Running the example for z/OS
When we have created the required objects, you must start the channel initiators and listeners for both queue managers.
The applications can then send messages to each other. Because the channels are triggered to start by the arrival of the first message on each transmission queue, we do not need to issue the START CHANNEL MQSC command.
For details about starting a channel initiator see Starting a channel initiator, and for details about starting a listener see Starting a channel listener.
