OpenVMS VMS721H1_CLIUTL-V0100 Alpha V7.2-1H1 CLIUTL ECO Summary

TITLE: OpenVMS VMS721H1_CLIUTL-V0100 Alpha V7.2-1H1 CLIUTL ECO Summary

New Kit Date     :  07-FEB-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 CLIUTL on OpenVMS Alpha V7.2-1H1.  This kit addresses
the following problems:

Problems Addressed In VMS721H1_CLIUTL-V0100:

  o   Issuing two different SET DEVICE commands can crash  a  system
      with  a  SSRVEXCEPT  bug  check.  An excerpt of the crash dump
      follows:

          Crashdump Summary Information:
          ------------------------------
          Bugcheck Type:     SSRVEXCEPT, Unexpected system service exception
          Current Process:   STARTUP
          Current Image:     $1$DKB406:[SYS0.SYSCOMMON.][SYSEXE]SET.EXE
          Failing PC:        FFFFFFFF.8018C338    NSA$SIZE_NSAB_C+000D8
          Failing PS:        00000000.00000203
          Module:            SECURITY    (Link Date/Time: 29-MAR-2000 00:55:08.31)
          Offset:            0000E338


          Images Affected:  [SYSEXE]SET.EXE

  o   A DCL (Digital command language) $ SHOW CLUSTER  command  will
      hang  on  startup  on cluster-nodes with many SCS ports, e.g.,
      CIPCA,   CIXCD,   MC:...    or   Pxx0:    devices,   if    the
      virtual-circuit  (PB$ path-block) count exceeds four times the
      SCS-node count.  An "SCS-node" is defined as any  SCS-speaking
      node,  such as HSJxx/HSCxx Storage Controllers, RFxx DSSI disk
      controllers, or VMS nodes, etc.

          Images Affected:  [SYSEXE]SHWCLSTR.EXE

  o   If a user attempts to use the SET FILE command to  set  global
      buffers  or  statistics  on a file that is already accessed by
      another user, an error message displays:

             %SET-E-READERR, error reading 
             -SYSTEM-W-ACCONFLICT, file access conflict


      This is an issue with 24x7 sites in which users  may  want  to
      tune or analyze the performance of live files.

          Images Affected:  [SYSEXE]SET.EXE

Problems Related To RMS Addressed In VMS721H1_CLIUTL-V0100:

  o   Fix for interaction between SET RMS_DEFAULT /CONTENTION_POLICY
      and /QUERY_LOCK settings.

      The process and system defaults for these two  qualifiers  are
      correct when the system is initially booted and will remain so
      if  neither  setting  is  changed.    Any   setting   of   the
      /CONTENTION_POLICY  works  correctly for the CONTENTION_POLICY
      value; however, it also  changes  the  QUERY_LOCK  setting  --
      generally to disable.  Since the QUERY_LOCK disable setting is
      ignored by RMS unless both the RAB$V_NLK and RAB$V_RRL  record
      unlocking  options are set within the application, this is not
      expected to have a negative impact.  However, any users trying
      to  change  or  reset the /QUERY_LOCK setting itself will find
      they are not able to.

      In order to  change  either  or  both  of  the  settings,  the
      workaround  until  this kit is applied is to always enter both
      /CONTENTION_POLICY and /QUERY_LOCK in the same SET RMS_DEFAULT
      command.

      For  example,  if  the  user  wishes  to   change   just   the
      CONTENTION_POLICY  system  value  to  "always"  and  leave the
      QUERY_LOCK default as "enable," the following  command  should
      be entered:

      $ SET RMS_DEFAULT/SYSTEM/CONTENTION=ALWAYS/QUERY=ENABLE
      Or if the user wishes to change QUERY_LOCK  to  "disable"  and
      leave the default setting for CONTENTION_POLICY:

      $ SET RMS_DEFAULT/SYSTEM/CONTENTION=NEVER/QUERY=DISABLE

      To restore the settings to  the  default  system  values,  the
      following command should be entered:

      $ SET RMS_DEFAULT/SYSTEM/CONTENTION=NEVER/QUERY=ENABLE

          Images Affected:  [SYSEXE]SET.EXE

      This fix is included in the next release after  OpenVMS  Alpha
      V7.2-1H1.


  o   New qualifier /SHARE added to SET FILE.

      The /SHARE qualifier allows you to enable  or  disable  global
      buffers  or  statistics  on a file currently being accessed "0" CELLSPACING="0" CELLPADDING="0">
