In OracleAS Cluster (Identity Management) configurations, the Oracle Identity 
Management components and the OracleAS Metadata Repository run on separate 
nodes. All the nodes in an OracleAS Cluster (Identity Management) configuration are 
active. Requests from clients, such as middle tiers, are directed to a load balancer, 
which then directs the requests to one of the active nodes. See 

.

These nodes can belong to a hardware cluster, but this is not required.

These configurations are called "OracleAS Cluster (Identity Management)" because the 
OracleAS Single Sign-On and Oracle Delegated Administration Services components 
are clustered. This means that these components are configured identically across 
nodes.

You need an existing OracleAS Metadata Repository before installing an OracleAS 
Cluster (Identity Management) configuration. You can install OracleAS Metadata 
Repository in one of the following methods:

Install OracleAS Metadata Repository in a new database by using the Oracle 
Application Server installer.
