This figure shows an Oracle RTD high availability active-active architecture. A load balancer receives requests from the internet and distributes them between WEBHOST1 or WEBHOST2. Both WEBHOSTs contain Oracle HTTP Server (OHS).

Across a firewall, separate boxes labeled APPHOST1 and APPHOST2 are connected by a WLS Cluster containing BI_SERVER1 and BSERVER2. Each server contains RTD.

Both APPHOSTs have an Admin Server, but the Admin Server for APHOST2 is deactivated and. APPHOST1 also contains a green bubble labeled VIP0.

An arrow indicates that data from the WLS Cluster crosses the firewall into the data tier. The arrow intersects with a green bubble labeled VIP. The arrow ends at a cluster of discs labeled Oracle RAC Database. Above the clusters is a bulleted list containing the items RTD Repository and Enterprise Database.
