To prevent duplication, only one or two administrators should assign UIDs and GIDs. To manage UID and GID assignments, do one of the following:

• Use AUTOGID or AUTOUID keywords to have UIDs and GIDs automatically assigned to the user. These are keywords on RACF® commands that you use to define users and groups. This is the suggested method.
• Use the RACF database unload utility to move RACF data into a DB2® database and then use the Structured Query Language (SQL) to query the database.
• Use the ISPF shell to perform the tasks of defining users and groups.
