PI21447: rc61444 and Gateway object closed after Java client application sends XA_ROLLBACK.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A client application flowed an XA_ROLLBACK to terminate an
  in-flight request. The transaction was terminated with the
  expected abendAITJ and the following message was written by
  CICS:
  DFHIS0998  A transaction processing a request using IP
  Interconnectivity has abended with code AITJ.
  The above was expected, but the Java client application received
  return code 61444 and the Gateway object in the J2E server was
  closed.
  A subsequent transaction might also receive an unexpected
  ECI_ERR_SYSTEM_ERROR return code.

  ****************************************************************
  When the Gateway daemon received an XA_ROLLBACK request for an
  in-flight transaction, it sent an XA_ROLLBACK to the CICS
  server. At this point CICS TG was in receive state and the
  CICS server was in send state, so the CICS server was not
  expecting to receive the XA_ROLLBACK. The transaction was
  correctly abended in the CICS server, but CICS TG incorrectly
  sent an rc61444 to the client application causing the Gateway
  object to be closed. CICS TG should have sent a PURGE instead
  of the XA_ROLLBACK.
  After cleaning-up from this error, a worker thread is left
  waiting for a response to the XA_ROLLBACK. It might incorrectly
  interpret a response for another request as the XA_ROLLBACK
  response and return ECI_ERR_SYSTEM_ERROR to the client
  application.
  

Problem conclusion

• CICS TG has been changed so that a PURGE rather than an
  XA_ROLLBACK will be sent to CICS over an IPIC connection
  when CICS TG is in receive state.
