Use the CATALOGFILE parameter to change the file name for the catalog with the CATALOGFILENAME command-line option. Disable CATALOGFILE by specifying NOCATALOGFILE or NOCTLGFILE. The effect is the same as NOCATALOG. Catalog information is not created during ARCHIVE, and is not used during RESTORE or COPY.
When using the CATALOG option of ANALYZE along with the CATALOGFILE / CATALOGFILENAME parameters, ANALYZE writes to both the CATALOG table on the database and the specified client-side file.
In mainframe platforms (for example, z/OS), limit file names to eight characters.
