This figure shows the OAAM high availability configuration architecture. In the figure, a load balancer routes requests through two Oracle HTTP Server instances on WEBHOST1 and WEBHOST2 to OAAMHOST1 and OAAMHOST2. An OAAM Administration Server instance and an OAAM Managed Server instance is installed on OAAMHOST1 and on OAAMHOST2. These installations are configured as an OAAM Server cluster (OAAM_SERVER_CLUSTER), an OAAM_OFFLINE cluster, and an OAAM Admin Cluster (OAAM_Admin_Cluster). The OAAM Server cluster uses the OAAM Server data source and the OAAM Admin cluster uses the OAAM Admin data source to communicate with the Oracle RAC database.
