PH63733: WHEN BATCH JOB ISSUE SQL, AN ABEND0C4 OCCURS ON CREATE THREAD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An abend0c4 can occur on create thread after application issue
  SQL. The db2 control block structure is not being cleaned up
  correctly for RRS batch job.
  The abend0C4 was result of a reuse of an ASCE from a prior job
  that used RRSAF. All of the resources/storage from the prior job
  were released by MVS at jobstep end.

  This APAR is resolved as a serviceability APAR that is adding
  diagnostic trace footprints to Db2 EOT (End of Task)
  processing.
  The ABEND0C4 in DSNVCRTH occurred because the Db2 ASCE was not
  cleaned up during EOT processing for a previous batch job,
  and the next batch job that executes in the JES initiator
  tried to connect to Db2.
  This problem may occur with some RRSAF multi-threaded batch
  jobs that do not explicitly call RRSAF Terminate Thread and
  Terminate Identify.
  

Problem conclusion

• Db2 will be updated to add diagnostic footprints to EOT
  processing.
