PK88958: ABENDS0C1 DFSRBLB0 ATTEMPTING TO BUILD RIS VIA CALL TO DFSDRIS0 SCDDRSI0 ZERO DFSDRIS0 NOT LOADED FOR CTL=DCC CONFIGURATION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• System running with RRS=Y,CTL=DCC, and executing workload
  based on DB2 as database manager, input from WAS ( OTMA
  Protected input messages ) fails with some transactions
  InDoubt ( Phase I complete ). /ERE abends S0C1 on wild
  branch to low core out of DFSRBLB0 attempting to build RIS
  structure for the IMS unit of recovery. This is because
  for DCC, IMS does not at present load the Resovle Indoubt
  processing logic including DFSDRIS0. SCDDRIS0 -> zero
  In the case of RRS=Y, IMS is not guaranteed to be the
  syncpoint manager and so the RIS code is neccessary.

  CTL=DCC, RRS=Y is specified on a system in which DB2 is the
  resource coordinator. OTMA protected input messages are input
  from WAS and IMS  fails after phase 1 complete, leaving
  transactions in doubt. During restart DFSRBLB0 attempts to build
  the RIS structure by calling DFSDRIS0. DFSDRIS0 is not loaded in
  a DCC IMS and the SCDDRIS0=00000000 field reflects this.
  ABEND0C1 trying to branch to low core results.

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  Code was added to the load lists in DFSIIN10 that will load
  DFSDRIS0, DFSDRID0, and DFSDBIE0 in a DCC IMS system.
