Syntax to start the job from particular step in JCL
A. Restart=Stepname
B. Restart=Stepname.G
C. Restart=Procname.Stepname
D. All the Above
Answer
The correct syntax to start a job from a particular step in JCL is:
D. All the Above
Explanation
This means you can use any of the following formats with the RESTART parameter to indicate the step where the job should restart:
1. RESTART=stepname
This restarts the job from the specified step name within the JCL.
2. RESTART=stepname.G
Adding “.G” after the step name restarts the job from the step following the specified step name.
3. RESTART=procstepname.stepname
For jobs that execute procedures, this format allows you to specify both the procedure step name and the step name within that procedure to restart from.
The RESTART parameter provides flexibility in choosing the exact point to restart a failed or interrupted job, saving time and resources by avoiding re-running the entire job from the beginning. By specifying the appropriate step name, you can pick up execution from that step onwards.
