Can I cancel a CICS transaction that is executing?
Yes. In CA SYSVIEW, you can automatically cancel a CICS transaction during execution because all transaction metrics are checked dynamically. The threshold definitions are found in the CTHRESH parmlib member, and the CANCEL parameter can be optionally specified on a threshold definition. You may need to override the dynamic decision to cancel a transaction; the parmlib member CTRANCAN allows you to define cancellation exclusion rules based on transaction ID, facility name, or wait reason.
You can also manually cancel a transaction using various line commands from the CTASKS command display.
