IRRUT100 is a RACF® utility program that lists certain occurrences of a user ID or group name in a RACF database. It uses the RACF manager to access the RACF database and locate possible occurrences of a user ID or group name.

IRRUT100 provides information on the occurrences described in Group name and user ID occurrences that IRRUT100 lists. IRRUT100 does not list all occurrences in the RACF database.

An alternative to using IRRUT100 is to use the database unload utility, IRRDBU00. It provides a sequential file of the database that an installation can manipulate to obtain additional and more complex reports.

Guideline: Use the IRRDBU00 and IRRRID00 utilities to keep user ID and group information current in the RACF database.

For more information on IRRDBU00 and IRRRID00, see z/OS Security Server RACF Security Administrator's Guide and z/OS Security Server RACF Macros and Interfaces.

To invoke IRRUT100, you must be a RACF-defined user and either have the SPECIAL, group-SPECIAL, AUDITOR, or group-AUDITOR attributes, or be requesting a list of occurrences for only your user ID.

Although IRRUT100 must read every user and group profile in your database, it obtains and releases database serialization for each profile being read. Thus, the database is accessible, depending on the performance options set at your installation and other ongoing system activity.

IRRUT100 produces a cross-reference report that describes the following occurrences of each user ID or group name specified. In the output, the letter G in parentheses follows each generic profile name. See Figure 1 for a sample output of the printed report that IRRUT100 produces.
