Resources (e.g., files) whose specific names have been defined in the operating system can be put under lock. Give a unique name in the node to a user-specific resource. OpenTP1 cannot judge if the name of the resource to be put under lock is correct. Specify the correct resource name in the UAP.

Lock can be specified in only the same node in an OpenTP1 system. Lock with a UAP in another OpenTP1 system cannot be specified.
