How ECMF Handles Requeued Jobs When CA MIM Terminates

ECMF maintains checkpoint information for requeued jobs in the CA MIM checkpoint files. By default, ECMF releases requeued jobs if CA MIM terminates and accumulates new checkpoint information when you restart CA MIM. You can change the way ECMF handles requeued jobs and checkpoint information by specifying one of these values on the SETOPTION REQCKPT command:

ASK

Tells ECMF to issue the MIM1049 WTOR, which asks the operator how to handle requeued jobs and checkpoint information.

DISCARD

Tells ECMF to leave the jobs in a held state and discard checkpoint information. Release these jobs manually.

RELEASE

Tells ECMF to release requeued jobs and accumulate new checkpoint information when you restart ECMF.

This is the default.

USE

Tells ECMF to leave the jobs in a held state until you restart ECMF. When ECMF is restarted, it rebuilds the checkpoint information and releases the jobs. If the job needs a data set that is still unavailable, then ECMF reinstates the job to the control of ECMF. If the data set is available, then ECMF releases the job immediately.
