Establishing a TCP connection

TCP connections do not require the configuration of additional profiles as does the LU 6.2 protocol. Instead, MQSeries for VSE/ESA processes the listener program during startup.

The listener program waits for remote TCP connection requests. As these are received, the listener starts the receiver MCA to process the remote connection. When the remote connection is received from a client program, the receiver MCA starts the server program.

Note:

There is one server process for each client connection.

Provided that the listener is active and TCP is active in a VSE partition, TCP connections can be established.
