z/OS IMS: IMS TCP/IP Direct Connect

TCP/IP support for z/OS IMS uses the CA Gen IMS TCP/IP Direct Connect product and IBM IMS Connect product on the z/OS machine. The IMS Connect product listens for input from the Client Manager. IMS Connect receives the input message and invokes a CA Gen message exit to start the IMS DPS application using IMS OTMA interface. When the DPS application processing is complete, a response message is passed back to IMS Connect that returns it to the Client Manager and on to the DPC application.

The hardware and software vendor documentation assists in the setup and testing for communications with TCP/IP.
