This topic describes tasks related to working with and maintaining the RACF® database using the database unload utility (IRRDBU00) and the remove ID utility (IRRRID00).

For information about using the SMF data unload utility (IRRADU00), see z/OS Security Server RACF Auditor's Guide.

The RACF database holds an installation's security data. This data is used to control access to resources, verify users, and generate a variety of reports dealing with system usage and integrity. Standard reports are provided and used to determine whether the installation's security objectives are being met.
