Communicating With Mainframe Host Using TN3270

Before you can establish communications between CA Automation Point 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 CA Automation Point 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.PAEMLIB library, where the xx in the CONSOLxx is the value of the CON parameter in member IEASYS00.

TN3270E terminal emulation is native to CA Automation Point.  Using Configuration Manager, you must also configure corresponding TN3270E connection settings and terminal display emulation for each mainframe host session you wish CA Automation Point to establish.  Console type, when applicable, must also be specified for each defined 3270 session to enable built-in console drivers to manage the session accordingly. 

Note: For faster message processing and better action message handling by CA Automation Point, we recommend that you configure 3270 console sessions for IBM 3278/3279 model 4 terminal emulation.
