Create a Dynamic Cluster: Review

Configuration Options     

Use this page to review the configuration settings for the new dynamic cluster.

Configuration Options

Name Description
Name

The name of this dynamic cluster.

MBean Attribute:
ClusterMBean.Name

Changes take effect after you redeploy the module or restart the server.

Messaging Mode

Specifies the messaging type used in the cluster.

Multicast messaging is provided for backwards compatibility.

MBean Attribute:
ClusterMBean.ClusterMessagingMode

Changes take effect after you redeploy the module or restart the server.

Unicast Broadcast Channel

Specifies the channel used to handle communications within a cluster. If no channel is specified, the default channel is used.

Multicast Address

The multicast address used by cluster members to communicate with each other.

The valid range is from from 224.0.0.0 to 239.255.255.255. The default value used by WebLogic Server is 239.192.0.0. You should avoid using multicast addresses in the range x.0.0.1

This address should be unique to this cluster and should not be shared by other applications.

MBean Attribute:
ClusterMBean.MulticastAddress

Changes take effect after you redeploy the module or restart the server.

Multicast Port

The multicast port (between 1 and 65535) used by cluster members to communicate with each other.

Defines the multicast port used by cluster members to communicate with each other.

MBean Attribute:
ClusterMBean.MulticastPort

Minimum value: 1

Maximum value: 65535

Changes take effect after you redeploy the module or restart the server.

Number of Dynamic Servers

Get the current size of the dynamic cluster (the number of dynamic server instances allowed to be created). The specified number of server instances are dynamically added to the configuration at runtime and associated ServerLifeCycleRuntimeMBeans are created.

MBean Attribute:
DynamicServersMBean.DynamicClusterSize

Minimum value: 0

Maximum value: 800

Server Name Prefix

The server name prefix is used to specify the naming convention when creating server names. When the server name prefix is defined, server names are calculated with the specified prefix followed by the index starting with 1.

MBean Attribute:
DynamicServersMBean.ServerNamePrefix

Changes take effect after you redeploy the module or restart the server.

Enable Calculated Listen Ports

Specifies whether listen ports are calculated.

MBean Attribute:
DynamicServersMBean.CalculatedListenPorts

Changes take effect after you redeploy the module or restart the server.

Enable Calculated Machine Associations

The CalculatedMachineNames attribute controls how server instances in a dynamic cluster are assigned to a machine. If the attribute is not set, then the dynamic servers will not be assigned to a machine. If the attribute is set, then the MachineNameMatchExpression attribute is used to select the set of machines to use for the dynamic servers.

MBean Attribute:
DynamicServersMBean.CalculatedMachineNames

Changes take effect after you redeploy the module or restart the server.

Server Template

The name of the new server template created for this dynamic cluster.

Listen Port
SSL Listen Port

The TCP/IP port at which this server listens for SSL connection requests.

MBean Attribute:
SSLMBean.ListenPort

Minimum value: 1

Maximum value: 65535
