I know if I issue an MQCMIT that both my outstanding DB2 updates/inserts/deletes will be "hardened" as well as my uncommitted MQ messages will be committed.
The question is if I code an "EXEC SQL COMMIT WORK END-EXEC" statement will this have the same effect? Or will just my DB2 stuff be committed and not my MQ?
Thanks in advance,
Larry

Hi,
May be you should look at the following :
Resource Recovery Services (RRS)
This may affect Task 18 in Chapter 2, “Customizing your queue managers”,
on page 7.
You can migrate your existing batch/TSO WebSphere MQ applications to
exploit RRS coordination with little or no application program change. If
you link-edit your WebSphere MQ application with the CSQBRRSI adapter,
MQCMIT and MQBACK synchronize your unit of work across
WebSphere MQ and all other RRS-enabled resource managers. If you
link-edit your WebSphere MQ application with the CSQBRSTB adapter,
you must change MQCMIT and MQBACK to SRRCMIT and SRRBACK.
Version 5.3.1 continues to support the non-RRS managed batch adapter in
addition to supporting the RRS managed adapter. Thus different versions
of WebSphere MQ queue managers can coexist on the same z/OS image.
Regards,
JM
