Hi,
To fix a issue, in our application, we require an MQ rollback. Following is the scenario:
1)Program A puts message on MQ ABC.
2)MQ ABC, has trigger Y, so it invokes a transaction XX which further invokes a program B.
3)Program B is invoked in MQ region which further invokes a program C in ZZ region i.e. in AOR
4)Now, for a condition i want to rollback the changes and put the same message on MQ, that program C recieved via B, and B through MQ so that when Rollback is issued message on MQ ABC is there.
Way I am trying:
I am issuing EXEC CICS ROLLBACK END-EXEC.
This definitely rollback the DB2 changes and CICS changes, but the message from MQ ABC was consumed.
What i dont want to try:
Definitely, we can write the same message back on MQ from prog C, but that's the last option we have kept with us, coz that will require lot of access and permissions.
Could you please help me.
I am sorry for such a long message but thought of describing the situation completely. Please let me know in case any further information is required.
Thanks.

| Was the MQGMO_SYNCPOINT option included in your Get Message Options? |

I can confirm the same, once I am logged in. That will take another 8 hours. Apologies.
between, what are the possibilities if we go with IF & else clause here?
Thanks. |

| MQGMO_SYNCPOINT is used while issuing GET. What now? |

You can only rollback on the queue manager associated with that region

If program B consumed the message - it's gone from the queue.
How does B pass the message to C? |
