This page allows you to define the general settings for this cluster.

Configuration Options

Name	Description
Name	The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration. MBean Attribute: ClusterMBean.Name Changes take effect after you redeploy the module or restart the server.
Default Load Algorithm	Defines the algorithm to be used for load-balancing between replicated services if none is specified for a particular service. The round-robin algorithm cycles through a list of WebLogic Server instances in order. Weight-based load balancing improves on the round-robin algorithm by taking into account a pre-assigned weight for each server. In random load balancing, requests are routed to servers at random. MBean Attribute: ClusterMBean.DefaultLoadAlgorithm
Cluster Address	The address that forms a portion of the URL a client uses to connect to this cluster, and that is used for generating EJB handles and entity EJB failover addresses. (This address may be either a DNS host name that maps to multiple IP addresses or a comma-separated list of single address host names or IP addresses.) Defines the address to be used by clients to connect to this cluster. This address may be either a DNS host name that maps to multiple IP addresses or a comma separated list of single address host names or IP addresses. If network channels are configured, it is possible to set the cluster address on a per channel basis. MBean Attribute: ClusterMBean.ClusterAddress Changes take effect after you redeploy the module or restart the server.
Number Of Servers In Cluster Address	Number of servers to be listed from this cluster when generating a cluster address automatically. This setting has no effect if Cluster Address is explicitly set. MBean Attribute: ClusterMBean.NumberOfServersInClusterAddress Minimum value: 1 Changes take effect after you redeploy the module or restart the server.
Enable Transaction Affinity	If enabled, a server's transaction requests go to servers in the cluster that are already participating in the global transaction. MBean Attribute: ClusterMBean.TxnAffinityEnabled Changes take effect after you redeploy the module or restart the server.

Advanced Configuration Options

Name	Description
WebLogic Plug-In Enabled	Set this attribute to true if the cluster will receive requests from a proxy plug-in or HttpClusterServlet. When WeblogicPluginEnabled is true, a call to getRemoteAddr will return the address of the browser client from the proprietary WL-Proxy-Client-IP header, instead of the Web server. For non-clustered servers that will receive proxied requests, this attribute may be set at the server level, on the Server -->Configuration-->General tab. WeblogicPluginEnabled is duplicated both in ClusterMBean and ServerMBean. ClusterMBean overrides ServerMBean. MBean Attribute: ClusterMBean.WeblogicPluginEnabled Changes take effect after you redeploy the module or restart the server.
Service Age Threshold	The number of seconds by which the age of two conflicting services must differ before one is considered older than the other. MBean Attribute: ClusterMBean.ServiceAgeThresholdSeconds Minimum value: 0 Maximum value: 65534
Member Warmup Timeout	Maximum number of seconds that a cluster member will wait to discover and synchronize with other servers in the cluster. Normally, the member will be able to sync in 30 seconds. If the value of this attribute is higher, that does not necessarily mean that it will take longer for the member to warmup. Instead it defines an upper bound on the time that a server will wait to sync with the servers that it has discovered. If the value is set 0, servers will not attempt to discover other running server in the cluster during server initialization MBean Attribute: ClusterMBean.MemberWarmupTimeoutSeconds Minimum value: 0
