A client has a
problem where his MQ application is failing but he says the MQ updates are not
rolling back. I'm sure he's got something wrong in his code but before I berate
him I just want to confirm my understanding and ask if there are any known
issues.
If an application
(WIN2K) gets a message using MQGMO_SYNCPOINT and then issues a MQDISC (but
no preceding MQCMIT) the MQGET is committed. If on the other hand it just ends
normally but does not issue a MQCMIT or MQDISC) the MQGET is rolled
back.
I've tried this
using the API Exerciser in First Steps and it seems to confirm this.
1) Is this correct
?
2) If the Win2K
application runs as a Windows service does it still work the same
?
If so, can anyone
think of any reasons why the MQGET might not be rolled back when the
application ends.
TIA
Steve.
