Getting a deferred restart

To ensure that automatic restart activity is canceled, but that the checkpoints are still available for a deferred restart, specify RD=NR in the EXEC or JOB statement when the program is first executed.

Read syntax diagramSkip visual syntax diagram>>-RESTART--=--(--stepname--+----------+--)--------------------><
                            +-,--------+
                            '-check-id-'
 

If you subsequently require a deferred restart, you must submit the program as a new job, with the RESTART parameter in the JOB statement. Use the RESTART parameter to specify the job step at which the restart is to be made and, if you want to restart at a checkpoint, the name of the checkpoint record.

For a restart from a checkpoint, you must also provide a DD statement that defines the data set containing the checkpoint record. The DD statement must be named SYSCHK. The DD statement must occur immediately before the EXEC statement for the job step.
