Cluster Multicast Address and Port
Identify the address and port you will dedicate to multicast communications for your cluster. A multicast address is an IP address between 224.0.0.0 and 239.255.255.255.
Note: The default multicast value used by WebLogic Server is 239.192.0.0. You should not use any multicast address with the value x.0.0.1.
Server instances in a cluster communicate with each other using multicast?athey use multicast to announce their services, and to issue periodic heartbeats that indicate continued availability.
The multicast address for a cluster should not be used for any purpose other than cluster communications. If the machine where the cluster multicast address exists hosts or is accessed by cluster-external programs that use multicast communication, make sure that those multicast communications use a different port than the cluster multicast port.
Multicast and Multiple Clusters
Multiple clusters on a network may share a multicast address and multicast port combination if necessary.
Multicast and Multi-Tier Clusters
If you are setting up the Recommended Multi-Tier Architecture, described in Cluster Architectures, with a firewall between the clusters, you will need two dedicated multicast addresses: one for the presentation (servlet) cluster and one for the object cluster. Using two multicast addresses ensures that the firewall does not interfere with cluster communication.
