APAR status

• Closed as program error.

Error description

• DB2 termination with RC00E50702 during the recovery of ABEND0C4
  from DSN3RRSM followed by ABEND0C4 from DSNVEUS2 when RRSAF
  application was MVS cancelled after application of UK81228 or
  UK81229 for APAR PM68365.
  The following symptom can exist:
  ABEND0C4 RSN00000004,M=(N),C=910.ASMC
  -DSNVICEU,M=DSNVEUS2,LOC=DSNVGEPL.DSNVEUS2+0BAA"
  

Local fix

• Restore UK81228 or UK81229
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All DB2 for z/OS users of RRSAF connected    *
  *                 applications who have applied PE PTFs        *
  *                 UK81228 or UK81229.                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: An ABEND0C4 in module DSN3RRSM may      *
  *                      occur when an application connected to  *
  *                      DB2 via RRSAF is cancelled or timed     *
  *                      out.  This ABEND0C4 is followed by an   *
  *                      ABEND0C4 in DSNVEUS2 and DB2 may        *
  *                      terminate with RC00E50702.              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  If an application connected to DB2 with RRSAF is cancelled or
  initiates time out abends while a z/OS RRS UR is still active,
  MVS context services and RRS will drive a DB2 RRSAF backout
  exit.  An ABEND0C4 may occur in module DSN3RRSM.  A subsequent
  ABEND0C4 may occur in DSNVEUS2 and DB2 may terminate with
  RC00E50702.  This problem occurs when PTFs UK81228 or UK81229
  for APAR PM70056 are installed.
  If DB2 commit or abort processing was interrupted by the
  application cancel or time out abend of the thread, DB2 requires
  an explicit commit or abort of the DB2 UR to release resources
  associated with the UR.  With this APAR fix, there will be an
  opportunity for the application to abort the UR, or for MVS
  context end processing to abort the UR, or for DB2 deferred end
  of task processing to abort the UR.
  Additional symptoms:
  ATR306I msgATR306I
  

Problem conclusion

• Module DSN3RRSM has been updated to avoid this ABEND0C4 in
  DSN3RRSM.
