Dynamic clusters consist of server instances that can be dynamically scaled up to meet the resource needs of your application. A dynamic cluster uses a single server template to define configuration for a specified number of generated (dynamic) server instances. For more information about server templates, see Create server templates.
When you create a dynamic cluster, the dynamic servers are preconfigured and automatically generated for you, enabling you to easily scale up the number of server instances in your dynamic cluster when you need additional server capacity. For more information, see Dynamic Clusters.
Enter the multicast address of the new dynamic cluster in Multicast Address. A multicast address is an IP address in the range from 184.108.40.206 to 220.127.116.11. The default value used by WebLogic Server is 18.104.22.168. This address must be unique to this cluster and should not be shared by other applications.
Enter the multicast port for the new dynamic cluster in Multicast Port. The multicast port is used by cluster members to communicate with each other. Valid values are between 1 and 65535.
Server templates are used to configure the characteristics that are common to all the server instances in your dynamic cluster. If you do not have any server templates configured, one is automatically generated for you.
