Clusters: Create a Dynamic Cluster
This page allows you to set properties for a new dynamic cluster.
Clusters use messaging for sharing session, load balancing and failover, JMS, and other information between cluster members. Clusters can use either unicast or multicast messaging. Multicast is a simple broadcast technology that enables multiple applications to subscribe to a given IP address and port number and listen for messages, but requires both network and hardware configuration and support. Unicast provides the same type of communication within a cluster, but does not have these requirements.
Multicast is the default messaging method to support backward compatibility. However, it is recommended that you use unicast when creating new clusters.
