Simple question which I can't find the answer. When is a dataset catalogued and available to other jobs - at the end of the step or at the end of the job? I'm planning to catalog a tape file in each step of a job with 8+ steps. I like to tell the DBA that a file is available for him to load after each step. Can I do that? Or do I have to wait until the job completes to have the files available?

btnwood,

If you are creating a new dataset and cataloging it , then it is available only AT THE END OF THE JOB. You need to wait for the completion of jobs.

Hope this helps...

Cheers

Kolusu,
I had a similar requirement years ago, wherein I wanted jobs to be triggerred as and when a Step is complete, and the file from that step was used to trigger an update job. I don't recollect now but its something that can be tweaked on CA7 to release the file for further processing as soon as the step is complete. What do you think ?

SureshKumar,

I am not aware of a feature in CA-7 which lets you release the dataset after completion of the job. I will check the manuals

Thanks

Kolusu

Coding FREE on the DD card will release the dataset when the last step that uses it ends.

Hi Kolusu

As u said, a dataset is cataloged at the end of the job, but when u try to access the same dataset in the next step of the same job u wont be giving the VOLUME and UNIT parameters as required by uncataloged data sets.

Can u please correct me if I am wrong

Regards

Hi K.V.,

I think you're right; the dataset is cataloged at step end and a non-cataloged ds "exists" as a completed entiy at step end. But they are still "reserved" to the creating job (as are DIDP=OLD ds) until job end or, as bithead noted, until a "free" is issued for it.

Existence and availability are not the same thing.
