Registering Recovery Appliance in the Domain Name System

Before receiving your Recovery Appliance rack, use Oracle Exadata Deployment Assistant. The assistant generates a file to be used when setting up the system. The host names and IP addresses specified in the assistant-generated file must be registered in Domain Name System (DNS) before the initial configuration. In addition, all public addresses, single client access name (SCAN) addresses, and VIP addresses must be registered in DNS before installation.

The assistant-generated file defines the SCAN as a single name with three IP addresses on the client access network. The three SCAN addresses provide service access for clients to Recovery Appliance. Configure DNS for round robin resolution for the SCAN name to these three SCAN addresses.

All addresses registered in DNS must be configured for both forward resolution and reverse resolution. Reverse resolution must be forward confirmed (forward-confirmed reverse DNS) such that both the forward and reverse DNS entries match each other.
