This figure shows two active nodes fronted by an external load balancer. The active nodes run all the Oracle Identity Management components (Oracle Internet Directory, OracleAS Single Sign-On, Oracle Delegated Administration Services, Oracle Directory Integration and Provisioning, OracleAS Certificate Authority, and Oracle HTTP Server). The load balancer is configured with two virtual server names: one for HTTP(S) traffic and one for LDAP(S) traffic. Clients send their requests to the appropriate virtual server name.
