    * PROBLEM DESCRIPTION: ABENDS0C4 occurs in the processing of   *
    *                      command UPDATE DB NAME(xxxxxxxx)        *
    *                      STOP(QUIESCE), where xxxxxxxx is a      *

    *                      database DBR'd.                         *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    After command 'UPDATE DB NAME(xxxxxxxx) STOP(QUIESCE)' is
    entered for a partition of a PHIDAM database with its master
    database DBR'd, an ABEND0C4 occurs in module DFSDBQ00.  The
    DBR'd status of the master is detected with a non-zero return
    code and the DBRC END call needed flag (dbrcendneeded) is also
    set.  Later in the process it checks for either zero return code
    or the flag since the flag is set so it calls routine
    ProcessDBRCList with the stopped master, which does not have
    proper quiesce list entry pointers set up and causes the abend.
    When the STOP(QUIESCE) keyword is specified in the command the
    dbrcendneeded flag should not be set.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    Module DFSDBQ00 has been modified not to set the dbrcendneeded
    flag if the STOP(QUIESCE) keyword is provided in the command
    syntax.  So it will skip the ProcessDBRCList call when the
    master DB is stopped.
