Authorization verification mechanisms for the Backup and Recovery products and Utility products
The products use one of the following mechanisms to verify authorization:
If the DB2 DSNX@XAC authorization exit is available for your system, the product uses this exit to verify authorization for external access. The exit is available from the following sources:
IBM provides a sample exit with Db2 for the IBM Resource Access Control Facility (RACF) component.
CA Technologies provides the DSNX@XAC exit with the CA-ACF2 and CA-Top Secret products.
BMC recommends this mechanism for implementing external security. The access control authorization exit must be available in the STEPLIB, JOBLIB, linklist, or in the SYS3.DSN exit.
If the DSNX@XAC exit is not available, the product uses the standard Db2 method to check security.
