Authorizing CICS region userids to z/OS UNIX System Services

Some CICS® facilities require access to z/OS® UNIX System Services. These facilities are :

To ensure your CICS regions have the required access to z/OS UNIX system services, authorize the region userids by including an OMVS segment in the CICS region's user profile, specifying the UID parameter. In the OMVS segment, UID specifies the numeric user identifier.

When you are creating a new user profile for a CICS region userid:

For CICS region userids that already exist, add the OMVS segment information using the ALTUSER command. For example:

ALTUSER CICSHAA1 OMVS( UID(4127) HOME('/u/cicshaa1'))

where CICSHAA1 is the CICS region userid of a CICS AOR that is initialized with TCP/IP support, 4127 is the UNIX System Services numeric user identifier of the CICS region, and /u/cicshaa1 is the home directory.

For information about defining OMVS segment parameters in a user profile, see the z/OS Security Server RACF Command Language Reference, SA22-7687.
