The following properties are used to configure the cluster connection service used for internal communication between brokers in the cluster. These properties are used by both conventional and high-availability clusters.
imq.cluster.transport specifies the transport protocol used by the cluster connection service, such as tcp or ssl.
imq.cluster.port specifies the port number for the cluster connection service. You might need to set this property, for instance, to specify a static port number for connecting to the broker through a firewall.
imq.cluster.hostname specifies the host name or IP address for the cluster connection service, used for internal communication between brokers in the cluster. This setting can be useful if there is more than one network interface card installed in a computer.
