Installing a Distributed OracleAS Cold Failover Cluster (Infrastructure) Configuration
8-12 Oracle Application Server Installation Guide
Figure 8–2 Distributed OracleAS Cold Failover Cluster (Infrastructure) Configuration
In a distributed OracleAS Cold Failover Cluster (Infrastructure) configuration, you run
the OracleAS Metadata Repository, Oracle Internet Directory, and Oracle Directory
Integration Platform in an active-passive configuration.
However, the OracleAS Single Sign-On and Oracle Delegated Administration Services
components run in an active-active configuration. You have a load balancer to direct
requests to the nodes running these components.
