TITLE: OpenVMS VMS73_LIBRTL-V0100 Alpha V7.3 LIBRTL ECO Summary

******************************************************************

                        OpenVMS Remedial Kit
                         Hold Notification

Date: 22-JAN-2002

Kit Name:VMS73_LIBRTL-V0100
Release Date: 19-DEC-2001
        

PROBLEM STATEMENT:

The LIBRTL.EXE image in the VMS73_LIBRTL-V0100 kit was taken from
an incorrect build. It does not correct the problems that are
outlined in the kit.

PROBLEM SYMPTOM:

Symptoms are varied and will most likely result in an access
violation with the C Runtime routines malloc and free.

WORKAROUND:

If the VMS73_lIBRTL-V0100 kit has been installed, the LIBRTL.EXE_OLD
image should be renamed to be the latest LIBRTL.EXE image on the
system. The system should then be rebooted.

ALTERNATIVE KIT:

There is no alternative kit. A new VMS73_LIBRTL-V0200 kit will be
issued with the appropriate images.

New Kit Date: 20-DEC-2001
Modification Date: Not Applicable
Modification Type: New Kit

NOTE: An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
 
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
 
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can
       be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

ECO KIT SUMMARY:

An ECO kit exists for LIBRTL on OpenVMs Alpha V7.3
This kit addresses the following problems:

PROBLEMS ADDRESSED IN VMS73_LIBRTL-V0100 KIT:

  o The new C compiler for V7.3 (Compaq C V6.2-008) generates
     different code for the __CMP_STORE_QUAD built-in. The old
     compiler (V5.7-006) generated a Memory Barrier (MB)
     instruction as part of this operation which the new compiler
     does not. The Memory Barrier is required for the LIB routines
     for proper synchronization, otherwise a packet being put on a
     free list may have an invalid flink when viewed from another
     processor.

          Images Affected: [SYSLIB]LIBRTL.EXE
                            [SYSLIB]LIBRTL_INSTRUMENTED.EXE

INSTALLATION NOTES:

This kit requires a system reboot. Compaq strongly recommends that
a reboot is performed immediately after kit installation to avoid
system instability

If you have other nodes in your OpenVMS cluster, they must also be
rebooted in order to make use of the new image(s). If it is not
possible or convenient to reboot the entire cluster at this time, a
rolling re-boot may be performed.

INSTALLATION INSTRUCTIONS:

Install this kit with the POLYCENTER Software installation utility
by logging into the SYSTEM account, and typing the following at the
DCL prompt:

     PRODUCT INSTALL VMS73_LIBRTL /SOURCE=[location of Kit]

The kit location may be a tape drive, CD, or a disk directory that
contains the kit.

Additional help on installing PCSI kits can be found by typing
HELP PRODUCT INSTALL at the system prompt

Special Installation Instructions:

  o Scripting of Answers to Installation Questions

     During installation, this kit will ask and require user
     response to several questions. If you wish to automate the
     installation of this kit and avoid having to provide responses
     to these questions, you must create a DCL command procedure
     that includes the following definitions and commands:

       - $ DEFINE/SYS NO_ASK$BACKUP TRUE

       - $ DEFINE/SYS NO_ASK$REBOOT TRUE

       - Add the following qualifiers to the PRODUCT INSTALL
          command and add that command to the DCL procedure.

          /PROD=DEC/BASE=AXPVMS/VER=V1.0

       - De-assign the logicals assigned

     For example, a sample command file to install the
     VMS73_LIBRTL-V0100 kit would be:

          $
          $ DEFINE/SYS NO_ASK$BACKUP TRUE
          $ DEFINE/SYS NO_ASK$REBOOT TRUE
          $!
          $ PROD INSTALL VMS73_LIBRTL/PROD=DEC/BASE=AXPVMS/VER=V1.0
          $!
          $ DEASSIGN/SYS NO_ASK$BACKUP
          $ DEASSIGN/SYS NO_ASK$REBOOT
          $!
          $ exit
