Define an OMVS segment for TSO users

To communicate with the CICS® Configuration Manager server, the CICS Configuration Manager clients use TCP/IP socket functions that are provided by z/OS® UNIX System Services (via Language Environment®). The TSO user IDs that invoke the CICS Configuration Manager clients must have permission to execute the underlying z/OS UNIX BPX* programs that implement these functions. To control permissions for these programs, z/OS uses OMVS segments in RACF®.

  1. Define an OMVS segment in RACF for the TSO user IDs that invoke CICS Configuration Manager clients.
  2. Allow the TSO user IDs to execute BPX* programs.

If the user has insufficient access, then Language Environment issues the following run-time message (for the batch client, this message appears in the CEEMSG data set):

CEE5101C During initialization, the callable service BPX1MSS failed.
         The system return code was 0000000156 , the reason code was 0B0C00FC .
         The application will be terminated.

and the client application abends.

For more information about the OMVS segment, see z/OS: Security Server RACF Security Administrator's Guide and z/OS: UNIX System Services Planning.
