Define an OMVS segment for TSO users

Start of changeTo 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®.End of change

Start of change
  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.
End of change

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.
