Overview

A WebLogic Server cluster is a group of servers that work together to provide a more scalable, more reliable application platform than a single server.
Use this page to specify a server's primary and secondary replication group, cluster weight, and the interface address used to handle multicast traffic.

Description

Value Constraints
Replication Group Defines preferred clustered instances considered for hosting replicas of the primary HTTP session states created on the server.MBean: weblogic.management.
configuration.ServerMBeanAttribute: ReplicationGroup

Preferred Secondary Group Defines secondary clustered instances considered for hosting replicas of the primary HTTP session states created on the server.MBean: weblogic.management.
configuration.ServerMBeanAttribute: PreferredSecondaryGroup

Cluster Weight Defines a value used specify the proportion of the load the server will bear relative to other servers in a cluster.If all servers have the default weight (100) or the same weight, each bears an equal proportion of the load. If one server has weight 50 and all other servers have weight 100, the 50-weight server will bear half as much load as any other server.MBean: weblogic.management.

Interface Address The interface address used to specify the NIC that handles cluster multicast traffic.MBean: weblogic.management.
