Architecture Notes Understanding the Application Tier

Enterprise Deployment Overview 1-11 ■ In the OAM and OIM topology, OIMHOST1 and OIMHOST2 have Oracle Identity Manager and Oracle SOA installed. Oracle Identity Manager is user provisioning application. Oracle SOA deployed in this topology is exclusively used for providing workflow functionality for Oracle Identity Manager. ■ In the OAAM topology, OAAMHOST1 and OAAMHOST2 have the WebLogic Server with the Oracle Adaptive Access Manager Server and Console installed. ■ OIFHOST1 and OIFHOST2 have the WebLogic Server with Oracle Identity Federation installed.

1.5.2.1 Architecture Notes

■ Oracle Enterprise Manager Fusion Middleware Control is integrated with Oracle Access Manager using the Oracle Platform Security Services OPSS agent. ■ The Oracle WebLogic Server console, Oracle Enterprise Manager Fusion Middleware Control, and Oracle Access Manager console are always bound to the listen address of the Administration Server. ■ The administration server is a singleton service. It runs on only one node at a time. In the event of failure, it is restarted on a surviving node. ■ The WLS_ODS1 Managed Server on IDMHOST1 and WLS_ODS2 Managed Server on IDMHOST2 are in a cluster and the Oracle Directory Services Manager and Oracle Directory Integration Platform applications are targeted to the cluster. ■ The WLS_OAM1 Managed Server on IDMHOST1 and WLS_OAM2 Managed Server on IDMHOST2 are in a cluster and the Access Manager applications are targeted to the cluster. ■ Oracle Directory Services Manager and Oracle Directory Integration Platform are bound to the listen addresses of the WLS_ODS1 and WLS_ODS2 Managed Servers. By default, the listen address for these Managed Servers is set to IDMHOST1 and IDMHOST2 respectively. ■ In the OAM + OIM topology, the WLS_OIM1 Managed Server on OIMHOST1 and WLS_OIM2 Managed Server on OIMHOST2 are in a cluster and the Oracle Identity Manager applications are targeted to the cluster. ■ In the OAM + OIM topology, the WLS_SOA1 Managed Server on OIMHOST1 and WLS_SOA2 Managed Server on OIMHOST2 are in a cluster and the Oracle SOA applications are targeted to the cluster ■ In the OAAM topology, the WLS_OAAM1 Managed Server on OAAMHOST1 and WLS_OAAM2 Managed Server on OAAMHOST2 are in a cluster and the Oracle Adaptive Access server applications are targeted to the cluster. ■ In the OAAM topology, the WLS_OAAM_ADMIN1 Managed Server on OAAMHOST1 and WLS_OAAM_ADMIN2 Managed Server on OAAMHOST2 are in a cluster and the Oracle Adaptive Access Administration console applications are targeted to the cluster. ■ The WLS_OIF1 Managed Server on OIFHOST1 and WLS_OIF2 Managed Server on OIFHOST2 are in a cluster and the Oracle Identity Federation applications are targeted to the cluster.
