Novice CA Automation Point (AP) users often inquire about HOW-TO setup a TN3270 session connection between AP and a mainframe host for communication. This document describes the prerequisites and the details of setting up a TN3270 session for monitoring and automating a mainframe host console.


Before you can establish communications between AP and your IBM or IBM-compatible mainframe host, you must configure a communication server that supports TN3270 (such as OSA Integrated Console Controller (OSA-ICC) or IBM 2074 Console Controller) to host either operating consoles or VTAM applications using TN3270E connections through IBM 3278/3279 model 2,3,4 or 5 display terminals.

Note: For a 3270 session defined to AP to properly connect to a z/OS console, the console must also be defined to the mainframe host. A z/OS console is defined on the mainframe host in member CONSOLxx in the SYS1.PARMLIB library, where the xx in the CONSOLxx is the value of the CON parameter in member IEASYS00.
