Automatically assigning unique IDs using RACF commands
z/OS Security Server RACF Security Administrator's Guide
RACF® can automatically generate a unique ID value in the OMVS segment of a user or group upon your request. Do this by defining a profile called BPX.NEXT.USER in the FACILITY class (see Setting up the BPX.NEXT.USER profile) and then specifying the following command options:
Upon successful command completion, informational message IRR52177I is issued to indicate the assigned value.
For the ALTUSER and ALTGROUP commands, the AUTOUID and AUTOGID options cannot be used to change the ID value if one exists for the user. However, it is not considered an error if the existing ID is unique, meaning it is not shared. If it is not unique, the command fails and message IRR52178I is issued.
If you attempt to use the AUTOUID or AUTOGID option with a list of users or groups, the command will fail with message IRR52184I being issued.
