Before two systems can communicate, they each need to know:
This chapter shows how you specify that information when configuring CICS® systems for SNA communication.
There are a number of stages in the process of configuring a system for communication:
This chapter gives you the information on SNA and CICS that you will need to establish that first basic configuration. You should not consider proceeding beyond that first stage until you have completed and successfully tested a basic, simple SNA connection.
There are other manuals that give broader and more detailed information about SNA. There are manuals that explain the SNA architecture, manuals that explain how individual products have implemented the architecture, and manuals that explain how to configure various combinations of different systems. There is a list of useful books in SNA books.
The scenario chosen for the discussion is based on an established SNA network of interconnected CICS on System/390® systems. To this we will be adding a CICS for AIX® system, which will use SNA to connect to one of the CICS on System/390 systems.
