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. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Message DFHMQ0704 is issued for a * * ROLLEDBACK syncpoint, but the message * * text is not specific enough to reflect * * this. * **************************************************************** * RECOMMENDATION: * **************************************************************** 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. Keywords: msgDFHMQ0704 msgMQ0704 MQ0704 msgDFHMQ0793 msgMQ0793 MQ0793
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.
