You can optionally configure the 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.
