9.1 OracleAS Cluster (Identity Management): Introduction
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
Figure 9–1 .
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.
Database (OracleAS Metadata Repository) Requirement
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.
