With RACF® active, you have the option to define users through the RACF data base instead of through the UADS. Defining users through the RACF data base allows you to define users to TSO/E and RACF at the same time and eliminates the need to maintain two data sets for user information. Various RACF commands allow you to define users, maintain those definitions in the RACF data base, and remove users. For details about the RACF commands that define interactive users to TSO/E, see z/OS Security Server RACF Command Language Reference.

If your installation currently uses the UADS data set, you must first convert the UADS information to the RACF data base. Two TSO/E commands, RACONVRT and SYNC, assist installations in performing this conversion. The RACONVRT command converts user information to a format acceptable to RACF. The SYNC command or the SYNC subcommand of ACCOUNT synchronizes the RACF data base with the broadcast data set. For the syntax of the RACONVRT and SYNC commands, see z/OS TSO/E System Programming Command Reference.
