      This Customer Software Release Notice (CSRN) provides important
      information for using Release 1.54.00 of the VS XDMS Cluster Server and
      is intended for all users.

      This CSRN is organized as follows:

      Chapter 1 describes enhancements to the release.

      Chapter 2 details hardware and software requirements.

      Chapter 3 lists problems corrected since the last general release.

      Chapter 4 describes restrictions and special considerations.

      Chapter 5 lists the files included in this package.

      Chapter 6 provides installation instructions.

CHAPTER 2
HARDWARE AND SOFTWARE REQUIREMENTS

2.1   HARDWARE REQUIREMENTS

      A 16-MB Virtual Address Capable processor linked with with another
      similar processor utilizing RSF controllers.


2.2   SOFTWARE REQUIREMENTS


      VS Operating System 7.54.00 or later

      XDMS version 1.54.00 or later

CHAPTER 4
RESTRICTIONS AND SPECIAL CONSIDERATIONS

      The implementation of XDMS Cluster Server is intended to provide for
      accessability in a clustered environment.  In that a second level of
      file processing is being added it should be understood that performance
      measurements for IO processed accross the cluster will have somewhat
      greater CPU costs.  Application performance levels have been found to be
      at acceptable levels.  Careful tuning in a multi-system environment is
      much more important.

      This release no longer supports the COBOL verb 'Hold Extention Rights'.

      Rollforward recovery cannot be performed across the cluster.

      The XDMSSERV does not update file IO counts until a file close operation
      is issued, this will affect the accuracy of SAM data collection and
      analysis.

CHAPTER 6
INSTALLATION


6.1   PRELIMINARY STEPS FOR UPGRADES

      1. Inhibit logons and ensure that all users are logged off the system.

      2. Logon to the system as a system administrator.



6.2   SOFTWARE INSTALLATION USING VS BACKUP (All CP Types)

      Refer to the "VS Media, Transfer, and Device Utilities Reference" for
      instructions on using the BACKUP and DISKINIT utilities.

6.2.1 Running BACKUP

      1. Mount the volume containing the Release 1.54.00 XDMS Cluster Server.

      3. Using BACKUP, restore the release to the system volume disk, using
         the following specifications:

         INPUT screen:
                 VOLUME = (volume name of distribution media)
                 DEVICE = TAPE         FUNCTION = RESTORE
                            ERRDISP  = YES
                            FILESEQ  =
                            MOREFILE = NO
                            SELECT   = NO

         OUTPUT screen:
                 VOLUME = (name of new system volume)
                 DEVICE = DISK
                 CLEAR  = NO







         OPTIONS screen:
                 DUPFILES = SCRATCH

         LOGFILES screen:
                Press ENTER to obtain a log file.


             EOJ screen:
                Press PF16 or ENTER to terminate BACKUP.

      4. Dismount the release media from the tape drive.


6.3   FINAL STEPS

      1. If you are not IPLed, do so at this point.  Inhibit logons.  Specify
         the normal configuration file.
