Purging CICS tasks

To purge a task that issued the CICS enqueue that is locking a resource:

Enter the P or F prefix command against the listed enqueue on the CICS Enqueue Selection List panel.
FM/CICS issues a SET TASK PURGE or SET TASK FORCEPURGE CICS command respectively against the task.

Note:

You cannot issue a P line command (SET TASK PURGE) for tasks defined as not purgeable (Prge on the CICS Enqueue Selection List panel shows as NO).
You can issue an F line command (SET TASK FORCEPURGE) against a task defined as not purgeable. Before issuing the first PURGE or FORCEPURGE, FM/CICS displays a warning panel asking you to confirm the purge.
If the purge was successfully issued against one or more tasks, FM/CICS changes the entry on the CICS Enqueue Selection List panel to *** PURGE ISSUED ***. This does not indicate that the task was successfully purged, but only that the purge command was successfully issued.

If the purge command failed, FM/CICS changes the entry on the CICS Enqueue Selection List to *** PURGE ERROR *** and displays the condition and RESP2 values returned by CICS at the bottom of the panel.
Issuing PURGE or FORCEPURGE against a task terminates the task. Therefore, you should issue a REFRESH command after purging one or more tasks to produce a current list of all active CICS enqueues.
