ZCFLK DELETE-Remove a Coupling Facility from the Coupling Facility Locking Configuration

Use this command to remove a coupling facility (CF) from the CF locking configuration. All locks stored on this CF are redistributed automatically among the remaining CFs in the CF locking configuration on a module-by-module basis. As a result, locks can no longer be stored on this CF.

Requirements and Restrictions

You can enter this command only when the CF you want to remove from the CF locking configuration is not the last CF defined in the CF locking configuration.

If the CF is the last one defined in the CF locking configuration and at least one module is using CFs for locking, the lock residency for all affected modules must be migrated back to the locking control units (CUs). You can do so by using the ZCFLK MIGRATE command. If you are migrating an online module, the duplicate module is also migrated. You can then enter the ZCFLK DELETE command to remove the CF from the locking configuration.

Format




cfname
is the 5- to 8-character alphanumeric name of the CF you want to remove from the CF locking configuration. The first character of the CF name must be an alphabetic character.
