DNS Configuration for Oracle Exadata Rack

1.10.2 DNS Configuration for Oracle Exadata Rack

Prior to receiving your Oracle Exadata Rack, you must use Oracle Exadata Deployment Assistant (OEDA) to generate files that drive the configuration of the system. The system configuration files contain network host names and IP addresses for the management network, client network, and additional public networks, which should be registered in Domain Name System (DNS) prior to initial configuration. In particular, all public addresses, single client access name (SCAN) addresses, and VIP addresses should be registered in DNS prior to 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 Oracle Exadata Database Machine. 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.

Note:

During configuration using OEDA, Grid Naming Service (GNS) is not configured on Oracle Exadata Database Machine.
