The following list describes all the tasks you must perform before you can begin using TMA TCP for CICS.

• Ensure that MVS TCP/IP is installed and configured.
• Ensure that the Sockets for CICS interface and supplied listener are installed and configured. The listener product comes with the Sockets for CICS interface.
• From the MVS TCP/IP administrator, find out at which port and address your supplied listener should listen. Give this information to the Oracle Tuxedo administrator so that the remote TMA TCP gateway component knows where to find the CICS TCP/IP listener.
• Find out on which ports TMA TCP gateway is listening. This information is necessary when you begin setting up services.
• Follow the installation instructions for TMA TCP given in the Oracle TMA TCP Installation Guide.
• Using the administration tool (described in Configuring and Administering Oracle TMA TCP for CICS) define the services and remote endpoints for use by TMA TCP. The best way to approach this is to talk to the Oracle Tuxedo administrator and choose one service only. Attempting to set up all the services at once would be a complex task, but after you learn how to set up one service, you should have no difficulty setting up the others.
• Add an EXEC LINK statement to one of your CICS programs and set up the data area as described in Understanding How Oracle TMA TCP for CICS Works.
• Consult your Oracle Tuxedo administrator about service names (what to call a service and what Oracle Tuxedo names it) and the layout of data each service expects to ensure there are no consistency problems.
