Explanation:
Because policy-managed configuration was selected, the server pool to host the new CDB must be defined. Choose between using an existing server pool or creating a new one and specifying the detail of the new server pool to be used by the CDB.
Policy-managed deployments facilitate consolidation. In the case of schema consolidation, where multiple applications are being hosted in a single database (CDB) separated into PDBs, since server pools determine which services run together or separately, you can configure and maintain required affinity or isolation of PDB services.
Managing a policy-managed database requires less configuration and reconfiguration steps than an administrator-managed one with respect to creation, sizing, patching, and load balancing. Also, because any server in the server pools within the cluster can run any of the CDB instances and PDB services, you do not have to create and maintain CDB instance-to node-name mappings and PDB service-to-node-name mappings.
