CSD UNLOCK

Description

The UNLOCK command removes from a group or list a lock previously added by the LOCK command.

A syncpoint is implicit in CSD UNLOCK processing, except when an exception condition is detected early in processing the command. Uncommitted changes to recoverable resources made up to that point in the task are committed if the command is successful, and rolled back if not.
