In this example, you would click on Cluster 1. Note that cluster was automatically named cluster-clu1 in the Cluster Name field, as shown in the following figure.
By default, a cluster name of cluster-clunumber will be assigned to the cluster (such as cluster-clu1). You may run into an issue with Enterprise Manager if you have multiple systems with the same default cluster names across the systems, so you must change the default cluster name to a unique name within your organization for the cluster (for example, organization-systemname-clusternumber, such as acme-osc01-clu1).
The Database Domains with zones are shown as ZHST in the left pane in the Define Clusters page. The Database Domains with zones that you selected appear in the right pane.
The following figure shows an example of a new cluster with all the Exadata Storage Servers assigned to that cluster.
The Cluster page for the first new cluster is displayed.
