IT26699: AMQ9544 error message is incorrectly reported in a scenario where AMQ9527 should be reported

APAR status

• Closed as program error.

Error description

• Consider a scenario where requester/receiver/cluster receiver
  channel that has asked for a batch of messages, but a local
  target queue is full, lets assume we don't have DLQ's defined at
  either end. As we can't DLQ at the requester end, we reject the
  batch and the sender/server then states it also can't DLQ and
  sends us the ESH with rfpERR_CAN_NOT_STORE. In this scenario
  rrcI_MSGS_PUT_TO_REMOTE_DLQ(AMQ9544) is reported when the
  partner has sent an ESH of rfpERR_CAN_NOT_STORE instead of
  reporting rrcE_MSG_NOT_RECEIVED(AMQ9527).  Reporting
  rrcI_MSGS_PUT_TO_REMOTE_DLQ when the partner has sent an ESH of
  rfpERR_CAN_NOT_STORE is incorrect as it means that the partner
  MCA has encountered one of
  
  rrcE_MQOPEN_FAILED
  rrcE_MQPUT_FAILED
  rrcE_NO_DLQ
  
  None of these could indicate a successful remote DLQ operation.

  PROBLEM DESCRIPTION:
  A programming error resulted in incorrectly reporting AMQ9544
  error message in the scenario where AMQ9527 should be reported.
  

Problem conclusion

• The MQ code has been modified to make an ESH containing
  rfpERR_CAN_NOT_STORE always issue rrcE_MSG_NOT_RECEIVED
  (AMQ9527) instead of reporting
  rrcI_MSGS_PUT_TO_REMOTE_DLQ(AMQ9544) for receivers, requesters
  and cluster receivers.
