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 3 Release 2, CICS Messages
    and Codes manual (GC34-6827-04) will be updated as follows. In
    Chapter 1. DFH messages, 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.
