Error description
In DFHMQTRU, the first time in processing involves initialising the LOT and it also sets the uowid in the lot (i think for debug purposes) and then later it sets the uowid field in the RPL if fnewuowid is set. The else clause on the above IF is empty. Instead, it could setting fnewUow to drive the existing code lower down and ensure the new uowid gets moved into the QRPL.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS WMQ users * **************************************************************** * PROBLEM DESCRIPTION: DFHRM0129 then DFHMQ0318. UOWs could * * not be resolved between CICS and MQ. * **************************************************************** MgDFHRM0129 Intersystem communication failure and then the DFHMQ0318 message when CICS reconnected to another QMGR. CICS did not know about the UOWID reported in msgDFHMQ0318 and so was unable to resolve the UOW. On the first entry to the TRUE the UOW ID is saved and passed to MQ. When a syncpoint occurs a new UOW ID is created but subsequent entry to the TRUE will still use the initial UOWID.
Problem conclusion
Temporary fix
Comments
DFHMQTRU is changed to check that the UOW is the same on a syncpoint on subsequent entry and if yes will pass the new UOW ID to MQ.
