Using the RACF data base to maintain TSO/E users

If RACF® is installed, the information that is required for users to log on to TSO/E can be stored in the RACF data base. You can convert user information defined in the UADS to the RACF data base and use the RACF data base to maintain TSO/E users. You can convert user information for all TSO/E users, or only selected users. TSO/E retrieves user information from the UADS for any user IDs that are not converted to the RACF data base.

Using the RACF data base to maintain TSO/E users has several advantages:

Simplified maintenance of user ID information
You can maintain TSO/E users and allow them to use the RACF security functions without having to use TSO/E and RACF commands to update the UADS, and use RACF commands to update the RACF data base. Adding, changing and deleting user ID information is simpler using the RACF data base because you use only RACF commands.

Recommendation: For recovery purposes, you should keep a minimal set of user IDs. For additional information, see Maintaining UADS for recovery mode.
