Oracle Clusterware 11g release 2 (11.2) introduced server pools, where resources that Oracle Clusterware manages are contained in logical groups of servers called server pools. Resources are hosted on a shared infrastructure and are contained within server pools. Examples of resources that Oracle Clusterware manages are database instances, database services, application VIPs, and application components.
In an Oracle Flex Cluster, with Hub Nodes and Leaf Nodes, you can use server pools to run particular types of workloads on cluster member nodes, while providing simplified administration options. You can use a cluster configuration policy set to provide dynamic management of cluster policies across the cluster.

You can continue to manage resources in an Oracle Clusterware standard Cluster by using the Oracle Clusterware 11g release 2 (11.2) server pool model, or you can manually manage resources by using the traditional fixed, non-server pool method.
