Uncatalog a dataset tape with CA1

[samb01]

Hello,

is it possible to spécify to CA-1 to uncatalog a tape dataset when the tape is scratch.

[Robert Sample]

If the tape is scratch, then nothing on it is cataloged -- so why on earth would you think you need to UNCATALOG something that doesn't exist, much less use CA1 for that?

I think CA1 uncatalogs datasets that are cataloged on a tape volume when it moves a tape volume to the scratch pool. It has been more than 20 years since I did anything serious with CA1, so I don't remember all the options, and this may be a CA1 option. Check the CA1 manuals, or contact CA support for assistance.

If you find a dataset is cataloged to a tape in the scratch pool, you can use DELETE dataset-name NOSCRATCH in IDCAMS to uncatalog the dataset.

Hello Robert Sample,

and thank's for youy answer.

I kwnow the tape is scrath in CA 1. But the entrie in catalog is still existing, even if the tape is scratch. I just want to erase this entri Catalog.

I just want to erase this entri Catalog.

Then do what Steve Myers suggested.

In other words, what you are saying is that there is a discrepancy between the system catalog and the CA-1 database. This is a very different problem from what you originally stated, and if you read up in the CA-1 documentation you can find out how to resolve it yourself. If you don't have the CA-1 documentation, and your site is licensed for CA-1, you can get the documentation yourself from the CA support web site.

You might have a very serious flaw in your parameters or processing. A tape should not go scratch if it has a live dataset or dataset that is still cataloged on it. All of your sirens and alarm bells should be ringing and you need to examine exactly how this happened. You should also bring this to the attention of your co workers.

A tape can go scratch if its expiration date has been reached, unless one or more datasets are flagged as "catalog" expiration, which means the tape can be "scratched" if the dataset is uncataloged. "Catalog" expiration is intended for GDG datasets, but it works the same for non-GDG datasets.
