  *                      command UPDATE DB NAME(xxxxxxxx)        *

  * 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.
