You can use the createDynamicCluster.jacl script to create a dynamic cluster.
Although you can still use the Jacl scripts to create and delete dynamic clusters, the administrative tasks provide all of the options that are available for configuring dynamic clusters in Version 6.1 and later. See Dynamic cluster administrative tasks for more information.
wsadmin -profile createDynamicCluster.jacl node_group_name dynamic_cluster_nameIn place of node_group_name and dynamic_cluster_name use the name of the node group that you want to associate with your new dynamic cluster. You might need to modify the wsadmin command to wsadmin.sh or wsadmin.bat, depending upon your operating environment.
The code in the runtime creates a membership policy when you create your dynamic cluster. For example, if you indicate the node_group_1 node group, the membership policy of node_nodegroup='node_group_1' is created.
