Name

The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration.

MBean: weblogic.management.
configuration.ClusterMBean

Attribute: Name

Cluster Address

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: weblogic.management.
configuration.ClusterMBean

Attribute: ClusterAddress

Configurable: yes

Default Load Algorithm

The algorithm to be used for load-balancing between replicated services if none is specified for a particular service.

MBean: weblogic.management.
configuration.ClusterMBean

Attribute: DefaultLoadAlgorithm

Default: "round-robin"

Valid values:

• "round-robin"

• "weight-based"

• "random"

• "round-robin-affinity"

• "weighted-affinity"

• "random-affinity"

Configurable: yes

WebLogic Plug-In Enabled

WLS HttpRequest.getRemoteAddr() used to rely on X-Forwarded-For for its returned value. This is a security hole due to HTTP header can be easily mocked and we end up with returning wrong value. This is improved by introducing a proprietary header WL-Proxy-Client-IP from our plugins and this header will only be used if WLS is configured to use our plugins. This is duplicated both in ClusterMBean and ServerMBean so the attribute WeblogicPluginEnabled can be used cluster-wide. ClusterMBean overrides ServerMBean

MBean: weblogic.management.
configuration.ClusterMBean

Attribute: WeblogicPluginEnabled

Default: false

Valid values:

• true

• false

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: 0

Maximum: 65534

Default: 180

Configurable: yes

Dynamic: yes

Client Cert Proxy Enabled

Defines if the HttpClusterServlet proxies the client certificate in a special header.

It's strongly suggested to use in conjunction with ConnectionFilters to make certain the WebLogic proxy machine is the only connection.

MBean: weblogic.management.
configuration.ClusterMBean

Attribute: ClientCertProxyEnabled

Default: false

Valid values:

• true

• false
