**********************************************************************

In this example, all catalogs except the master catalog reside on SMS-managed volumes. All but two use the catalog data space (VLF) cache.

Explanations for the output are as follows:

FLAGS

The flags have the following meanings:

Y/N: The catalog is (Y) or is not (N) allocated to the catalog address space.
S: The catalog is managed by the Storage Management Subsystem.
V: The catalog is using the catalog data space cache (VLF).
I: The catalog is using the in-storage catalog.
C: The catalog is closed.
D: The catalog has been deleted.
R: The catalog is using cross systems sharing.
A: The catalog is a tape volume catalog.
E: The catalog is shared and is using the Enhanced Catalog Sharing facility.
K: The catalog has been locked by an IDCAMS ALTER LOCK or IMPORT LOCK command.

VOLSER

The VOLSER field shows the volume serial number of the volume containing the catalog.

USER

The USER field contains a count of the number of address spaces that have allocated this catalog. This Catalog Address Space number is normally one.

%

The % column shows the percentage of allocated extents for each catalog in the list. This percentage indicates the extent usage by either the data or index component, whichever is higher, for that particular catalog. For catalogs that are marked as closed or deleted, this value is N/A.
