Unlocking the Checkpoint

You can unlock the checkpoint if the started task abnormally ends on a system, or if a system running CA Deliver fails while CA Deliver has the checkpoint locked.

Note: As long as the checkpoint is locked on a system, no other system can get it.

Never unlock a started task that shows the following message:

RMOSTC01 CA DELIVER IS INITIALIZED

Important! Under no circumstances should you unlock the checkpoint when the started task that holds the lock is still executing.

For example, if a started task hangs with the checkpoint locked, the started task could 'break free' and resume processing.

If the checkpoint is reset under these conditions and the started task resumes processing, the checkpoint could be damaged. If the checkpoint needs to be reset, cancel the started task that is hung and then issue the UNLOCK command on another CA Deliver started task executing on a different system image.

To unlock the checkpoint, issue the following command:

F RMOSTC,UNLOCK

where RMOSTC represents your STC name
