In a JCL, I've temporary data sets getting created in between. In Step 05, a &&TEMP data set with DISP=(NEW,PASS) is created and is input to step 09 with (OLD, DELETE). If the JCL abends at step 07 and we try to restart the job from step 07, will the temporary data set created previously be existing or should I need to restart the Job from STEP 05? Please help.

The temporary data set will not be available after the job completes (whether normal completion or ABEND). Your restart needs to include the step that creates the temporary data set.

Thanks. Can we store the contents of temporary data for some analysis?

Yes - make it a permanent data set - it can be deleted at EOJ.

No -- a temporary data set is a data set that goes away at the end of the job -- period. As Nic said, you can change it to a permanent data set which will stay around after the end of the job, but then it is no longer a temporary data set. And a permanent data set will need to meet the site requirements for name, size, and so forth.

Thanks, got it working. I have allocated dataset and used that.

So can we say theat "temporary" dataset is only meaningful when system is creating them and not a user?

No.

Temporary data sets can be VASTLY useful for users as well as the system.

I could not tell it well what I wanted to ask but that is fine. Thanks for the answeres.

NO, but You are mixing up things ...

being temporary is a property of a dataset, as opposed to being permanent full stop

who/what creates them is completely irrelevant to the property

who is the system and who is the user
