Name The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration.MBean: weblogic.management.
configuration.ClusterMBeanAttribute: Name

Cluster Address Identifies the Managed Servers in the cluster. The cluster address is used in entity and stateless beans to construct the host name portion of URLs. If the cluster address is not set, EJB handles may not work properly. For production environments, cluster address should be a DNS host name that maps to the addresses of the Managed Servers in the cluster. For development environments, cluster address may be defined as 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: weblogic.management.
configuration.ClusterMBeanAttribute: ClusterAddress Configurable: yes
Default Load Algorithm The algorithm to be used for load-balancing clustered EJBs and RMI objects if no algorithm is specified for a particular object.MBean: weblogic.management.

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: weblogic.management.

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. Minimum: 0Maximum: 65534Default: 180Configurable: yesDynamic: yes
Client Cert Proxy Enabled When set to true for a cluster, this attribute specifies that certs from clients of web applications hosted on the server instances in the cluster are provided in the special WL-Proxy-Client-Cert header sent by a proxy plug-in or HttpClusterServlet. (ClientCertProxyEnabled can be defined at the cluster level, at the server level, and at the web application level, in web.xml.)This setting is useful if user authentication is performed on the proxy server - setting clientCertProxy to true causes the proxy server to pass on the certs to the cluster in a special header, WL-Proxy-Client-Cert. A WL-Proxy-Client-Cert header could be provided by any client with access to WebLogic Server. WebLogic Server takes the certificate information from that header, trusting that is came from a secure source (the plug-in) and uses that information to authenticate the user.For this reason, if you set clientCertProxy to true, use a connection filter to ensure that WebLogic Server accepts connections only from the machine on which the plug-in is running. See "Using Network Connection Filters in Programming WebLogic Security.MBean: weblogic.management.
