OA21981: MPMU ENVIRONMENT , USP STORAGE LEAK , INITUSP , abend878 abend80A

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In a MPMU address space, a process dubbing and
  undubbing will get a USP created for it each time through
  DUB.  The previous USP is not freed and the storage
  is lost.
  In the path for a MPMU (multiproc/multiuser) address space,
  BPXPRIN1 does not check the ACEEIUSP bit to see if there is
  already a USP (user security package) connected to this ACEE.
  This causes a storage leak in ELSQA, leading to multiple
  abend80A's and abend878's.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of Tivoli NetView for z/OS who     *
  *                 make use of UNIX System Services, including  *
  *                 System Automation/390 (SA/390).              *
  ****************************************************************
  * PROBLEM DESCRIPTION: A new USS dub setting is needed for     *
  *                      NetView to allow the fix for USS APAR   *
  *                      OA20171 to be effective.                *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The fix provided by USS APAR OA20171 requires that the job step
  task of the address space specifies a new option, DUBUNIQUEACEE,
  on the Set Dub Defaults (BPX1SDD) invocation. Doing so will
  allow the problem described by OA20171 to be resolved.
  

Problem conclusion

• Module DSIDUBIT is being changed to attempt to invoke the
  BPX1SDD callable service with varying combinations of options,
  starting with all the ones required by NetView. If the request
  fails, another attempt will be made using less
  recently-available options. For each attempt that fails,
  msgBNH284E will be issued stating that the specific function is
  not available. When an invocation of BPX1SDD works, msgCNM910I
  will be issued stating which options were successful. The
  options that are attempted follow, in the order they will be
  attempted:
    PROCESSDEFER+JOBPERM+NOJSTUNDUB+UNIQUEACEE
    PROCESSDEFER+JOBPERM+NOJSTUNDUB
    PROCESSDEFER
    PROCESS
  Also, because messages BNH284E and CNM910I are being used in
  this new way, the descriptions of these messages are being
  changed. To do so, the Tivoli NetView for z/OS V5R2 Messages and
  Codes Volume 1 (AAU-DSI) (SC31-6965-00) and the Tivoli NetView
  for z/OS V5R3 Messages and Codes Volume 1 (AAU-DSI)
  (SC31-6965-01) should be changed as follows:
   The description of message BNH284E should be changed as
   follows:
    The description of the 'function' message variable should be
    changed to read as follows:
     function The function that your current installation does not
              support
    The Operator Response should be changed to read as follows:
     Operator Response: If appropriate, verify that the command
     was entered correctly, then correct and reenter the command
     request.
  
     If the command is 'BPX1SDD', then the UNIX System Services
     Set Dub Defaults request issued by the NetView program during
     its initialization has failed when attempting to specify the
     options indicated by 'function'.
  
     If support for the function should be available, contact your
     system programmer and indicate that the specified function
     has not been installed.
   The description of message CNM910I should be changed as
   follows:
    New Operator Response and System Programmer Response sections
    should be added to read as follows:
     Operator Response: If 'command' begins with 'BPX1SDD', then
     the UNIX System Services Set Dub Defaults request has
     succeeded with the indicated options. One or more instances
     of message BNH284E may have been issued. If no previous
     BNH284E had been issued, all the latest UNIX System Services
     dub defaults functions are installed.
  
     System Programmer Response: None.
  The online help for messages BNH284E and CNM910I are being
  changed as described above.
