In this example, the user catalog 387UCAT1 is disconnected from the system. Its cataloged objects are no longer available to users of the system.

//EXPORT3  JOB   ...
//STEP1    EXEC  PGM=IDCAMS
//SYSPRINT DD    SYSOUT=A
//SYSIN    DD    *
     EXPORT -
           G87UCAT -
           DISCONNECT
/*

The EXPORT command removes the user catalog connector entry for G87UCAT from the master catalog. The catalog becomes unavailable to system users until the system programmer reconnects it to the system, using an IMPORT CONNECT command. The parameters are:

• G87UCAT identifies the object to be disconnected.
• DISCONNECT identifies the object as a user catalog. When a user catalog's connector entry is to be deleted, DISCONNECT is required.
