how to restart the step that got abended

I have 25 steps in a JCL job. I'm creating a new GDG(+1) in my first step. I'm referring to the same GDG in the 25th step. While executing the job, it got abended in 24th Step. Can I restart the job from 25th step and if so, what modifications do i need to do?

As your GDG is already created in the first step, restart the job from 25th step by changing the GDG as GDG(0). This will solve your problem.

For this reason relative GDG #s are usually coded as symbolic params (e.g &GEN1). Then you only have to provide the symbolic (gen1=0) rather than o'ride the DD stmt.

Friends,
I had read in one of the Books,GDG's are catalogued only at the end of the successful execution of job..SO if your job has got abended,even though Step 1 has executed successfully,the new version will be deleted ..
So while restarting we have to restart from Step1 ....

Correct me if I am wrong ?

Hi sats,

I think you may have misunderstood what the author meant.

The creator has control over what happens to the GDG entry at EOJ (actually EOStep) via the DISP param. If you create a GDG in Step1, whether it's cataloged or deleted depends on your DISP and the step's completion (abend or non-abend).

You're correct in this sense:

Other jobs cannot access the GDG until the job that creates it ends. On the other hand, succeeding steps in the creating job can access it using the same relative GDG# that it was created under. Provided that the creating
DISP is correct.
