The LOCK function communicates with one Multi-User Facility. Be aware of the following:
Ensure that DBUTLTY is communicating with the desired Multi-User Facility by executing DBUTLTY with the same System Identifier module (DBSIDPR) that is being used by the Multi-User Facility, and
Ensure proper load library concatenation by keeping the System Identifier modules (DBSIDPR) in separate load libraries.
