SECURITY RESET (Clearing Security Validation Buffer) › When to Use

When to Use

Use the SECURITY RESET function to clear the security validation buffer. Security maintains a working set of validated profiles. This set is dynamically changed and is periodically cleared. If an access is changed, this reset must be done to ensure instant revalidation. This reset should be done only when changes have been made in your external security specifications that might be in the working set and, therefore, it is critical for the set to be refreshed.

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.

When using a console command, these steps are unnecessary.
