Modifying checkpoint/restart activity

You can cancel automatic restart activity from any checkpoints taken in your program by executing the statement:

CALL PLICANC;

However, if you specified RD=R or RD=RNC in the JOB or EXEC statement, automatic restart can still take place from the beginning of the job step.

Also, any checkpoints already taken are still available for a deferred restart.

You can cancel any automatic restart and the taking of checkpoints, even if they were requested in your program, by specifying RD=NC in the JOB or EXEC statement.
