Adding a z/OS UNIX System Services segment

The user ID associated with the CICS®/TS region where z/OS® IP CICS Sockets is used requires a z/OS UNIX System Services segment. See the information in z/OS Security Server RACF Security Administrator's Guide and z/OS UNIX System Services Planning about defining groups and users, user profiles, and the OMVS segment in user profiles for more details about specifying a segment.
