Create a Dynamic Cluster: Review
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.NameChanges 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.ClusterMessagingModeChanges 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.MulticastAddressChanges 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.MulticastPortMinimum value:
1Maximum value:
65535Changes 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.DynamicClusterSizeMinimum value:
0Maximum value:
800Server 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.ServerNamePrefixChanges take effect after you redeploy the module or restart the server.
Enable Calculated Listen Ports Specifies whether listen ports are calculated.
MBean Attribute:
DynamicServersMBean.CalculatedListenPortsChanges 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.CalculatedMachineNamesChanges 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.ListenPortMinimum value:
1Maximum value:
65535Administration Port The secure administration port for the server. This port requires that you enable the domain's administration port and that SSL is configured and enabled.
By default, the server uses the administration port that is specified at the domain level. To override the domain-level administration port for the current server instance, set this server's administration port.
MBean Attribute:
ServerMBean.AdministrationPortMinimum value:
0Maximum value:
65535Secure value:
7002
