Hi Vansee,
Ofcourse u have a lakh of job step. Once any of the step abended , then the sub sequent steps aren't run. So you have to restart the step with RD parameter.

Hello vamseepotti,

Folowing is the excerpt from the JCL User's Guide

Restarting after Abnormal Termination

If a job terminates abnormally, the checkpoint/restart facilities allow you to restart the job, as follows:

1) Automatic step restart, that is, restart by the system from the beginning of a job step.
2) Automatic checkpoint restart, that is, restart by the system from a checkpoint within a job step.
3) Deferred step restart, that is, restart at a later time from the beginning of a job step.
4) Deferred checkpoint restart, that is, restart at a later time from a checkpoint within a job step.

Restarts are controlled by:
1) RD parameters on JOB and EXEC statements. (Restart is not supported for started tasks; do not use the RD parameter on the JOB statement for a started task.)
2) Checkpoints, if written. Each time a CHKPT macro is executed, a checkpoint is written.
3) The job journal, which is only required for an automatic restart. In a JES3 system, the programmer can code a JOURNAL parameter on the JES3 //*MAIN statement to control whether JES3 creates a journal for the job.
4) In deferred restarts, a RESTART parameter on the JOB statement for the restarting job and a SYSCHK DD statement to identify the data set containing the checkpoint written in response to the CHKPT macro. (Restart is not supported for started tasks; do not use the RESTART parameter on the JOB statement for a started task.)

Hope this helps,
