UNLOCK (Unlock a Data Area) › When to Use

When to Use

Use the UNLOCK function to reverse a LOCK function.

This function communicates with one MUF. Be aware of the following:

• Ensure that DBUTLTY is communicating with the desired MUF by executing DBUTLTY with the same System Identifier module (DBSIDPR) that is being used by the MUF
• Ensure proper load library concatenation by keeping the System Identifier modules (DBSIDPR) in separate load libraries

If the z/OS Cross-System Coupling Facility (XCF) is being used, ensure that the TOGROUP DBSIDPR parameter is correctly defined. See the CA Datacom/DB Database and System Administration Guide for more information on XCF.
