The specification for the channel, in the following form:
Here channel_name is the name of the channel to use, transport is the transport used by the channel, host_name is the server name (or IP address) that is running the IBM WebSphere MQ server, and port is the port that this channel should use.
Transport can be one of the following: TCP, LU62, NETBIOS, SPX
If you omit this setting, the system uses the default channel specification, as configured in IBM WebSphere MQ. Or, if the system has been the configured so that the channel is determined by the queue name, the system uses the channel that is appropriate for the given queue name.
