The Connection Name attribute identifies the communications link to be used by this channel; it is required for sender channels, requester channels, client-connection channels, and cluster-sender channels.
The Connection Name attribute is optional for server channels, or cluster-receiver channels using TCP.
For cluster-receiver channels using TCP, the value of the Connection Name attribute is the address of the computer that hosts the queue manager and the port. If the Connection Name attribute is left blank, the default port (1414) is used, with the current IP address of the computer.
This test is only valid for TCP channels.
The test could not resolve a host name (specified in the Connection Name attribute of the channel) to the associated IP address.
This situation could be caused because the host name is not specified correctly, or because a name server is unavailable.
