Required Parameters

When attributes of a catalog are altered, entryname must include either the data or index components. Giving the catalog name alters attributes defined at the cluster level only. The catalog name is also the data component name.

The restricted prefix SYS1.VVDS.V or its generic form SYS1.VVDS.* or SYS1.*.V is not allowed as an entryname for the ALTER command.

If you are renaming a member of a non-VSAM partitioned data set, the entryname must given as: pdsname(membername).

See the NEWNAME parameter for information on renaming SMS-managed data sets.

Identify a generation data set (GDS) with its generation data group (GDG) name followed by the generation and version numbers of the data set (GDGname.GxxxxVyy).
