Hi,
Can someone clarify my basic doubts.
1. Will MQ commit and rollback work for Remote defintion queue. If no, how to handle it
2. How different will it behave in case of clustered queue.
3. we are having AS400 in our shop and when we try to issue COMMIT command in AS400 it doesn't work for MQ , The queue is defined as Remote definition queue. What does that mean.
Thanks

Remote queue defs simply map onto a local xmit queue.
So rollback and commit work exactly the same as a local queue.
What do you mean by COMMIT command?
If you MQPUT with MQPMO_SYNCPOINT then MQCMIT or MQBACK will work.
If you MQPUT without specifiying SYNCPOINT then MQCMIT and MQBACK have no effect since the default option is NO_SYNCPOINT.
Check all MQRCs and report anything non-zero. |

Yes if the message is put inside a UOW by the application.

It doesn't behave any differently; clustering changes how the target queues are selected not how UOW is handled.

COMMIT isn't a command AFAIK (but I'm not an AS400 person). What do you mean by "it doesn't work for MQ"? Do you mean it works for other things? Are you attempting a co-ordinated 2-phase commit? If so, is the queue manager properly participating?

Here is the problem,
The MQBACK and MQCOMIT is not working in AS400. Only the AS400 COMMIT and ROLLBACK is to be used as per the red books.
But when we try to issue COMMIT with in the UOW and process abends in between it rollbacks the entire UOW inspite of the fact that intermediate COMMIT has been done. |

| Open a PMR with IBM if their products do not appear to work as advertised. |
