Obtaining the CICS region user ID

For the purposes of MRO logon and connect security checks, DFHIRP needs to know the CICS® region user ID under which the CICS job or task is running. DFHIRP obtains the CICS region's user ID by issuing a RACROUTE REQUEST=EXTRACT macro.

If you are not using RACF® as your external security manager, you must use the MVS security router exit, ICHRTX00, to customize the response from the RACROUTE REQUEST=EXTRACT macro.

CICS determines whether a security manager is present or not by examining the SAF response codes.
