For the Connection Logic mode, the userID and password, passed from the CICS Adapter through the IBM CICS listener and into the Sun CICS Listener, must be defined for the z/OS security system (RACF, for example). The userID must be authorized by the z/OS security system to run CICS transaction “xxxx” inside of CICS. The default value for “xxxx” is STCL, and can be changed in the properties of the Connection Manager in the CICS Adapter.
