CSICATNM is used for catalog selection. The following paragraphs describe how CSI performs catalog selection.

CSI will use the catalog name supplied in CSICATNM to search for entries if CSICATNM is not blanks. If CSICATNM is blanks, Catalog Management will attempt to use the high-level qualifier of CSIFILTK to locate an alias that matches. If an alias is found, the user catalog for that alias will be searched; then, the master catalog will be searched. The master catalog will not be searched if CSIS1CAT is set to Y. If no alias is found, only the master catalog will be searched.

Caution should be exercised in using high-level qualifiers that contain generic filters because multiple catalogs can be searched. A high-level of "**" will cause a search of every user catalog in the system.

CSIS1CAT can be used to limit the search to one catalog only. This is useful if the filter key could cause catalog management to select more than one catalog for searching. Also if not set, the master catalog will be searched in addition to one selected user catalog. In cases where the catalog name is supplied as input and a resume is done, CSIS1CAT will cause only that catalog whose name is supplied as input to be searched. Otherwise, on resume, catalog management cannot tell whether this is a search across many catalogs and the resume caused the CSICATNM to be set or if the name was supplied by the caller.

If a tape volume catalog library entry type or a tape volume catalog volume entry type is specified in CSIDTYPS, a tape volume catalog will be searched. Tape volume catalog library entry types and tape volume catalog volume entry types should not be mixed with catalog entry types.
