3.2 Catalogs
If a “SHOW CATALOG/FULL” does not display a directory for a catalog it means the catalog’s
location is not included in the ABS$CATALOG search list.
A catalog that is setup for staging improves the performance of the save operation because the
catalog entry for a saved file is first written to a sequential disk file in ABS$CATALOG. Once
the backup operation has completed a separate process moves the entries from the staging catalog
file to the final catalog which is specified in the archive associated with the save request.
The final catalog does not contain the information about the save operation until the staging process
has completed. If you request a backup operation and immediately look in the final catalog,
the entries may not be available, yet. The backup operation and the staging process must complete
before the currently saved files can be looked up in the catalog.
You can always modify the staging setting for an existing catalog. The use of staging is highly
recommended to improve your overall backup times.
The staging catalog file is created in the first location pointed to by logical name ABS$CATA-
LOG.
