In certain circumstances, some transactions have been migrated to ART/CICS on Linux, while some still reside on z/OS. This solution aims to build a bridge, through which applications in ART/CICS can invoke transactions on z/OS.

You can call an online transaction, referred to as main transaction hereinafter, provided by ART/CICS from 3270 terminal or a Tuxedo client through GWSNAX. To make the main transaction call a sub-transaction on z/OS, you need to follow these steps, which will be elaborated later:

• Step 1: Configuring ART CICS on Open System
• Step 2: Defining VTAM Resources
• Step 3: Configuring and Deploying TMA SNA
• Step 4: Start CRM on Mainframe
