PI20227: DFHMQ0704 IS SENT AS AN ERROR SITUATION, EVEN IT IS NOT.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The message DFHMQ0704 is unclear, and it should provide
  more information when the CICS-MQ Bridge monitor receives a
  ROLLEDBACK response to a SYNCPOINT request.
  .
  The CICS/WMQ DPL Bridge is used in a CICS region where
  the DPL request is routed via the DTR exit EYU9XLOP.
  Task is routed in the first AOR, but it is rejected for routing
  to the first AOR. It causes the TCABRPSR "backout required" bit
  to be set on.  Later, when DFHMQBP2 makes its SYNCPOINT
  request, because TCABRPSR is set, the backout logic is driven
  and the ROLLEDBACK condition is returned along with message
  DFHMQ0704.

  The CICS-WebSphere MQ Bridge issues a SYNCPOINT command, however
  a remote system involved in the current unit of work is unable
  to commit. As a result the SYNCPOINT command is driven into
  rollback and a DFHMQ0704 message is issued. DFHMQ0704 is a
  generic message, populated with values that indicate that a
  SYNCPOINT command received a ROLLEDBACK response, but no further
  explanation is given.

Problem conclusion

• DFHMQBP2 has been modified such that if it receives a ROLLEDBACK
  response to its SYNCPOINT call, it issues a DFHMQ0793 message
  rather than a DFHMQ0704.
  
  The CICS Transaction Server Version 5 Release 2, CICS Messages
  and Codes Vol 1 manual (GC34-7283-00) will be updated as
  follows. In Chapter 4. DFH messages - DFH01 to DFHM, a new
  message will be added immediately after the description of
  message DFHMQ0792I. This new message description will read as
  below.
  
  DFHMQ0793 E date time applid tranid trannum A SYNCPOINT command
  was driven into rollback because a remote system was unable to
  commit.  Any changes made to recoverable resources in the
  current unit of work are backed out.
  
  Explanation: The CICS-WebSphere MQ Bridge issued a SYNCPOINT
  command, however a remote system was unable to commit.  As a
  result the command was driven into rollback.
  
  System action: Processing continues.
  
  User response: Check for associated messages to determine if
  the WebSphere MQ message was reprocessed or moved to another
  queue.  Previous messages may explain why the remote system
  was unable to commit.
