3.3.4 Choosing the Cluster Database Management Type

When creating an Oracle RAC database, you can choose one of two types of databases to create.

• A policy-managed database: The database instances are automatically managed based on server pools for effective resource utilization.

  Starting with Oracle Grid Infrastructure 21c, policy-managed databases are deprecated.

  You can continue to use existing server pools, and create new pools and policies. Resources using existing server pools can continue to use them transparently.

  The use of CRS configuration policies and the CRS policy set can be desupported in a future release. In place of server pools and policy-managed databases, Oracle recommends that you use the new "Merged" management style.

• An administrator-managed database: The database instances are tied to specific servers in the cluster.
