7.2. Forcing a task
If the attempt to CANCEL a problem task (which can sometime require several CANCEL attempts), has been unsuccessful, then the next step will be to FORCE the task. FORCE is not a substitute for CANCEL. Unless you issue CANCEL first for a cancellable job, the system issues error message IEE838I. The steps to use in the process are:
1. | Issue the CANCEL nnn command, making several attempts if necessary.
|
2. | Use the DUMP command if you want a dump produced. Respond to the prompt for parameters with the jobname or ASID of the “stuck” job, as well as ASID(1)=MASTER.
|
3. | Issue the FORCE nnn,ARM command for non-cancellable procedures.
|
4. | Issue the FORCE nnn command only when the previous steps fail.
|
Important
Never use the FORCE
