Overview
Deleting RACF users and groups is generally not as straightforward as simply deleting a profile because other profiles in the RACF database may refer to the user or group. For example:
-
Dataset profiles may exist that have the user ID (UID) or group ID (GID) as their high level qualifier.
-
The group or user may be the owner of other profiles (for example, user profiles, group profiles, or resource profiles).
-
The user or group may be authorized to access resources, and therefore appear in the resources’ access lists.
-
The group may still have subgroups or users connected to it.
Some of the above conditions prevent the deletion of a user or group. Others do not prevent the deletion, but leave the RACF database with redundant information after the user or group is deleted.
RACF cross-reference utility IRRUT100 can be used to find all occurrences of a UID or GID in the RACF database. This utility, however, does not delete the user ID or group ID occurrences from the database.
