For VSAM Files

Before you can use a defined VSAM dataview in a CA Ideal application, the dataview must be cataloged. If a dataview is edited after it was cataloged, you must recatalog the dataview and recompile any programs that use the dataview as a resource.

The CATALOG command for VSAM dataviews lets you specify whether you want to validate the following dataview attributes against the actual characteristics of the VSAM file:

• File organization (ESDS, KSDS, or RRDS)
• Maximum record length (determined by totaling the lengths of the fields defined in the Field Definition fill‑in)
• Displacement and length of each primary and alternate key defined in the Dataview Key Definition fill‑in

To validate the dataview attributes against the VSAM file, the base cluster and any paths in the upgrade set must be available in the current environment. If these cluster components exist in the current environment, validate the dataview attributes when you catalog the dataview definition. However, if these components do not exist in the current environment, catalog the dataview definition without validating the dataview attributes (the dataview is validated when it is accessed).
