6 JDBC GridLink Data Source Configuration (optional)
You can optionally configure the Oracle WebLogic Server GridLink data source to distribute database connections to Oracle RAC instances.
Before you create a multi-data source, edit the existing generic data source, create the generic data sources that the multi-data source will manage, and deploy them to the same targets where you want to deploy the multi-data source. You can create data sources and multi-data sources in a single edit session.
