Policy-Managed Clusters and Capacity Management

Review this information about policy-managed clusters.

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. Resources are no longer defined as belonging to a specific instance or node. Instead, the priority of resource requirements is defined.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.
