Sample configuration of System/390 and non-System/390 CICS systems

The picture shows the configuation described on the previous page. It shows an ASCII system (CICS Transaction Server for Windows or CICS on Open Systems) and four CICS System/390 systems. The CICS on System/390 systems comprise:

The TOR is connected to both AORs and to the DOR. The DOR is connected to both AORs and to the TOR. The AORs are connected to the TOR and the DOR but not to each other.

The ASCII system has an LU 6.2 link to three of the CICS on System/390 systems: link X to TOR, link Y to AOR1, and link Z to DOR.
