Immediate shutdown of CICS Transaction Gateway forces the
abnormal termination of transactions that are already in progress.
This method of shutdown is not recommended, for the following reasons:
- There is no guarantee that any work will complete.
- There is no guarantee that any tidy-up is performed.
During an immediate shutdown, the following guidelines apply:
- Transactions already in progress are terminated abnormally.
- All in progress one-phase-commit LUWs are backed out (rolled back)
and not recovered.
- For XA transactions:
- All pre-prepare work is rolled back.
- All post-prepare work is left in RRS to be recovered either upon
restart, or by another CICS® Transaction Gateway in the
same Gateway group.
Stop the Gateway daemon,
as described in Stopping a Gateway daemon.
