For information on setting up your TCP, see Defining a TCP connection.
The connection name (CONNAME) field in the channel definition to connect to your queue sharing group should be set to the generic interface of your queue-sharing group (see Generic interface). If you are using DNS/WLM, the generic interface is the name in DNSGROUP in your channel initiator parameters. If it is not set, it is the queue-sharing group name. For details of DNSGROUP, see WebSphere MQ for z/OS System Setup Guide.
Receiving shared channel programs are started in response to a startup request from the sending channel. To do this, a listener has to be started to detect incoming network requests and start the associated channel. You start this listener program with the START LISTENER command, using the inbound disposition of the group, or using the operations and control panels.
All group listeners in the queue-sharing group must be listening on the same port. If you have more than one channel initiator running on a single MVS image you can define virtual IP addresses and start your TCP listener program to only listen on a specific address or hostname by specifying IPADDR in the START LISTENER command. (For more information, see Chapter 33, Preparing WebSphere MQ for z/OS for DQM with queue-sharing groups.)
