OpenVMS VMS731_PCSI-V0100 Alpha V7.3-1 PCSI ECO Summary
TITLE: OpenVMS VMS731_PCSI-V0100 Alpha V7.3-1 PCSI ECO Summary
 
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.pcsi-dcx_axpexe or
       kitname.pcsi-dcx_vaxexe, then it can be expanded by typing
       RUN kitname.pcsi-dcx_axpexe or kitname.pcsi-dcx_vaxexe.  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 System components on OpenVMS Alpha V7.3-1.  
This kit addresses the following problems:

NEW FUNCTIONALITY INCLUDED IN THE VMS731_PCSI-V0100 KIT

     o  This patch kit implements a new /RECOVERY_MODE qualifier.
        When installing a patch or full type kit in recovery mode, if
        the operation is terminated (either due to an error condition
        or by the user entering CTRL-C or CTRL-Y), any files that were
        added, modified, or deleted by the kit installation are
        restored to their state prior to the operation.  The
        /RECOVERY_MODE qualifier enables recovery mode for the PRODUCT
        INSTALL and PRODUCT RECONFIGURE commands.

        The /RECOVERY_MODE qualifier allows you to recover from a
        failed installation of any type of kit.  Once the operation
        completes, the recovery data is automatically deleted.

                           *** Note ***

        All current OpenVMS operating system patch kits support this
        new /RECOVERY_MODE capability.  However, operating system
        patch kits that are no longer current and/or some current
        layered product patch kits may not support /RECOVERY_MODE.  If
        such a kit is installed using the /RECOVERY_MODE qualifier
        PCSI may not be able to correctly perform a recovery, leaving
        your system in an inconsistent state.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE



     o  This patch kit gives the user the capability to uninstall
        (UNDO) patch kits for which recovery data has been saved.

        This capability is supported by the following new commands:

           o  PRODUCT INSTALL /SAVE_RECOVERY_DATA

           o  PRODUCT UNDO PATCH

           o  PRODUCT SHOW RECOVERY_DATA

           o  PRODUCT DELETE RECOVERY_DATA

        There are several constraints to using this functionality that
        the user should be aware of:

           -  A patch must be installed using the /SAVE_RECOVERY_DATA
              qualifier in order to create a recovery data set for use
              at the time the kit is uninstalled.  Each PRODUCT INSTALL
              /SAVE_RECOVERY_DATA command creates a separate recovery
              data set that will contain information about one or more
              patches.

           -  Patches can only be uninstalled in the reverse order in
              which they were installed.  You can "UNDO" the last patch
              installed, then the previous one, etc.

           -  Once there is recovery data on the system, if a patch kit
              is installed without the /SAVE_RECOVERY_DATA qualifier,
              recovery data for all patch kits that had been installed
              using the /SAVE_RECOVERY_DATA qualifier will be lost.
              However, the user will be notified by any patch
              installation that will delete recovery data and will be
              given the opportunity to cancel the installation before
              any data is deleted.

           -  Any installation of a non-patch kit, for example a layered
              product kit, will delete all recovery data sets that may
              have been created during previous patch installations.
              However, the user will be notified by any installation
              that will delete recovery data and will be given the
              opportunity to cancel the installation before any data is
              deleted.

           -  The PRODUCT UNDO PATCH command is not related to the
              PRODUCT REMOVE command that is used to uninstall full
              products.

           -  All current OpenVMS operating system patch kits support
              this new UNDO mode capability.  However, operating system
              patch kits that are no longer current and/or some current
              layered product patch kits may not support UNDO mode.  If
              such a kit is installed using the PRODUCT INSTALL
              /SAVE_RECOVERY_DATA command and then uninstalled using
              PRODUCT UNDO PATCH, your system may be left in an
              inconsistent state.


        Consult the on-line help text for more information about the
        patch removal capability.

     o  The PRODUCT SHOW OBJECT command has been enhanced to show the
        generation number associated with each file and module
        installed.  A generation number is a attribute of certain
        objects that is used by the POLYCENTER Software Installation
        utility to resolve conflicts when two or more products provide
        the same file or library module.  See the on-line help text
        for the PRODUCT SHOW OBJECT command to learn more about
        generation numbers.

                         [SYSLIB]PCSI$SHR.EXE

     o  The /FULL qualifier has been added to the PRODUCT LIST
        command.  This qualifier provides file size and other useful
        information about files in a product kit.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE


     o  The EXECUTE UPGRADE statement has been added to the product
        description language for creating product description files.
        This statement allows product kit developers to specify that a
        command procedure be executed only when the product is being
        upgraded.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE


     o  If a file or library module from a product kit being installed
        has the same generation number attribute as an object with the
        same name already installed by another product (or another
        patch for the same product), the file or module from the kit
        will be installed.  Previously, the file or module already
        installed was retained.  This change ensures that the
        re-installation of a full product or patch will cause objects
        from the kit to be re-copied to the system.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE


     o  The PRODUCT INSTALL command can operate on PCSI kits with a
        file type of .PCSI$COMPRESSED in a transparent manner.
        Compressed kits are encoded using a data compression technique
        that significantly reduces their file size.  When a compressed
        kit is installed, records are decompressed (expanded)
        on-the-fly so no additional disk space is required to store a
        decompressed version of the kit.  Full support for creating
        and manipulating compressed kits is expected to be available
        in the next release for OpenVMS Alpha.  This remedial kit
        enables the use of compressed kits when they become available
        in the future.

PROBLEMS ADDRESSED IN VMS731_PCSI-V0100 KIT

     o  In the following scenario, product database corruption will
        occur.  The corruption is caused by improper processing of a
        DIRECTORY statement in the product description file:

          1.  A full product is installed that explicitly creates
              directories [A] and [A.B.C]

          2.  A patch kit is then installed that explicitly creates
              directory [A.B]

          3.  The full product is upgraded


        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE



     o  Under certain conditions, the PRODUCT command aborts on
        deallocation of virtual memory.  This is most likely to occur
        when the destination device for an installation contains many
        access control lists.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE



     o  If during the execution of a PRODUCT INSTALL command, an
        attempt to spawn a subprocess fails or an attempt to create a
        detached subprocess fails, the primary error message is not
        reported - just a generic PCSI abort message is displayed.
        With this change, the primary error message is reported.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE


     o  Fix Various problems related to PRODUCT EXTRACT RELEASE_NOTES:

           o  Preserve the file name of a release notes file on
              extraction instead of giving it the name of
              DEFAULT.PCSI$RELEASE_NOTES.

           o  If there is more than one release notes file in a product
              kit, because they may be in different formats such as
              .TXT, .HTML, and PS, extract them as separate files
              instead of concatenating them.

           o  Support sequential files in VFC format as release notes.


        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE



     o  Many informational, warning, and error messages have been
        added or revised.

                         [SYSLIB]PCSI$SHR.EXE


     o  An ACCVIO occurs when multiple patch kits are installed and
        two or more of these kits provide the same file with the same
        generation number.

        Images Affected: [SYSEXE]PCSI$MAIN.EXE
                         [SYSLIB]PCSI$SHR.EXE


INSTALLATION NOTES:

No reboot is necessary after successful installation of the kit.
However, users will need to log out and log back in in order to use
the new PCSI features.

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 VMS731_PCSI /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

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

                /PROD=DEC/BASE=AXPVMS/VER=1.0


           -  De-assign the logicals assigned

          For example, a sample command file to install the
          VMS731_PCSI-V0100 kit would be:

          $
          $ DEFINE/SYS NO_ASK$BACKUP TRUE
          $!
          $ PROD INSTALL VMS731_PCSI/PROD=DEC/BASE=AXPVMS/VER=1.0
          $!
          $ DEASSIGN/SYS NO_ASK$BACKUP
          $!
          $ exit
