Hi,

Please clarify the following doubt.

I read that GDG's will be updated only after execution of the job. My question is what is exactly "Update" in this case? Please elaborate the term Update.

Thanks,
Kiran.

where did you read that?.. Is that question in regard to relative generation numbers?

I think he is referring to the GDG relative number itself.. If you create a new generation in step 1 of a job (+0), all subsequent steps in the same job that reference this new generation must code (0) as well... It doesn't become +1 until after the job completes (catalog)

shagnwrx,
you've got it backwards:
If you create a new generation in step 1 of a job (+1), all subsequent steps in the same job that reference this new generation must code (+1) as well... It doesn't become (0) until after the job completes.

Please note that the job does not have to terminate correctly as long as the step creating the GDG dataset completes OK - and even then what happens depends on the DISP used.

what if job abends in the second step ? when we restart the step2..do we need to refer it as 0? I think it should be.
