Configuration Options Related Tasks Related Topics
Use this page to define a cluster configuration for this server. A WebLogic Server cluster is a group of servers that work together to provide a scalable and reliable application platform.
Configuration Options
Name Description Replication Group Defines preferred clustered instances considered for hosting replicas of the primary HTTP session states created on the server.
MBean Attribute:
ServerMBean.ReplicationGroupChanges take effect after you redeploy the module or restart the server.
Preferred Secondary Group Defines secondary clustered instances considered for hosting replicas of the primary HTTP session states created on the server.
MBean Attribute:
ServerMBean.PreferredSecondaryGroupChanges take effect after you redeploy the module or restart the server.
Cluster Weight The proportion of the load that this server will bear, relative to other servers in a cluster.
If all servers have the default weight 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 Attribute:
ServerMBean.ClusterWeightMinimum value:
1Maximum value:
100Changes take effect after you redeploy the module or restart the server.
Interface Address The IP address of the NIC that this server should use for multicast traffic.
MBean Attribute:
ServerMBean.InterfaceAddressChanges take effect after you redeploy the module or restart the server.
Replication Ports When WLS is running on Exalogic machines, cluster replication traffic could go over multiple replication channels. However multiple replication channels need not be configured on each clustered server instance. Only one replication channel with explicit IP-Address needs to be configured for each server and replicationPorts range can be specified for each server. For eg. range 7001-7010 will create 10 replication channels with ports 7001 to 7010 for the given server. These channels inherits all the properties of the configured replication channel except the listen port.Names of these channels will be derived from the configured replication channel with suffic {x} added where x could be 1,2.. as per the number of ports specified. Public ports are same as the listen port for these additional channels.
MBean Attribute:
ServerMBean.ReplicationPortsChanges take effect after you redeploy the module or restart the server.
