Create a Cluster: Cluster Properties
Use this page to set properties for a new 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.
Configuration Options
Name Description Name The name of this cluster.
MBean Attribute:
ClusterMBean.NameChanges take effect after you redeploy the module or restart the server.
Messaging Mode Specifies the messaging type used in the cluster.
Multicast messaging is provided for backwards compatibility.
MBean Attribute:
ClusterMBean.ClusterMessagingModeChanges take effect after you redeploy the module or restart the server.
Unicast Broadcast Channel Specifies the channel used to handle communications within a cluster. If no channel is specified, the default channel is used.
Multicast Address The multicast address used by cluster members to communicate with each other.
The valid range is from from 224.0.0.0 to 239.255.255.255. The default value used by WebLogic Server is 239.192.0.0. You should avoid using multicast addresses in the range x.0.0.1
This address should be unique to this cluster and should not be shared by other applications.
MBean Attribute:
ClusterMBean.MulticastAddressChanges take effect after you redeploy the module or restart the server.
Multicast Port The multicast port (between 1 and 65535) used by cluster members to communicate with each other.
Defines the multicast port used by cluster members to communicate with each other.
MBean Attribute:
ClusterMBean.MulticastPortMinimum value:
