Hi Guys,
I ve read in a link abt Catalog - Volume ownership, It says

Catalog - Volume Ownership
When a given direct access storage volume contains a VSAM catalog (either the master catalog or a user catalog), the catalog must be the first VSAM object stored on that volume. A VSAM catalog owns the volume on which it resides. All the VSAM objects that are defined on a volume containing a VSAM catalog must be cataloged in the catalog residing on that volume. A catalog can also own other volumes; however, those volumes cannot also contain other VSAM catalogs. When the first VSAM object on a volume that does not contain a VSAM catalog is defined, that volume becomes the property of the catalog that contains its catalog entry.

I want some clarification on this topic.. u can ve look at this link also http://www.jaymoseley.com/hercules/vstutor/vstutor.htm

Hello,

I want some clarification on this topic..

About the quoted info? It is not clear what you want additional clarification about.

Suggest you add this link to your collection for technical material:

This is talking about VSAM catalogs, which were replaced by ICF catalogs around 20 years ago. Virtually none of that stuff applies anymore.

Read HERE for some more up to date catalog information.

If you are running an ancient OS under hercules, you will be using and learning things that no longer apply under z/OS. Admittedly a lot of the commands may still apply but not all of them. Certainly VSAM data space allocation is no longer applicable.
