Required Parameters

usercatname

names the user catalog to be disconnected. This parameter must be the first parameter following EXPORT. When you are disconnecting a user catalog, you must supply the alter authority to the catalog from which the entry is being removed. See Catalog Selection Order for EXPORT DISCONNECT for the order in which a catalog is selected.

If the user catalog is SMS-managed, its volume serial number is indicated at the time of disconnect.

CATALOG(catname)

specifies, for a disconnect operation, the name of the user catalog from which a user catalog connector entry and any associated alias entries are to be deleted. See Catalog Selection Order for EXPORT DISCONNECT for the order in which a catalog is selected when the CATALOG parameter is not specified. The CATALOG parameter is required when you want to direct the catalog's entry to a particular catalog other than the current master catalog on the system you are running this command on.

catname/alias: Names the catalog or an alias that can be resolved to a catalog. For example, if alias ABCD relates to catalog SYS1.USERCAT, then specifying either ABCD or SYS1.USERCAT will cause the catalog to be disconnected from catalog SYS1.USERCAT.

Abbreviation: CAT

DISCONNECT

specifies that a user catalog is to be disconnected. The connector entry for the user catalog is deleted from the master catalog. Also, the user catalog's alias entries are deleted from the master catalog.

If EXPORT is coded to remove a user catalog connector entry, DISCONNECT is a required parameter. The VVDS volume and the BCS volume can be physically moved to the system to which the catalog is connected.

To make a user catalog available in other systems and in the original system, code the IMPORT CONNECT command to connect the user catalog to each system to which it is to be available, but do not EXPORT DISCONNECT the user catalog.

EXPORT DISCONNECT displays the volume serial number of the user catalog at the time of the disconnect. This volume serial number information is required to perform the IMPORT CONNECT.

Abbreviation: DCON
