This figure shows the relationship between an original and a replicated Identity Management Infrastructure and Metadata Repository.

A middle-tier instance points to the master host, Host 1. An Oracle Identity Federation instance also points to the master host, Host1. The master host has a master repository that contains a Single Sign-On schema and an Oracle Internet Directory (OID) Schema. The Single Sign-On Server accesses the Single Sign-On schema and communicates with the OID Server. The OID Server accesses the OID schema. The master host also contains Oracle Delegated Administration Services (DAS) and Oracle Directory Integration Platform (DIP) instances.

The Oracle Internet Directory server communicates with the replica host, Host 2, through LDAP-based replication. The replica host contains copies of all of the components of the master host.
