This image shows a DataSource and MultiDataSource configuration.

The application server (http://SRVRCHOSA1:8004) is connected to four MultiDataSources. Each MultiDataSource is connected to two corresponding DataSources.

Each Data Source in a set is connected to one RAC node ( SRVRCHDVRAC1-VIP or SRVRCHDVRAC2-VIP).

Both RAC nodes are connected to the clustered machine.
