Connecting to a Mainframe: Overview

The configuration described in this section uses an SNA link between CICS applications running on a mainframe and CICS operating on a local COBOL system, that is one that operates on one or more local Windows or UNIX machines.

Note:

This functionality allows Enterprise Server to connect to a remote peer system using a SYS62 connection and support the standard 2-Phase Commit protocol.

One of the benefits that this functionality provides is that it improves transactional data integrity between CICS applications running on a UNIX platform, and CICS applications running on a mainframe under z/OS.

CICS Communications with mainframe CICS regions using SYS62 connections have been tested with z/OS version 1.13.

To configure a link between Enterprise Server and Mainframe CICS regions, you should be familiar with:

The concepts of a CICS system, and how it can operate over multiple machines in a single system environment
CICS intersystem communication requirements.
Configuring the communications software on the local server.
Configuring the communications software on the client.
