Exadata Database on Dedicated Infrastructure: Private DNS

Allow users to choose the private view and private zone while provisioning a new VM cluster for ExaCS. All the underlying resources of the VCN, including those of ExaDB-D, should be created in the same private zone. The private zones can be associated with subnets inside the VCN. This configuration cannot be changed later.

Private DNS resolver is going to resolve queries in customer VCN and queries coming from the on-premise networks. Ability to provide the DNS address and seed that into DB resources using conditional forwarding, is provided by the private DNS feature. With a private resolver, customers can resolve the A-record across different VCNs (with VCN peering- local/remote).
