IT05827: IBM MQ V8 COA REPORT MESSAGE DESTINED TO A REMOTE QUEUE ENDS UP IN DLQ WITH MQRC_MDE_ERROR.

Fix Pack 8.0.0.2 for WebSphere MQ V8.0

APAR status

• Closed as program error.

Error description

• When sending messages having RFH2 and the Confirm on Arrival
  (COA) destination specified to a remote queue, the COA message
  ends up on the DLQ. The sender client application is on a remote
  machine and the RFH2 message is sent to a remote queue manager
  which in turn sends the COA message to a remote queue on another
  remote queue manager. The COA message shows up on the Dead
  Letter Queue of the remote queue manager with MQRC_MDE_ERROR.
  

Local fix

• COA messages destined for a local queue works.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of MQ V8 who use the Confirm On Arrival report message
  feature.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When a message containing an RFH2 is specified with COA whose
  destination is set to a remote queue, the COA message is
  incorrectly built by the queue manager. This causes the COA
  message to be delivered to the Dead Letter Queue with
  MQRC_MDE_ERROR.
  The sender application sends the RFH2 message to a remote queue
  and this message has its COA destination set to another remote
  queue. The COA is then sent to the remote queue and while doing
  this, the queue manager incorrectly builds the COA message with
  the wrong format and thus causes the COA message to end up in
  the remote queue manager's Dead Letter Queue.
  The problem is not seen if the destination of the COA message is
  set to a local queue.
  

Problem conclusion

• The queue manager code is modified so that the COA message is
  built correctly, meaning that the message can be delivered to
  the respective remote queue successfully.
