You can use the CICS(R) CEMT transaction to purge user tasks that are using the CICS adapter. Tasks that are waiting on the adapter respond only to CEMT SET TASK FORCEPURGE commands--CEMT SET TASK PURGE commands are ignored. The way the adapter handles a FORCEPURGE command depends on the kind of wait state that the task is in:
The adapter waits for the request to complete, and then checks whether it is suitable to end the task:
A task is in a critical state is when, for example, it is in the process of completing phase 2 of a two-phase commit sequence.
For information about CEMT commands, see the CICS-Supplied Transactions manual.
