This command provides a display of the status of the various classes of logical

locks that may be held in the system. Different classes of locks are held by internal

processes (SYS) or by NCL procedures (NCL).

Each resource may also have a text value associated with it. This value, used by

NCL lock processing, usually identifies the current holder of the lock and may be

queried by other NCL procedures which are competing for the same resource.

For related information, see the PURGE LOCK command.
