
no longer needed. (PRS number 9723630-0120-7)
A problem has been fixed so that an attempt to incrementally edit
a statement that depends on another statement that has been
incrementally demoted itself no longer fails. (PRS number
6265678-Sier-Geb)
RATIONAL May 1992 23\f
Rational Environment Release Information
The Environment now demotes units in the correct order when:
* An attempt is made to incrementally demote a type
* That type is used in a procedure's parameter list
* Both that procedure and the original type are used as
parameters in a generic instantiation
(PRS number 9123690-0161-1)
A problem has been fixed so that the following valid incremental
insertions now are accepted:
package P is
type T is private;
type A is array (1 .. 10) of T; -- insert 1
private
type T is new Integer;
X, Y : A; -- insert 2
B : Boolean := X < Y; -- insert 3
end P;
(PRS number 9924694-Mago-Sdj)
7.3. Changes to Debugging
Function Debug_Tools.Get_Exception_Name now correctly returns the
fully qualified name of the exception, regardless of the setting
of the R1000_Cg.Retain_Delta1_Compatibility library switch. In
previous releases, if this switch was set to False, the function
returned a string such as <Exception: Unit =-35983540864679680,
Ord = 0>. (PRS numbers 12729-Star and 9123690-0160-7 and CSR
number 4626)
7.3.1. Quitting While the Debugger is Running
In previous releases of the Environment, if your session was
terminated -for example by Quit or Operator.Force_Logoff-while a
job under the control of the debugger was running, a deadlock
could occur. The symptoms of this deadlock could be any
combination of the following:
* Job 4 stuck in Awaiting_Entry
* Jobs stuck In_Fa_Queue
* Jobs hanging on Quit
Most of these problems have been fixed. If, however, a job hangs
during a Quit, it is now always possible to use Job.Kill to kill
all debugger jobs, causing the system to resume normal operation.
24 May 1992 RATIONAL\f
Release D_12_6_5
(PRS numbers 9123690-0159-0, 9123690-0159-1, 9123690-0172-6, and
9123690-0183-3 and CSR numbers 4740, 5142, 5917, and 6091)
7.4. Changes to Session and Job Management
Job.Kill has been modified so that it can kill editor jobs-even
unallocated jobs-and find any tasks holding actions and abort
them. The user must have operator capability to perform these
tasks. (PRS numbers 5360143-Rati-Jls and 9123690-0166-0)
The remote-passwords facility has been changed so that *SYSTEM
jobs, such as machine initialization and spoolers, now use the
Operator password as the key for decrypting remote-passwords
files. To instruct a *SYSTEM job to use a remote-passwords file,
set the remote-passwords file for the job by calling
Profile.Set_Remote_Passwords from within the job. For additional
information, see package !Commands.Remote_Passwords in the new
Session and Job Management (SJM) book or in online help. (PRS
number 9123690-0166-5)
Special names such as "<IMAGE>" can no longer be inserted either
directly into searchlists or in indirect files named in
searchlists. Be aware, however, that if you have a special name
already in a searchlist and if you attempt to delete that
searchlist or searchlist entry, the system may crash, as it did
in previous releases. (PRS number 9123690-0138-2)
The Program.Change_Identity command now delays when it encounters
an illegal username and password pair. The length of the delay
increases with each illegal encounter. (PRS number
3289131-Gato-Bas)
When logging on to the system in previous releases, if you
entered a valid username and an invalid password and if the
correct password associated with that username had expired, the
password-expiration warning was emitted. The password-expiration
warning implies that the username was correct. This situation has
been fixed so that no information is given when either the
username or password is invalid. (PRS number 4289272-Voya-Cmd)
7.5. Archive Changes
The comments in the specification for package Archive have been
improved. In particular, the comments now include all supported
options for the Archive.Copy, Archive.Restore, and Archive.Save
procedures. (PRS number 9123690-0131-8)
7.5.1. Copying Ada Units with Subobjects
The Archive.Copy, Archive.Save, and Library.Copy procedures now
copy non-Ada subobjects of Ada units that are not managed by one
of Rational's layered products as if they were Ada subunits.
RATIONAL May 1992 25\f
Rational Environment Release Information
These subobjects are sometimes called associated files and
indicated in library images by brackets (<>). A recursive copy of
a parent unit now will pick up the subobject, but a nonrecursive
one will not. In previous releases of the Environment, non-Ada
subobjects of Ada objects were not copied as part of a recursive
copy operation.
7.5.2. Archiving Library Switch Files
The Archive.Copy and Archive.Save procedures have been changed so
that archiving a library switch file now archives the complete
switch file. (In previous releases, only nondefault values were
archived.) As a result, restoring a D_12_6_5 switch file to a
system running a previous release will result in messages of the
form: Switch does not exist. These messages result from the fact
that new switches exist in the D_12_6_5 switch file that do not
exist in switch files from the previous release. The messages are
for your information only; the Archive operation will complete
successfully. For information about the new switches, see section
7.7.
7.6. Compilation Changes
Procedures in package !Commands.Compilation now print correct
symbols for log messages. In particular, commands no longer use
the note symbol (---) for messages that should be auxiliary
(:::). For information about log-message symbols and their
meanings, see the documentation for !Tools.Profile.Msg_Kind. (PRS
number 1000002-Sier-Geb)
A problem has been fixed in which compilation operations
sometimes would hang-without generating an error message-if the
program library was locked. In particular, if you executed
Definition ("<*Program_Library>") to display a world's program
library, the operation would lock the program library. If you
attempted to perform a compilation operation while the program
library was locked, the compilation operation would hang. In
D_12_6_5, compilation operations now time out and produce an
error message indicating that the program library is locked. (PRS
number 2949267-Etoi-Hts)
7.6.1. Installing Units
Note: The D_12_6_5 release of the Environment contains a number
of changes to adhere more closely to the standards defined in the
Reference Manual For the Ada Programming Language (LRM). In
certain cases, these changes can cause source code that installed
in the past to install no longer. Existing installed or coded
units are not affected by these changes.
Promoting a unit to the installed state for the first time now
requires only that the executing user have Create access to the
26 May 1992 RATIONAL\f
Release D_12_6_5
enclosing world or view. This change fixes a problem introduced
in D_12_5_0 in which Owner access was required. (PRS number
9123690-0171-3 and CSR number 5841)
Semantic checking has been fixed so that the Environment no
longer allows a private type to be used as a generic formal
parameter before the type's completion in the private part; this
way of using a private type is not legal in Ada (see LRM 7.4.1
(4)). (PRS number 9123690-0128-9)
In accordance with LRM 13.4.(8), semantic checking now allows
implementation-dependent attributes to be used in record
representation clauses. (PRS number 1000000-Sier-Geb)
Semantic checking has been improved so that an extra nonterminal
([expression] prompt) used as a record aggregate is flagged now
as an error. In previous releases, an error was not generated
until code was generated. (PRS number 9123690-0128-6)
Semantic checking now properly supports the renaming of
subprograms. In previous releases, problems were encountered if
the renamed subprogram had a parameter for which the default
value was an expression that could be misinterpreted as a
predefined type. (PRS number 9123690-0156-3 and CSR number 4845)
In accordance with LRM 13.1 (7), semantic checking no longer
allows the following source code to install (PRS number
1140702-Gato-Gbd):
package Csr5310 is
type Type_1 is
record
Q_Addr_2 : Integer;
end record;
Forcing_Occurrence : constant Type_1 := (Q_Addr_2 => 0);
-- The compiler detects the violation against LRM 13.1 (7)
if the
-- object is not constant.
for Type_1 use
record at mod 2;
Q_Addr_2 at 2 range 0 .. 4 * 8 - 1;
end record;
end Csr5310;
A problem has been fixed in which performing semantic checking
more than once on a single unit results in the disappearance of
the error underlines. This problem has been fixed so that the
same error underlines reappear each time the unit is
semanticized. (PRS number 9123690-0157-9 and CSR number 5005)
RATIONAL May 1992 27\f
Rational Environment Release Information
Both the R1000 compiler and the Mc68020_Bare Cross-Development
Facility (CDF) (Rev5_1_1) now flag as an error any renaming of a
record component in which the record object is returned as the
result of a function call (see LRM 8.5 (4)). Attempts to install
subprograms containing such renames now fail with the message
Expanded name name is not a renamable object. (PRS number
9123690-0169-8)
Semantic checking now allows the following to be applied to an
enumerated type:
* An enumeration representation clause that starts with negative
values
* A size clause that comes before the enumeration representation
clause
(PRS number 9123690-0180-7 and CSR number 4844)
In accordance with LRM 3.2 (9) and 3.3.2 (2), semantic checking
no longer allows you reference a type mark that is not a simple
name. (PRS number 9123690-0152-8 and CSR number 4735)
Messages have been improved so that if you reach the
architectural limit for the size of a DIANA node (2**23 bytes),
the coding attempt now fails gracefully with the message Promote
Failed - Other Error in the message window and with the message
!!! Action.Acquire Invalid_Class nnnnnnnnnn for instance nnnnnn
machine id 1 on the console error log. (PRS number
8277786-Voya-Bas)
Error messages have been improved so that if you attempt to
declare a record with more than 256 fields, the compiler now
generates a message such as Field F in record type R exceeds the
number of fields implementation limit of 256, and the offending
unit fails to install. (PRS number 9123690-0142-3)
Messages have been improved so that if the physical
representation of an enumeration type does not have a range of
Integer'Range (as specified in LRM 3.4.1), semantic checking
fails with a message such as *UNIVERSAL_INTEGER* ... Constant
expression not in Integer'Range. (PRS number 5700190-Etoi-Tnu)
The error message generated when a body fails to install has been
punctuated for easier readability. Specifically, quotation marks
have been added around the declaration of the body. The message
now appears similar to the following: 1: ERROR The spec for
"package body FOO is " could not be installed. (PRS number
10270-Shei-Swb)
7.6.2. Coding Units
The R1000 code generator now successfully codes any package that
declares a constant of a subtype such that the subtype is:
28 May 1992 RATIONAL\f
Release D_12_6_5
* Externally declared
* Of an integer type that uses an explicit conversion for a
range constraint
In previous releases, attempts to code these packages failed with
Constraint_Error. (PRS numbers 9123690-0145-5 and
306859-Cook-Swb)
Messages have been improved so that if you attempt to code a unit
that instantiates a generic whose original declaration has been
corrupted, you no longer get an internal error. The primary cause
of this kind of corruption is using
Program_Library_Maintenance.Build on Delta-1-style code views.
(CSR number 5215)
As documented in section 1.2.10 of Appendix F for the R1000
Target of the LRM, the R1000 code generator now ignores pragma
Private_Eyes_Only for generic units. (PRS number 9123690-0151-1
and CSR number 4723)
A problem has been fixed in which the R1000 code generator failed
with a Constraint_Error when coding a very large task-entry
family. The code generator now codes the task-entry family
successfully and generates the following warning: 1: WARNING
Declaring a very large entry family (may cause STORAGE_ERROR):
E1. (PRS number 4967545-Voya-Phil)
You now can control whether the Environment allows you to promote
to the coded state Ada units that contain [statement] prompts.
For details, see the description of the new
Semantics.Reject_Statement_Prompts library switches in section
7.7. (PRS number 9123690-0143-2)
The compiler now handles sparse types of discriminants properly.
In previous releases, when sparse types were used as discriminant
types, the compiler would not work correctly in assigning the
variant part of the record, and the incorrect case alternative
would be chosen. (PRS number 9123690-0166-6 and CSR number 5666)
7.6.3. Loading and Executing Units
The Compilation.Load procedure has been changed so that it always
builds the specification of the loaded main program (Load_Proc or
Load_Func) from the specification of the unit specified to the
Load procedure. If a unit body is specified, the unit
specification associated with that body is used. This practice
ensures that the loaded main program obtains its context clause
from the unit specification. If the Load procedure used the
context clause from the unit body, and that unit body depended on
the specification's context clause, the procedure would fail with
semantic errors. (PRS number 6821610-Stan-Deg)
RATIONAL May 1992 29\f

Attempting to execute a derived procedure inherited by
instantiation in a generic that is itself instantiated no longer

Declaring a private derived type of
!Tools.Unbounded_String.Variable_String no longer causes an
unhandled exception at runtime when the unit that declared the

If an unhandled exception is encountered at the outermost level,
programs coded with the R1000_Cg.Retain_Delta1_Compatibility

7.6.4. Program Libraries
The Program_Library_Maintenance.Verify procedure and function
have no valid options. The comments in the specification for
these subprograms now state this explicitly. The full pathname
for these subprograms is:
!Tools.Program_Library'Spec_View.Units.Program_Library_
Maintenance.Verify
(PRS number 9123690-0131-7)
7.7. Changes to Library Switches
D_12_6_5 introduces two new library switches and changes the
default value of one.
Because of the addition of these two switches, copying library
switch files from D_12_6_5 to previous releases generates error
messages indicating that certain switches do not exist. These
errors can be ignored; the copy operation will complete
successfully. This behavior is also mentioned in section 5.
D_12_6_5 also includes new online help for several library
switches. See section 8.3 for a list of these switches.
7.7.1. New Switch: Semantics.Limit_Semantic_Messages
This switch controls the number of semantic messages (errors and
warnings combined) that can be attached to an Ada image. Those
messages with numbers greater than this limit will be discarded.
Discarded messages can be regenerated by increasing the limit
specified in this switch and resemanticizing the image. The
default is 200 messages.
30 May 1992 RATIONAL\f
Release D_12_6_5
Note that generation of an extremely large number of messages for
a single unit can cause semanticizing to take an excessive amount
of time. Setting this switch to a lower number may speed semantic
checking.
(PRS number 9123690-0136-8 and CSR number 3956)
7.7.2. New Switch: Semantics.Reject_Statement_Prompts
This switch controls whether the Environment allows you to
promote to the coded state Ada units that contain [statement]
prompts. When False (the default), units with [statement] prompts
can be coded; an error is generated only if an attempt is made to
execute the prompt. When True, units that contain [statement]
prompts cannot be coded. Setting this switch to True may cause
code that was able to code in the past to code no longer but will
not affect units that are coded already.
(PRS number 3336165-Shei-Jst and 9123690-0143-2)
7.7.3. Change to Default Value of
R1000_Cg.Retain_Delta1_Compatibility Switch
The D_12_1_1 release of the Environment contained a major
revision of the R1000 compiler. The D_12_1_1 version of the
compiler has been validated under releases 1.10 and 1.11 of the
Ada validation suite (ACVC 1.10 and 1.11) and includes
significant new features, improved generated-code quality, and
numerous bug fixes.
Certain of the compiler's features and bug fixes are available
only when explicitly enabled by the Retain_Delta1_Compatibility
library switch. This is because enabling these features and bug
fixes causes the compiler to produce code that is incompatible
with the code generated by versions of the compiler prior to
D_12_1_1.
D_12_6_5 changes the default value of this switch to False,
allowing the compiler to take advantage of the features of the
D_12_1_1 compiler unless otherwise specified. This change affects
all new switch files created using Switches.Create or
Switches.Edit. It also affects all new systems. Installation of
D_12_6_5 preserves the current settings in switch files so that
work in progress should not be significantly affected unless new
switch files are created.
Note that units coded with one setting of the switch may
reference units coded with the switch set the other way. However,
there is one restriction: when a main program is prelinked, a
check is made to ensure that each unit in a spec view was coded
with the same switch setting as the corresponding unit in the
load view. The compatibility checker also makes this check when
checking load view/spec view compatibility.
RATIONAL May 1992 31\f
Rational Environment Release Information
To avoid confusion, it is recommended that you use the same
switch setting for all units in a given view. Furthermore, to
prevent problems with spec view/load view compatibility, it is
recommended that you use the same switch setting for all views in
a given subsystem.
There is no need for you to convert existing code that was
compiled with the Retain_Delta1_Compatibility switch set to True.
However, if you choose to convert existing code, you must set the
switch to False in each of the affected libraries or views,
demote the units to the installed state, and then repromote them
to the coded state. Code views cannot be recompiled and therefore
should be destroyed.
For more information about the effects of this switch, see the
new Library Management (LM) book and the D_12_1_1 release
information. (Release information can be found online in
!Machine.Release.Release_Notes.)
7.8. Changes to Other Library Management Facilities
Commands in package !Commands.Access_List now print log messages
indicating when they have completed and whether they completed
successfully. Commands in package Access_List now also print the
correct symbols for log messages. For information about
log-message symbols and their meanings, see the documentation for
!Tools.Profile.Msg_Kind. (PRS number 1000001-Sier-Geb)
Comments have been added to the specification for the
Library.Copy procedure to more accurately describe the default
value for the Volume parameter. For additional information, see
the documentation for Library.Nil in the new LM book and in
online help. (PRS number 9123690-0150-4)
The Library.Move procedure no longer moves any part of an Ada
unit-either the specification or body-without sufficient access
to the destination library. In previous releases, if you
attempted to move a unit specification and body pair in a single
operation, the Move command would fail to copy the unit
specification but would successfully copy the unit body. (PRS
number 2679572-Roge-Srp)
The Library.Create@ procedures now require that the executing
user have only Create access to the enclosing world or view. This
change fixes a problem introduced in D_12_5_0 in which Owner
access was required. (PRS number 9123690-0171-3 and CSR number
5841)
Procedures !Commands.Links.Edit and Links.Display now require
Owner access to the world for which the links are being edited or
displayed. In previous releases, only Read access was required.
(PRS number 5367576-Blut-Smp)
32 May 1992 RATIONAL\f

7.9. Changes to Device Input and Output
The Sequential_Io.Read procedure and the
Polymorphic_Sequential_Io.Read procedure
have been fixed so that they no longer raise
!Lrm.System.Operand_Class_Error or Nonexistent_Page_Error when an
attempt is made to read the first character in a file.
(CSR number 6016)
7.10. Changes to Printing
The Abbreviations.Print command now handles print requests that
specify multiple Ada units in the same way that it handles a
print request for a single Ada unit. That is, when multiple
objects are specified to the Object_Or_Image parameter and when
all of those objects are Ada units, the Print command now
processes the Highlight_Reserved_Words_For_Ada parameter. If any
of the objects specified are not Ada units, this parameter is
ignored. (PRS number 9123690-0168-2 and CSR number 5773)
The Queue.Print command now forms valid VMS filenames for print
requests. In previous releases, if you printed a file to a queue
that was physically located on another machine and if that queue
was FTP-based, then the filename formed for FTP transfer was
invalid for VMS. When the print spooler tried to dequeue the
request, several errors were logged and the queue was disabled.
(PRS number 9123690-0168-8 and CSR number 5710)
7.11. Changes to System Backups
The default parameter for the System_Backup.Backup procedure has
been corrected so that the procedure now semanticizes
successfully in command windows. Specifically, the value of the
Variety parameter has been changed from Full to
System_Backup.Full. See the new System Management Utilities (SMU)
book or online help for additional information about this
command. (PRS numbers 1711335-Gato-Gbd and 9123690-0135-8)
The process of recovering a system backup has been changed so
that it always prints some form of diagnostic message whenever it
detects a situation in which it cannot complete the restoration.
Furthermore, additional log messages indicate the beginning and
completion of major stages in the restoration process. In
previous releases, when a problem occurred while a backup was
being restored, the process sometimes would hang without
generating any messages. (PRS number 9123690-0133-9)
The Verify_Backup procedure has a new parameter, Wait_Until, that
allows you to specify the amount of time the procedure must wait
before starting. The tape should be mounted immediately, but
Verify_Backup does not start reading the tape until Wait_Until
has expired. The fully qualified pathname for Verify_Backup is:

7.12. Changes to the Diagnostic File System (DFS)
7.12.1. Renamed Procedures
D_12_6_5 changes the specification of package
!Machine.Dfs'Spec_View.Dfs. Specifically, the Dfs_ prefix has
been removed from the names of the procedures introduced in
D_12_5_0:
* Procedure Dfs_Copy is now procedure Copy
* Procedure Dfs_Directory is now procedure Directory
* Procedure Dfs_Display is now procedure Display
* Procedure Dfs_Make_Copy is now procedure Make_Copy
* Procedure Dfs_Open is now procedure Open
* Procedure Dfs_Read is now procedure Read
Several new procedures also have been added to package Dfs; see
section 6.3.
7.12.2. Analyze_Crashdump Prompts for Input
Procedure Analyze_Crashdump by default now queries for input in
an Envirnoment I/O window, rather than from within the log file.
The full pathname for Analyze_Crashdump is
!Machine.Dfs'Spec_View.Units.Analyze_Crashdump. (PRS number
9123690-0165-6 and CSR number 5588)
7.13. Changes to Crash Analysis
7.13.1. Changes to the Crash Analysis Procedures
The D_12_6_5 release includes enhancements to the process of
analyzing R1000 crashes. In particular:
* Much of the process has been automated so that the system will
capture as much information as possible and often will reboot
automatically.
* A series of questions and menus have been added to the crash
analysis process that:
34 May 1992 RATIONAL\f

- Capture system-crash state
- Analyze system hardware
For complete details, see Appendix B, "Diagnostic Crash
Procedures."
(PRS numbers 7483032-Gato-Jls and 7733953-Gato-Vnv)
7.13.2. Change to Crashdumps and Tombstones
A problem with incomplete crashdump and tombstone files that was
introduced in D_12_5_0 has been fixed. Crashdumps and tombstones
now work correctly, and the trace and crash reason appear
correctly in the error logs.
This fix was released originally in DFS release D_12_5_0A
(D2.2A).
7.14. Changes to Token Policies
To simplify token administration, two changes have been made to
token management for D_12_6_5:
* Environment-session tokens now can be transferred between
Series 400 and 300 machines.
* The Rational X Interface (RXI) and Windows Interface (RWI) no
longer require special product tokens. These products now are
bundled with the Environment and are restricted only by
Environment session tokens.
Rational's other token-management facilities have been tightened
to more rigorously account for other product tokens. Although the
number of tokens has not been changed for any particular site,
system, or product, you may discover that you are running out of
tokens more frequently than in the past.
7.14.1. Transferring Tokens between Series 400 and 300
Beginning with D_12_6_5, Environment tokens may be transferred
between Series 400 and Series 300 R1000s. That is, Full Session
tokens and Login tokens now can be transferred between machines
of different series. This change is intended to make it easier to
maintain sites that have both Series 400 and 300 machines and to
enable those sites to move tokens in response to project needs.
To make this token transfer possible, the
!Commands.System_Maintenance'Spec_View.Units.Accept_Tokens and
Donate_Tokens procedures have been changed.
RATIONAL May 1992 35\f
Rational Environment Release Information
For example, assume that you have a Series 400 with twelve Full
Session tokens and a Series 300 with six Login tokens. To
transfer two tokens from the Series 400 to the Series 300,
perform the following steps:
* On the donating Series 400, execute the Donate_Tokens command,
specifying Full Session for the product:
Donate_Tokens (Product => "Full Session",
Donation => 2, -- number to
donate
Resulting_Remote_Count => 8, -- original 6 plus
2 new
Remote_Machine_Id => Id of the accepting
300,
Remote_Site => ">>SITE ID<<",
Response => "<PROFILE>");
The output generated by this command indicates that two tokens
have been donated, resulting in ten tokens remaining on the
current Series 400. It also supplies the completed
Accept_Tokens command to be run on the accepting system:
92/05/18 12:47:03 ::: [Donate_Tokens ("Full Session", 2, 8,
345678,
92/05/18 12:47:03 ... "XYZ000001", "<PROFILE>")].
92/05/18 12:47:03 +++ Donation of 2 tokens for Full Session
has resulted
92/05/18 12:47:03 ... in 10 tokens.
92/05/18 12:47:03 +++ Running Snapshot daemon.
Run the following on the remote machine:
Accept_Tokens (Product => "Full Session",
Donation => 2,
Resulting_Count => 8,
Code => "16A8AE0E1E838FB5");
92/05/18 12:47:15 ::: [end of Donate_Tokens].
* On the receiving Series 300, execute the Accept_Tokens command
generated in the previous step:
Accept_Tokens (Product => "Full_Session",
Donation => 2,
Resulting_Count => 8,
Code => "16A8AE0E1E838FB5",
Authorization => "",
Response => "<PROFILE>");
Upon acceptance of the token(s), the Environment automatically
changes the token kind to Login.
Note that the site ID must be the same on both the donating and
accepting machines. (You can use Show_Site to display the site ID
for a machine.) Note also that the Donate_Tokens and
36 May 1992 RATIONAL\f
Release D_12_6_5
Accept_Tokens commands must be run on the same day.
7.14.2. Token Changes to RXI
Beginning with D_12_6_5, the most recent release of RXI (10_9_0)
is delivered with the Environment. Although RXI must still be
separately installed, it is now authorized on all D_12_6_5
systems. Thus, product tokens are no longer required. This change
is in response to the evolution of RXI as one of the primary
access mechanisms to the Environment.
All problem reports concerning the improper consumption of tokens
by RXI now are considered closed. (PRS numbers 2604297-Rati-Pbk,
4123589-Blut-Jgp, 6398339-Blut-Med, and others)
For more information about RXI and D_12_6_5, see section 6.6.1.
7.15. Miscellaneous Changes to System Management
You now can set the timeout value for logging in through the
console command interpreter as part of machine initialization.
The default setting is 60.0 (1 minute). To change the setting,
edit the specification for
!Machine.Initialization.Rational.Servers in either of the
following ways:
* Change the value for the Console_Timeout paramater directly
* Insert a notation such as the following at the end of the
specification:
--| Parameter Console_Timeout => "2 * 60.0"
The new value takes effect the next time you reboot your machine.
The !Machine.Initization.Rational.Terminals procedure now
generates messages that properly reflect the parameters of the
Terminal.Set_Login_Disabled procedure, which is called by
Rational.Terminals. (PRS number 6242437-Blut-Vo)
A problem has been fixed in which the software flow control on
port 16 failed for Series 300C, 300S, 400C, and 400S systems.
(PRS numbers 9123690-0164-4 and 9123690-0165-8 and CSR number

Procedure Log_Reader.Load_Logs has been fixed so that it no
longer loads the error logs for the current day unless the
current day is between Start_Time and Stop_Time. The full
pathname for Load_Logs is
!Tools.System_Availability'Spec_View.Units.Log_Reader.Load_Logs.

certain types of invalid data. (PRS number 9123690-0152-5 and CSR
number 4741)
The comments in the specification for the
System_Utilities.Get_Board_Info function have been improved. In
particular, they now explain that board number zero (0) is IOA
ONLY in a Series 100 and that the number one (1) board is
SYS/IOC, which is the SYSBUS board for a Series 100 and the IOC
board for a Series 200, 300, or 400. For additional information,
see package System_Utilities in the updated System Management
Utilities book (Volume 10 of the ERM) or in online help. (PRS
numbers 9123690-0155-0 and 9123690-0155-1)
The Check_Universe_Acls procedure has been fixed so that it now
reports the correct access information for
!Machine.Initialization. The full pathname for
Check_Universe_Acls is
!Commands.System_Maintenance'Spec_View.Units.Check_Universe_Acls.
(PRS number 9176782-Gato-Gbd)
The directory daemon has been enhanced to perform more
consistency checking. Whenever a potential problem is detected,
the directory daemon now attempts to log a meaningful error
message and to proceed with the collection.
A problem has been fixed in which the directory manager sometimes
would detect an inconsistency erroneously when the version of an
object was being changed (that is, when an existing object was
being edited). This error would cause the following to be logged
in the system's error log:
Directory inconsistency exception in Object_Perform
Calling task (16#xxxxxxx#) will be stopped in wait service
(CSR numbers 5260 and 5261)
7.16. Changes to CMVC
The Cmvc.Initial procedure has been fixed so that when it is used
to create a new path in an existing subsystem, it no longer looks
at the System_Object_Type and Create_Load_View parameters unless
they are needed. Now Cmvc.Initial will ignore the default value
of the System_Object_Type parameter if the subsystem already
exists. If the subsystem exists and is either a Combined or
System subsystem, Cmvc.Initial will ignore the Create_Load_View
parameter because there is no choice of which kind of view to
create. (PRS number 7311575-Wash-Jim)
Cmvc.Copy, Make_Path, Make_Subpath, and Make_Spec_View now accept
a single space as the null string in the View_To_Import
parameter. Furthermore, log messages have been corrected so that
if an invalid value is entered for the View_To_Import, the
resulting message now includes the closing parenthesis. (PRS

Number 2809652-Clem-Jim)
Cmvc.Copy, Make_Path, Make_Subpath, Release, and Make_Spec_View
now properly copy Ada units from any directory in the subsystem,
not just those units in the Units directory. In particular for
Make_Spec_View, these sibling directories are treated like the
Units directory and only those items specified in the
State.Exports file are copied. This file is resolved in the
context of the Units directory; to include a unit outside this
directory you must provide an appropriate relative pathname-for
example, ^.Subdirectory_Name.Simple_Name-or a fully qualified
pathname. (PRS numbers 0-0358-2 and 9123690-0156-6 and CSR number
4971)
To create objects in a world or subsystem view, you now need only
Create access to that world or view. This change fixes a problem
introduced in D_12_5_0 in which Owner access was required. (PRS
numbers 9123690-0171-3 and CSR number 5841)
7.17. Update to !Tools.Math_Support
An update to the !Tools.Math_Support subsystem is included in the
D_12_6_5 release.
* In package Generic_Primitive_Functions:
- The Scale function has been corrected for very large and
very small scales.
- The Remainder function has been improved in cases where
arguments are several orders of magnitude apart.
- The Truncate function has been simplified.
* The implementation of package Generic_Elementary_Functions has
been replaced by a package with higher accuracy. The new
implementation was developed by Peter Tang and Kenneth Dritz,
from the Argonne National Laboratory, with minor adjustments
for the R1000. This change fixes several errors in domain
checking and a major error in the code for Tangent.

7.18. Miscellaneous Changes
7.18.1. Change to Library_Object_Editor
The specification for procedure
!Tools.Library_Object_Editor.Display has been changed to match
the Environment's implementation. In particular, the In_Place

parameter has been added to the procedure's specification:
procedure Display (Library : Directory.Object;
Selection : Directory.Object :=
Directory.Nil;
In_Place : Boolean := False;
Force_Redraw : Boolean := False);
The In_Place parameter specifies whether the current window frame
should be used. The default is False.
7.18.2. Change to Code_Segment_Object_Editor
The specification to procedure
!Tools.Code_Segment_Object_Editor.Edit has been changed to match
the Environment's implementation. In particular, a parameter,
The_Offset, has been added:
procedure Edit (The_Segment : Integer;
The_Offset : Integer := 0;
In_Place : Boolean := False);
Treating a segment as a file, The_Offset allows "editing" from a
place other than the beginning of the segment.

Appendix A
Guide to Machine Initialization
D_12_5_0 changed the software that is automatically executed by
the Environment during the boot process. These changes apply to
D_12_5_0 and all subsequent releases (including D_12_6_5). In
particular, the software was reorganized to make it easier to:
* Install layered products
* Distinguish Rational-specific, site-specific, and
machine-specific customizations
* Configure a network of printers for large sites
The following subsections describe the D_12_5_0 mechanisms for
initializing an R1000. Change bars indicate sections that have |
been added to this document since D_12_5_0; the initialization |
mechanisms themselves have not changed. You can read this |
document online by traversing to |
!Machine.Initialization.Guide_To_Machine_Initialization or by |
executing What.Does ("!Machine.Initialization"). |
See also the "Installation Procedure" for specific steps to
convert any existing initialization software to the D_12_5_0
mechanisms.
A.1. Overview
Each time an R1000 is booted, software is executed that
initializes layered products, sets various system parameters (for
example, disk-collection thresholds and snapshot intervals),
starts servers, enables terminals, and so on.
In Environment releases prior to D_12_5_0, the boot process
automatically executed !Machine.Initialize, which in turn
executed a family of procedures (with names of the form
!Machine.Initialize_@).
In D_12_5_0 and subsequent releases, !Machine.Initialize is no
longer used. Instead, all system-initialization software resides
in the world !Machine.Initialization, which is structured as
shown:
!Machine.Initialization : Library (World);
Local : Library (World);
Rational : Library (World);
Site : Library (World);

* The world Rational contains or references software that
initializes Rational products and provides standard settings
for many system parameters. Users should not modify the
objects in this world.
* The worlds Site and Local provide a place for system managers
to put objects that customize the initialization process. Such
objects can be used to override various standard system
parameter settings, to initialize customer-written
applications, and to specify terminal and printer
configurations:
- The world Site is intended for customer-written objects
that are common to two or more machines at a given site.
- The world Local is intended for customer-written objects
that apply only to the current R1000.
The following subsections give more detail about these worlds.
A.1.1. World !Machine.Initialization.Rational
The Rational world contains objects supplied by Rational that
perform basic initialization services for the current R1000.
These objects include:
* Loaded main procedures that are executed by
!Machine.Initialization.Start whenever the system is booted.
* "_Start" files that reference procedures located elsewhere in
the Environment. These are text files whose names end with
_Start; the procedures they reference are executed by
!Machine.Initialization.Start.
On a typical system, this world contains objects such as the
following:
!Machine.Initialization.Rational : Library (World);
Clean_Machine_Temporary : C Load_Proc;
Cross_Compilers : C Load_Proc;
Design_Facilities : C Load_Proc;
Dtia : C Load_Proc;

* Perform cleanup and compaction
* Initialize the installed Rational products, such as CDFs, RDF,
Rational Networking, and so on
* Initialize servers, including the archive and FTP servers
* Set standard values for various system parameters, such as the
medium-term scheduler, snapshot intervals and warnings,
disk-collection thresholds, and so on
* Initialize terminals and printers according to user-specified
requirements (given in files in the Site and Local worlds)
For more specific information, you can browse the comments in
each object in this world.
A.1.2. Worlds !Machine.Initialization.[Site,Local]
The Site and Local worlds are where system managers can create
objects to control sitewide or machine-specific initialization
and configuration. These objects may include:
* Ada procedures that supplement or override the basic
initialization services performed by objects in the Rational
world. All procedures in the Site and Local worlds are
executed by !Machine.Initialization.Start each time the system
is booted.
* "_Start" files that reference procedures located elsewhere in
the Environment. These are text files whose names end with
_Start; the procedures they reference are executed by
!Machine.Initialization.Start. Using a "_Start file" is
equivalent to calling Program.Run or Program.Run_Job to
execute the referenced procedure. (See section A.3.2.)
* Configuration files that tell the Environment how to enable
and configure ports for login and ports for printing. These
are text files that are read by two of the procedures executed
by !Machine.Initialization.Start. A default file for enabling
login ports is created in the Local world during installation.
(See sections A.4 and A.5.)
* Text files that tell the Environment how to initialize layered
products such as the Cross-Development Facility or the
Rational Design Facility. (See the comments in the
specifications of the Cross_Compilers and Design_Facilities
procedures in world !Machine.Initialization.Rational.)
At most sites, system managers will use the Site and/or Local
worlds as a place for procedures (or "_Start" files) that:
* Set password policy
RATIONAL May 1992 45\f
Rational Environment Release Information
* Set login limits
* Start server programs for site-specific networking, databases,
and applications (for example, a login monitor or network
security server)
At some sites, system managers may need to use these worlds for
procedures that:
* Provide nonstandard daemon settings-for example:
- The time at which daily and weekly clients run. (The
standard times are 3:00 a.m. for daily clients and 2:30
a.m. for weekly clients.)
- How often snapshots are taken. (The standard snapshot
interval is every 30 minutes.)
- Whether (and when) to send a snapshot warning, snapshot
start messages, and snapshot finish messages. (The standard
is to send a warning 20 seconds before the next snapshot
and to notify users only when the snapshot has finished.)
- The interval for daemon warnings. (The standard is to send
a warning 2 minutes before the daily clients begin.)
- Whether to send disk-collection threshold warnings. (The
standard is to warn users when collection thresholds have
been passed.)
- What kinds of system log messages appear on the operator
console. (The standard is to route only warning, problem,
and fatal messages to the operator console.)
- Whether clients should perform access-list compaction. (The
standard is for all relevant clients to perform access-list
compaction.)
* Provide customized disk-collection thresholds (see also
section A.3.4). Note, however, that values set by the
procedure in world Rational are calculated based on your disk
configuration and should be sufficient; see your Rational
technical representative if you want to use different
thresholds.
* Provide nonstandard medium-term scheduler settings. (Use the
Scheduler.Display command to see the standard settings.) Note,
however, that values set by the procedure in world Rational
should be sufficient; see your Rational technical
representative if you want to use different settings.

A.2. Setting Up the Site and Local Worlds
If you have a new R1000, you can use the following guidelines to
set up your Site and Local worlds:
1. Decide whether you need to provide any system customizations
such as those listed in section A.1.2. Create the appropriate
procedures and/or "_Start" files, using the hints given in
section A.3.
2. Inspect the default Terminal_Configuration file that was
created in the Local world during installation. This file
enables ports 235 through 249 for login. Edit this file if you
want to enable a different set of ports and/or specify further
connection or communication information; see section A.4.
3. Decide whether to implement a printer-configuration mechanism
to enable users to use !Commands.Abbreviations.Print and to
facilitate the use of networked printers. Create the
appropriate files; see section A.5.
4. If you have layered products such as the CDF or RDF, inspect
the comments in the specifications of the Cross_Compilers and
Design_Facilities procedures in world
!Machine.Initialization.Rational. Create any files required
for initializing these products (for example, a text file that
registers an RDF customization).
If you are upgrading from a release prior to D_12_5_0, the Local
world will already contain several objects that contain
customizations:
* A Terminal_Configuration file is created automatically in the
Local world, enabling the same set of ports that were enabled
at the time of installation. This file also preserves any
nondefault communication characteristics that were in effect
for RS232 ports.
* The !Machine.Initialize_Site procedure is automatically moved
into the Local world, as described in the "Installation
Procedure."
After your R1000 has been upgraded to D_12_5_0 or a more recent
release, you can use the following guidelines to set up your Site
and Local worlds:
1. Inspect the Initialize_Site procedure that has been copied
into the Local world during installation. Edit this procedure
to preserve any system customizations that are still
appropriate. You may want to split this procedure into
separate procedures and move appropriate procedures into the
Site world. See the "Installation Procedure" for specific
recommendations for handling this procedure. See also section
A.3 for information about initialization procedures and
"_Start" files.
RATIONAL May 1992 47\f

2. Inspect the default Terminal_Configuration file that was
created in the Local world during installation. Edit this file
if you want to enable a different set of ports and/or specify
further connection or communication information; see section
A.4.
3. Decide whether to implement a printer-configuration mechanism
to enable users to use !Commands.Abbreviations.Print and to
facilitate the use of networked printers. Create the
appropriate files; see section A.5.
4. If you have layered products such as the CDF or RDF, inspect
the comments in the specifications of the Cross_Compilers and
Design_Facilities procedures in world
!Machine.Initialization.Rational. Create any files required
for initializing these products (for example, a text file that
registers an RDF customization).
A.3. Hints for Implementing System Customizations
This section provides information about:
* Writing customized initialization procedures in the Site and
Local worlds; see section A.3.1.
* Writing "_Start" files that reference procedures that reside
in other Environment libraries; see section A.3.2.
* Controlling the order in which the customized initialization
procedures and the "_Start" files are processed by the Start
procedure; see section A.3.3.
* Customizing disk-collection thresholds; see section A.3.4.
A.3.1. Writing Customized Initialization Procedures
You can write procedures in the Site or Local worlds to implement
system customizations such as password policies, system daemon
settings, and so on. All procedures that appear in these worlds
are executed by the Start procedure each time the R1000 boots.
Customized initialization procedures can contain calls to
procedures in various standard Environment packages. Some useful
packages include:
* Package Daemon, which contains procedures that schedule
clients and warnings
* Package Operator, which contains procedures that set password
policy and login limits
* Package Scheduler, which contains procedures that control the
medium-term scheduler
48 May 1992 RATIONAL\f
Release D_12_6_5
* Package Program, which contains procedures that execute other
programs
Note that:
* You do not have to provide initialization procedures for
configuring login ports and printer ports; it is recommended
that you use configuration files instead (see sections A.4 and
A.5).
* You do not have to write an initialization procedure "from
scratch" for customizing disk-collection thresholds; if you
must customize these thresholds, it is recommended that you
edit the sample initialization procedure provided in the Local
world (see section A.3.4).
When writing customized initialization procedures:
* You can create separate procedures or put all calls in a
single procedure. Separate procedures take longer to execute
but make it easier to see what operations are being performed.
* You must not duplicate procedure names across the Rational,
Site, and Local worlds.
* You can specify the relative execution order of procedures
using annotations (see section A.3.3).
A.3.2. Using "_Start" Files to Reference Initialization
Procedures
As an alternative to writing procedures directly in the Site and
Local worlds, you can create "_Start" files in one or both worlds
to reference customized initialization procedures that reside
elsewhere in the Environment. "_Start" files are processed by the
Start procedure each time the R1000 boots, and the procedures
they reference are executed.
When writing "_Start" files:
* You must choose filenames that use the _Start suffix.
* You must not duplicate filenames across the Rational, Site,
and Local worlds.
* You must use annotations to reference the procedure to be
executed, as illustrated below.
* You may use annotations to control the order in which the
Start procedure executes the referenced procedures (see
section A.3.3).
Referencing a procedure in a world or directory: A "_Start" file
with the following contents illustrates the basic set of
RATIONAL May 1992 49\f
Rational Environment Release Information
annotations required to reference a procedure that resides in an
Environment world or directory:
--|Procedure_Name Initialize_Routine
--|Procedure_Context !Commands.Example
--|Parameters Notify => "manager",
--|Parameters Effort_Only => False
* The --|Procedure_Name annotation specifies the name of the
referenced procedure. If the procedure resides directly in a
library, you supply the procedure's simple name; if it resides
in a package, supply the name in the form
Package_Name.Procedure_Name.
* The --|Procedure_Context annotation specifies the Environment
world or directory that contains the referenced procedure.
* Each of the --|Parameters annotations specifies the value to
be used for one of the procedure's parameters. Note that
string values must be enclosed in quotation marks, and commas
must be included to separate multiple parameters.
Referencing a procedure in a subsystem: A "_Start" file with the
following contents illustrates how to reference a procedure that
resides in an Environment subsystem. Note that you must replace
the --|Procedure_Context annotation with the --|Subsystem and
(optional) --|Activity annotations:
--|Procedure_Name Excelan_Boot_Server
--|Subsystem !Targets.Implementation.Motorola_68k_Download
--|Activity !Machine.Release.Current.Activity
--|No_Wait
* The --|Subsystem annotation specifies the name of the
subsystem that contains the procedure. (When this annotation
is specified, the --|Procedure_Context annotation is ignored.)
* The --|Activity annotation specifies the activity to be used
to obtain the view name and construct the full pathname of the
procedure. If you omit this annotation,
!Machine.Release.Current.Activity is used.
* Note that Excelan_Boot_Server is a parameterless procedure;
otherwise, one or more --|Parameters annotations would be
present.
* The --|No_Wait annotation permits concurrent execution (see
section A.3.3). This annotation is present because this
procedure starts a server.
Specifying further information: "_Start" files may also contain
annotations that control the order in which the Start procedure
will execute the referenced procedures. See section A.3.3.
50 May 1992 RATIONAL\f
Release D_12_6_5
Using a "_Start" file is equivalent to executing the referenced
procedure via Program.Run_Job or Program.Run. See the comments in
the specification of !Machine.Initialization.Start for additional
annotations that specify the equivalent of the Options parameter
in the Program.Run_Job procedure and the Context parameter in the
Program.Run and Program.Run_Job procedures.
A.3.3. Controlling the Order of Execution
You can specify the relative execution order of all
initialization procedures (including those referenced in "_Start"
files). To do this, you include annotations in the appropriate
procedure specifications or "_Start" files:
* To specify that procedure A cannot run until procedure B has
finished, you include the annotation --|Prerequisite B in the
specification of procedure A (or in the "_Start" file that
references procedure A).
If procedure B is referenced in a "_Start" file, you specify
the filename as the annotation's argument: --|Prerequisite
B_Start.
Note that the argument of this annotation is a simple name and
that all three worlds (Rational, Local, and Site) are searched
for that simple name. Therefore, simple names must be unique
across these three worlds if you want to use this annotation.
* To specify that procedure A must finish before any other
procedure can start executing, you include the annotation
--|Wait in the specification of procedure A (or in the
"_Start" file that references procedure A).
Using this annotation is equivalent to executing procedure A
using Program.Run.
* To specify that procedure A is to execute as a separate job
concurrent with other procedures, you include the annotation
--|No_Wait in the specification of procedure A (or in the
"_Start" file that references procedure A).
Using this annotation is equivalent to executing procedure A
using Program.Run_Job.
If none of the annotations listed above are present in a given
procedure or "_Start" file, the --|Wait annotation is assumed.
That is, procedures are executed sequentially unless told
otherwise.
If a circular dependency results from a combination of
annotations, it will be reported and ignored, so that each
procedure will run.
RATIONAL May 1992 51\f
Rational Environment Release Information
Note that you can execute the Start command with the Effort_Only
parameter set to True to test the execution order that results
from your annotations.
See the comments in the specification of the
!Machine.Initialization.Start procedure for a complete
description of annotation usage, along with examples.
A.3.4. Customizing Disk-Collection Thresholds
You can customize the disk-collection thresholds for the
particular needs of your site. To implement a change in your
disk-collection thresholds:
1. Create an empty Ada unit in the Local world.
2. Copy the contents of the
!Machine.Initialization.Local.Local_Gc_Thresholds_Sample file
into the empty Ada unit.
3. In the Ada unit, edit the Thresholds1 and Thresholds2 arrays
to specify the desired thresholds.
4. Promote the Ada unit.
Note, however, that values set by the procedure in world Rational
are calculated based on your disk configuration and should be
sufficient; see your Rational technical representative if you
want to use different thresholds.
A.4. Enabling and Configuring Login Ports
D_12_5_0 and subsequent releases provide a file-driven mechanism
in !Machine.Initialization for enabling and configuring ports for
login.
At the very least, you must ensure that this mechanism has enough
information to enable the desired login ports (see section
A.4.1). In addition, you may optionally use this mechanism to
specify:
* Connection and terminal-type characteristics for Telnet and
RS232 ports, such as logoff on disconnect, disconnect on
logoff, and so on
* Communication characteristics for RS232 ports, such as flow
control, parity, and so on
Such information is specified using the options described in
section A.4.4.
52 May 1992 RATIONAL\f
Release D_12_6_5
A.4.1. Enabling Ports for Login
Ports for terminal devices must be enabled for login each time an
R1000 boots. Accordingly, the !Machine.Initialization.Start
procedure calls a procedure called Terminals in the Rational
world. This procedure in turn consults a file called
Terminal_Configuration in the Local world to determine which
ports to enable for login. This file-driven mechanism takes the
place of a procedure such as !Machine.Initialize_Terminals, which
enables terminals through calls to the Operator.Enable_Terminal
procedure.
The Terminal_Configuration file is created automatically in the
Local world during installation:
* On a new machine, a Terminal_Configuration file is created
that enables ports 235 through 249 for login.
* On an R1000 that is being upgraded from a previous Environment
release, the Terminal_Configuration file contains entries for
the same set of ports that were enabled at the time of
installation. (This file also preserves any nondefault
communication characteristics that were in effect for RS232
ports; see section A.4.4.)
You can edit the Terminal_Configuration file at any time to
change which ports are enabled. The changes take effect the next
time you boot the R1000. Alternatively, you can execute the
Rational.Terminals procedure to make the changes take effect
without booting the R1000. Note that you must keep the
Terminal_Configuration file in the Local world, even if you want
to enable the same ports on all machines at a given site.
Following is a sample Terminal_Configuration file containing
basic enabling information:
16 => (Enable)
224 .. 249 => (Enable)
-- Ports 250 and 251 are for printers; disable them for login
250..251 => (Login_Disabled)
As shown, the Terminal_Configuration file consists of:
* Comments preceded with Ada comment notation (--)
* Entries of the general form: Port_Range => (Options), where:
- Port_Range can be a single port number or a range of port
numbers
- Options must be enclosed in parentheses
The options that pertain to enabling and disabling ports are
summarized in Table A-1.
RATIONAL May 1992 53\f
Rational Environment Release Information
Table A-1 Options for Enabling and Disabling Ports
------------------------------------------------------------
| | |
| Option | Description |
------------------------------------------------------------
| | |
|Enable |When specified for a given port, enables the |
| |port for login. Note that the port cannot |
| |subsequently be enabled for any other device, |
| |such as a printer. |
------------------------------------------------------------
| | |
|Login_ |When specified for a given port, prevents the |
|Disabled |port from being enabled for login-for example, |
| |by subsequent usage of the |
| |Operator.Enable_Terminal command. Note that the|
| |port can subsequently be enabled for other |
| |devices, such as printers. |
------------------------------------------------------------
| | |
|Disable |When specified for a given port, disables the |
| |port for all devices. Note that the port can |
| |subsequently be enabled for any device, |
| |including login. Specifying this option is |
| |equivalent to having no entry for the port in |
| |the file. |
------------------------------------------------------------
Port 16 is always enabled for login, regardless of whether an
entry exists for it. An entry for port 16 is included in the
automatically created Terminal_Configuration file for
explicitness.
Do not assign the Enable option to any port that you plan to
enable for a printer or other device (such as a CDF). Instead,
you can assign the Login_Disabled option or the Disable option to
those ports, or you can simply omit entries for them from the
file. Assigning the Login_Disabled option is recommended if you
want to ensure that printer ports cannot be enabled for login
even if the print spooler is killed.
A.4.2. Customizing Port Characteristics
You can add information to the Terminal_Configuration file to
specify connection characteristics for RS232 ports and
communication characteristics for RS232 and Telnet ports. Such
information is specified through the options listed in section
A.4.4.
54 May 1992 RATIONAL\f
Release D_12_6_5
The simplest way to specify multiple options is to assign them
directly to a port or range of ports:
* Multiple options in a single entry must be enclosed in
parentheses.
* Multiple options must be separated by commas.
* The options can extend over several lines, although the entry
itself must start on a new line.
For example, the following entry assigns several connection
characteristics to ports 224..249 and then enables those ports:
224..249 => (Logoff_On_Disconnect,
Disconnect_On_Logoff,
Enable)
You can organize recurrent sets of options and improve
readability in the Terminal_Configuration file by defining an
abbreviation for each set of options and then assigning each
abbreviation to a port or range of ports:
* Abbreviation entries are of the general form Abbreviation =
Options. Note that the equals sign (=) is used to define
abbreviations; the => symbol is used for port assignment.
* Existing abbreviations can be nested in the definition of new
abbreviations.
For example, the following entries create the abbreviations
User_Ports and Telnet_Ports, assigning the Telnet_Ports
abbreviation to ports 224..249:
-- Port settings for user login ports
User_Ports = (Logoff_On_Disconnect, Disconnect_On_Logoff)
-- Port settings for Telnet ports
Telnet_Ports = (Terminal_Type => Xrterm, User_Ports)
224..249 => (Telnet_Ports, Enable)
When adding entries to a Terminal_Configuration file, bear in
mind that:
* Nondefault communication characteristics for RS232 ports must
be set each time an R1000 boots. Consequently, if a port is to
have nondefault values for any of the options listed in Table
A-4, you must include these options in the entry for that
port. Omitting an option causes its default value to be set.
* Connection and terminal-type characteristics persist across
boots, retaining the last values that were set for them. Thus,
in principle, the options listed in Tables A-2 and A-3 need to
be set only once and then can be omitted from the
RATIONAL May 1992 55\f
Rational Environment Release Information
Terminal_Configuration file. However, you may choose to
include values for these options in the file to ensure that
booting the system resets them to the proper values in case
they had been changed.
* The options for each port are set in the order in which they
are assigned in the Terminal_Configuration file. Similarly,
the options in an abbreviation are set in the order in which
they are declared. If a single port number is included in the
ranges of more than one entry, that port takes the options of
the last entry in which it appears.
A.4.3. A Sample Terminal_Configuration File
The following sample file shows how a system manager can use
abbreviations to organize port information meaningfully. Note
that a number of connection options have been explicitly set to
ensure that booting the system sets them to a known value. Note
also that specifying the Disable option for the printer ports is
not absolutely necessary; however, specifying this option ensures
that no previous entry in the file had inadvertently enabled
these ports.

A.5. Configuring Printers
D_12_5_0 and subsequent releases provide a file-driven mechanism
in !Machine.Initialization for configuring a group of networked
and/or local printers. This mechanism allows you to define a
printer name for each printer on the network and to specify how
each printer is to be accessed. Furthermore, you can also
associate a printer name with each user, so that when a given
user enters the Print command (that is,
!Commands.Abbreviations.Print), the print job will be sent by
default to the device that is defined by the associated printer
name.
This file-driven mechanism automatically adds the specified
devices to the appropriate R1000s, creates the necessary print
classes on the appropriate R1000s, and associates each class with
the specified device, thereby creating print queues. Thus, when
you use the file-driven mechanism, you do not need to use
procedures from package Queue (such as Add, Create, Enable, and
Register) to do these things.
Existing sites can choose whether to use this file-driven
mechanism or to continue using procedures from package Queue to
configure printers. However, because the file-driven mechanism
combines class and machine information, it is recommended that
large sites with multiple networked printers use the file-driven
!Machine.Initialization mechanism. Small sites with few printers
60 May 1992 RATIONAL\f
Release D_12_6_5
connected directly to R1000s may want to continue using package
Queue. Sites that want to create a single class with multiple |
devices should also use package Queue. |
Note that the printer configuration (set either through commands |
in package Queue or through the file-driven mechanism) applies to |
both the Queue.Print and Abbreviations.Print commands. The |
ability to associate printer names with usernames is specific to |
the Abbreviations.Print command. |
A.5.1. Where to Specify Printer Information
Each time an R1000 boots, the !Machine.Initialization.Start
procedure calls a procedure called Printers in the Rational
world. This procedure initializes the print spooler on that R1000
based on the information in the following user-created files:
* !Machine.Initialization.Site.Printer_Configuration, which
defines a printer name for each of the devices available on
the network and specifies how each device is to be accessed. A
copy of this file must exist on all R1000s from which users
will enter the Print command and on all R1000s that will
handle print requests for the specified devices.
* !Machine.Initialization.Local.Printer_Configuration, which
defines additional printer names for additional devices
intended only for users of the current R1000.
* !Machine.Initialization.Local.User_Printer_Map, which
associates a default printer name with individual users on the
current R1000. When a user executes the Print command with the
default Printer parameter, the command looks up the user's
name and sends the print request to the corresponding printer.
At a minimum, the Print command requires that one
Printer_Configuration file exist in either the Site or Local
world. If no User_Printer_Map file exists (or if the file exists
but contains no entry for a particular user), the Print command
uses the first printer name defined in the
Site.Printer_Configuration file. If this file doesn't exist, the
first printer name defined in the Local.Printer_Configuration
file is used.
The classes and devices specified in the Printer_Configuration |
files are created when the Printers procedure (that is, |
!Machine.Initialization.Rational.Printers) is executed (normally, |
during machine initialization). The Printers procedure also |
associates usernames with the appropriate printer information. Be |
aware that whenever information is changed in any of the files |
listed above, the Printers procedure must be run in order to |
update the information. |
If you choose not to create any of these files, you will have to:
RATIONAL May 1992 61\f
Rational Environment Release Information
* Create an initialization procedure (in either the Site or
Local world) that uses package Queue to create print queues
each time the system boots.
* Either:
- Use the Queue.Print command instead of the
!Commands.Abbreviations.Print command.
- Use the !Commands.Abbreviations.Print command, but
explicitly specify the class name for the Printer
parameter.
A.5.2. Adding Entries to a Printer_Configuration File
During installation, an empty Printer_Configuration file is
created in the Local world. After installation, you can:
* Add entries to this file to enable the use of the Print
command.
* Move this file (or create an additional file called
Printer_Configuration) in the Site world, if you need to
define sitewide printer information.
Each entry in a Printer_Configuration file defines a printer name
and specifies the characteristics of the device it represents.
Each entry must start on a new line, but the information can
extend over several lines and can include single and in-line
comments. For readability, the entries are often formatted like
command parameters.
Each entry has the general form:
Printer_Name => (Device_Type => Device_Info,
Other_Device_Characteristics,
Laser_Comm => Boolean,
Reverse_Output_Pages => Boolean,
On_Node => R1000_Name)
where:
* Printer_Name is the name by which you want to refer to a given
| device in a Print command. Printer_Name must be a legal Ada
| simple name.
* Device_Type is one of the following four kinds of printer
devices:
- Direct, which specifies a printer connected to an R1000 via
direct line.
62 May 1992 RATIONAL\f
Release D_12_6_5
- Telnet, which specifies a printer connected to an R1000 via
Telnet.
- File, which specifies a file on an R1000 in which
print-spooler output is collected. Subsequent processing is
required to get this output printed.
- Workstation, which specifies a directory on a remote
workstation to which print requests are sent. Such requests
are sent via FTP as individual files; from the remote
directory, they can be printed using the workstation's
print tools.
* Device_Info is further information about the device you
specified. The information depends on the type of device
specified (see the paragraphs below).
* Other_Device_Characteristics are additional entry elements,
separated by commas, that give further information about the
chosen device (see the paragraphs below).
* The Laser_Comm option, when True, specifies that printing will
be done on a laser printer. Omitting this option implies that
printing will be done on a line printer.
For Direct and Telnet devices, setting Laser_Comm to True
specifies that a laser printer is connected; for File and
Workstation devices, setting Laser_Comm to True specifies that
the collected print requests will eventually be printed on a
laser printer.
* The Reverse_Output_Pages option allows you to adjust the order
in which pages are spooled to accommodate the way your printer
stacks pages in its output tray. This option applies only if
the Laser_Comm option is set to True.
- Setting Reverse_Output_Pages to True causes the print
spooler to reverse the order of output pages, so that the
last logical page is printed first. Omitting this option is
equivalent to specifying True.
- Setting Reverse_Output_Pages to False causes the print
spooler to keep the pages of output in the order in which
they appear in the source file.
* The On_Node option specifies the network name of the R1000
that contains the print spooler for the device. Omitting this
option is equivalent to specifying the name of the current
R1000.
The following paragraphs describe printer-configuration file
entries for each of the four kinds of devices. (See also the
comments in the specification of
!Machine.Initialization.Rational.Printers.)

A.5.3. Specifying a Directly Connected Printer
To specify a printer connected to an R1000 via direct line, you
specify an entry of the following general form:
Printer_Name => (Direct => Protocol,
Device => Terminal_N,
Laser_Comm => Boolean,
Reverse_Output_Pages => Boolean,
On_Node => R1000_Name)
where:
* Protocol specifies the printer flow control and can be either
Xon_Xoff or Dtr. See the printer manual for details.
* Terminal_N represents the RS232C port to which the printer is
connected (N is the port number). The specified port must not
be enabled for login in the Local.Terminal_Configuration file.
* The Laser_Comm option, when True, specifies that a laser
printer is connected and enables a two-way
printer-communication protocol. Omitting the option is
equivalent to specifying False, which means that a line
printer is connected.
* The Reverse_Output_Pages option allows you to adjust the order
in which pages are spooled to accommodate the way your printer
stacks pages in its output tray, as described in section
A.5.2. This option applies only if Laser_Comm is set to True.
* The On_Node option specifies the network name of the R1000 to
which the printer is directly connected. Omitting this option
is equivalent to specifying the name of the current R1000.
The following entry creates a printer name called Lp, which
represents a line printer that is directly connected to port 30
of an R1000 called Jazmo:
-- Line printer connected to Jazmo
Lp => (Direct => Xon_Xoff,
Device => Terminal_30,
On_Node => Jazmo)
A.5.4. Specifying a Networked Printer
To specify a printer connected to an R1000 via Telnet, you
specify an entry of the following general form:
Printer_Name => (Telnet => Host_Name,
Device => Terminal_N,
Laser_Comm => Boolean,
Reverse_Output_Pages => Boolean,
On_Node => R1000_Name)
64 May 1992 RATIONAL\f
Release D_12_6_5
where:
* Host_Name is the network name of the printer.
* Terminal_N represents the Telnet port to which the printer is
connected (N is the port number). The specified port must not
be enabled for login in the Local.Terminal_Configuration file.
* The Laser_Comm option, when True, specifies that a laser
printer is connected and enables a two-way
printer-communication protocol. Omitting the option is
equivalent to specifying False, which means that a line
printer is connected.
* The Reverse_Output_Pages option allows you to adjust the order
in which pages are spooled to accommodate the way your printer
stacks pages in its output tray, as described in section
A.5.2. This option applies only if Laser_Comm is set to True.
* The On_Node option specifies the network name of the R1000 to
which the printer is connected via Telnet. Omitting this
option is equivalent to specifying the name of the current
R1000.
The following entry creates the printer name Dlaser, which
represents a laser printer that is connected via Telnet to port
226 of an R1000 called Roget. Because of the way this printer
stacks its output, print requests are spooled to this device with
their pages in ascending (rather than reversed) order:
-- Documentation's laser printer
Dlaser => (Telnet => Doc_Laser,
Device => Terminal_226,
Laser_Comm,
Reverse_Output_Pages => False,
On_Node => Roget)
A.5.5. Specifying an Environment File
To specify a file in which to collect print-spooler output, you
specify an entry of the following general form:
Printer_Name => (File => Environment_Pathname,
Laser_Comm => Boolean,
Reverse_Output_Pages => Boolean,
On_Node => R1000_Name)
where:
* Environment_Pathname specifies the file to which output is
written. The pathname must name a file that exists on the
R1000 named by On_Node. Note that the group Spooler must have
access to the specified file.
RATIONAL May 1992 65\f
Rational Environment Release Information
* The Laser_Comm option, when True, specifies that the collected
print requests will eventually be printed on a laser printer.
Omitting the option is equivalent to specifying False, which
means that a line printer will be used.
* The Reverse_Output_Pages option allows you to adjust the order
in which pages are spooled to accommodate the way your printer
stacks pages in its output tray, as described in section
A.5.2. This option applies only if Laser_Comm is set to True.
* The On_Node option specifies the network name of the R1000 on
which the file is located. Omitting this option is equivalent
to specifying the name of the current R1000.
The following entry creates the printer name Hold, which
represents a file on an R1000 called Logo. Low-priority print
requests are sent to this file, where they are held until someone
prints the file using the Print command (specifying a printer
name that represents a connected printer):
-- Place to hold large requests until printers are free in the
evening
Hold => (File => !Machine.Queues.Local.Held_Print_Requests,
On_Node => Logo)
A.5.6. Specifying a Workstation Directory
To specify a directory on a workstation to which print requests
are sent, you specify an entry of the following general form:
Printer_Name => (Workstation => Host_Name,
Path => Directory_Name,
Laser_Comm => Boolean,
Suffix => String,
Reverse_Output_Pages => Boolean,
On_Node => R1000_Name)
where:
* Host_Name is the network name of the workstation to which the
files will be transferred.
* Directory_Name is the pathname of the workstation directory
into which the files will be transferred. The directory
pathname must have syntax appropriate to the workstation and
must have trailing punctuation that permits the name of the
transferred print-request file to be appended.
* The Laser_Comm option, when True, specifies that the collected
print requests will eventually be printed on a laser printer.
Omitting the option is equivalent to specifying False, which
means that a line printer will be used.
66 May 1992 RATIONAL\f
Release D_12_6_5
* The Suffix option allows you to specify a string to be
appended to the filenames that are created on the workstation.
Omitting this option causes no suffix to be appended to the
filenames. The specified suffix can be used by print tools as
a way of identifying which files to print. This is useful when
several printer names send files to the same directory.
* The Reverse_Output_Pages option allows you to adjust the order
in which pages are spooled to accommodate the way your printer
stacks pages in its output tray, as described in section
A.5.2. This option applies only if Laser_Comm is set to True.
* The On_Node option specifies the network name of the R1000
whose print spooler handles the print requests. Omitting this
option is equivalent to specifying the name of the current
R1000.
In addition to creating an entry for each workstation in the |
Printer_Configuration files, you must also create a |
remote-passwords file, containing the username and password to be |
used for accessing each workstation. This remote-passwords file |
must be named Remote_Access and exist in the library |
!Machine.Queues.Ftp. (For information about remote-passwords |
files, see package Remote_Passwords in the Session and Job |
Management book of the Rational Environment Reference Manual.) |
When print requests are sent as files to a workstation, any FTP
messages are directed to a log file that is created in
!Machine.Queues.Ftp. This log file is automatically cleared after
each 100 print requests. Messages pertaining to creating print
classes and enabling devices are directed to the system error
log.
The following two entries create printer names Dc_Laser and
Dc_Lineprinter, both of which direct print requests to a
directory on a UNIX workstation called Enterprise. These print
requests, which are routed through the print spooler on an R1000
called Capitol, are sent as files with different suffixes,
depending on the printer name (_Lsr and _Lpt, respectively):
-- Laser printer attached to workstation in Washington, D.C.,
office;
-- spooled on R1000 called Capitol.
Dc_Laser => (Workstation => Enterprise,
Path => /usr/spool/ratqueue/,
Laser_Comm,
Suffix => _Lsr,
On_Node => Capitol)
-- Line printer attached to workstation in Washington, D.C.,
office;
-- spooled on R1000 called Capitol.

Appendix B
Diagnostic Crash Procedures
B.1. Introduction
The D_12_6_5 release includes enhancements to the process of
analyzing R1000 crashes. In particular:
* Much of the process has been automated so that the system will
capture as much information as possible and often reboot
automatically.
* A series of questions and menus have been added to the
diagnostic crash procedures, which:
- Capture system crash state
- Analyze system hardware
The instructions in this appendix supersede those in your System
Manager's Guide. For convenience, you may want to place a copy of
these procedures with your System Manager's Guide.
B.2. When Your System Crashes
Call the Rational Response Center whenever your R1000 fails. You
will be guided through the most appropriate parts of the
procedures below-in some cases through other undocumented steps
as well-to reach an effective and timely diagnosis of the
problem. For information about contacting the Rational Response
Center, see section B.12.
If your system crashes outside Rational's normal support hours,
follow one of the three options described below. These options
are listed in order, from most desirable to least desirable (in
terms of gathering information needed to determine why your
machine crashed and to prevent additional crashes):
* Wait and contact the Rational Response Center during normal
support hours (see section B.12).
* Gather diagnostic information about your system crash (by
following the diagnostic crash procedures in this appendix)
before you try to reboot the machine.
* Try to reboot the machine immediately without gathering
diagnostic information. Be aware that doing so may lengthen
the time it takes to isolate and resolve the problem.
RATIONAL May 1992 71\f
Rational Environment Release Information
B.3. Using These Diagnostic Crash Procedures
The instructions in this appendix are designed to help you
collect as much diagnostic information as possible about the
state of your machine at the time of a system crash. By following
these procedures, you will help shorten the time to diagnose and,
if necessary, repair your system.
These procedures are organized into sections roughly according to
the order in which you may need to perform them.
No matter why the system crashed, you should always capture
system-state information, as described in section B.4.
Then, if you experienced or are experiencing:
* A power failure, see section B.5.
* Overheating, see section B.6.
* The "connect modem" message, begin with section B.7.
* Any other failure message, begin with section B.8.
* Disk errors, begin with section B.8 and continue through
section B.10.
After executing the procedures in the following sections, fax or
e-mail the information you have gathered to the Rational Response
Center (see section B.12).
Note that when the R1000 CPU stops running, the I/O processor
queries all the boards to determine what caused it to stop. The
message given by the R1000 when it crashes names the board that
detected the specific check; therefore, the named board is not
necessarily the faulty part.
B.4. Saving Information about the System State
When your system fails, you should begin by saving information
about the system state.
1. Write down the crash information displayed on the operator
console. If this information has already scrolled off the
screen, go to step 2, below. In particular, write down the
machine check message (MC), crash reason (CR), trace (TR), and
any other messages (OM) displayed. A sample crash output is
shown below:

Was the R1000 still booting when it crashed?
Why was it booting?
* Was the Environment up at the time?
Was there anything abnormal about the way the Environment
was functioning?

What were users doing? Any unusual activities?
Were any daemons (snapshot, daily, or weekly) running?
Was a tape drive in use?
* Have there been any hardware, firmware, or software changes
to this R1000 within the past week?
* Have there been any problems with or modifications of the
network in the past week?
* What was the temperature in the computer room at the time
of the crash?
* Have there been any problems with the air conditioning
recently?
* Are there other computers (R1000s or not) in the same
building?
Did any of the other computers crash or have power or
environmental problems at the same time?
3. Use the crash reason message (displayed in reverse video below
the line of equal signs) to locate the appropriate recovery
process in section B.9.
B.5. Crash due to Power Failure
Note: A crash due to a power failure does not cause the system to
dial Rational through the system's internal modem, even when the
system is configured to do so for other types of crashes.
B.5.1. Indication of Power Failure
In most cases, a crash due to power failure is reported by the
following message in reverse video on the operator console:
Restarting system after loss of AC power
B.5.2. Recovering from Power Failure
When your system crashes because of a power failure:
1. If power to the system is still off, turn the system's power
keyswitch to OFF.
Turning the power keyswitch to OFF reduces the chance of
accidental damage to the R1000 when the source of power is
restored.
2. Before trying to restart the system, try to determine the
cause and extent of the power failure and to correct the
problem.
74 May 1992 RATIONAL\f
Release D_12_6_5
Determining the cause and extent of the power failure commonly
requires the aid of your site facilities personnel. If the
power failure affected your entire site, your site facilities
personnel should contact your local power company for further
information.
3. Restore power to the R1000 and turn the power keyswitch to ON.
4. After power has been restored, the system will do one of three
things, depending on its configuration:
* Boot automatically
* Begin booting and stop at the Interactive menu:
Options are:
1 => Change BOOT/CRASH/MAINTENANCE options
2 => Change IOP ENVIRONMENT configuration
3 => Enable manual crash debugging (experts only)
4 => Boot IOP, prompting for tape or disk
5 => Boot system
Enter option [Boot System]:
If the system stops at the Interactive menu, press
[#Return#]. The system will display the Crash menu.
* Begin booting and stop at the Crash menu:
Options are:
1 => Enter CLI
2 => Make a CRASHDUMP
3 => Run the FRU tests
4 => Boot DDC configuration
5 => Boot EEDB configuration
6 => Boot STANDARD configuration
Enter option [Boot STANDARD] :
If the system stops at the Crash menu, press [#Return#].
The system will continue booting.
5. If the system does not reboot properly, then:
A. Examine the operator console to see what messages are
displayed.
B. Contact the Rational Response Center (see section B.12).
B.6. Crash due to Overheating
Note: A crash due to overheating does not cause the system to
dial Rational through the system's internal modem (mounted on the
RATIONAL May 1992 75\f
Rational Environment Release Information
PCM card in the PCM unit), even when the system is configured to
do so for other types of crashes.
B.6.1. Indications of Overheating
In most cases, a crash due to overheating causes all of the front
panel lights to be off although the power switch is on.
You can determine if the failure is due to overheating by
examining the state of the LED overtemp indicator. On Series 200
and 300 systems, the overtemp indicator is on the power control
module (PCM) and can be viewed by opening the rear door of the
CPU cabinet. On a Series 400 system, the indicator is on the I/O
panel, visible by opening the front door of the cabinet. (See
your System Manager's Guide if you are unsure of the overtemp
indicator's location.)
Warning: Do not reach inside the CPU bay. Electric-shock hazards
are present inside the R1000 cabinets.
If the overtemp indicator is lit, this means that sensors in the
R1000 had detected that the temperature inside the cabinet was
too high and powered the system off.
B.6.2. Recovering from Overheating
1. Check the room temperature. Note that the room air temperature
must not exceed 85#F (29#C) while the R1000 is operating. (For
detailed environmental requirements, refer to the Rational
R1000 Development System: Site-Planning Guide for your
system.)
2. If the room temperature is correct, the problem might be a fan
failure inside the cabinet, clogged filters, or some other
problem. In this case:
A. Verify that the power keyswitch on the control panel is in
the Off position.
B. Contact the Rational Response Center for assistance (see
section B.12).
3. After the overheating condition has been corrected, power off
and restart the system by following the instructions in steps
3 through 5 of section B.5.2, above.
4. If the system does not reboot properly:
A. Examine the operator console to see what messages are
displayed.
B. Contact the Rational Response Center (see section B.12).
