There are the following two methods for releasing a resource with lock specified:

• A resource is released from lock by the UAP shutting down the resource. To release a resource from lock by specifying the name of the resource, call the function dc_lck_release_byname() [CBLDCLCK('RELNAME ')]. To release all the resources shut down by the UAP at a time, call the function dc_lck_release_all() [CBLDCLCK('RELALL ')].

The lock release functions can be called only from the UAP that specified lock for the resource. OpenTP1 allocates the resource released from lock to a UAP waiting for the resource.

• After the synchronization point processing of the UAP that shuts down the resource, OpenTP1 deallocates all the resources being shut down by the UAP. OpenTP1 automatically deallocates the resources regardless of whether the UAP terminates normally or abnormally.
