Oracle Net Services Configuration for Oracle RAC Databases

You can access an Oracle RAC database using a client and server configuration or through one or more middle tiers, with or without connection pooling.

When connecting to an Oracle Database, you can use a connect descriptor or a net service name. For Oracle RAC databases, you can also use the Single Client Access Name (SCAN) to connect to any available instance of the Oracle RAC database.
