PM56115: ALLOWUSERKEYCSA(NO) RESULTS IN ABEND B78 RC=5C WHEN USING THE EXTERNAL METHOD OF NOTIFICATION (THE ENF TIMER)

APAR status

• Closed as program error.

Error description

• Abends occur if StatisticsMajorInterval=0 is set. The JOBLOG
  of the execution group is showing the following:
  ABENDB78 RC=5C at
  ImbEventNotification::RegisterToListen(RcRsVal*).
  
  ABENDB78 RC=5C means:
  A program attempted to obtain user key (8-F) storage from a
  CSA subpool, and ALLOWUSERKEYCSA(NO) was specified in a
  DIAGxx PARMLIB member.
  
  There is only one place where Broker invokes the STORAGE
  (OBTAIN) macro for subpool 228 (CSA) and uses key 8. This is
  when Broker attempts to register to listen for event
  notification using the ENF timer. The Broker runs in key 8 and
  accesses all of its storage on the heap using key 8. Since
  z/OS changed the default of the ALLOWUSERKEYCSA parameter to
  NO, accessing storage in CSA using key 8 is no longer possible.
  
  z/OS broker customers who want to use the external method of
  notification (the ENF timer) for statistics and accounting
  archive records, should run with ALLOWUSERKEYCSA(NO), so
  WebSphere Message Broker has been changed to access CSA
  storage using key 7.
