User Profile Requirements

The CICS region started task must have a unique user ID assigned by the RACF STARTED class or the ICHRIN03 started procedure table.

The user ID assigned must have a valid z/OS Unix security context, or OMVS segment, in both the user ID profile and group profile. This can be accomplished by defining OMVS segments for the assigned user ID and group, or by utilizing the BPX.DEFAULT.USER FACILITY class profile. It is good practice to avoid running the associated started tasks as either privileged or trusted if you are using the BPX.DEFAULT.USER FACILITY class profile.
