This illustration shows a sample Oracle Internet Directory configuration on a hardware cluster. It has four components:

• LDAP clients

• Physical Node 1, which has failed

• Physical Node 2 containing Directory Server Instance 1, Logical Host 1, Directory Server Instance 2, and Logical Host 2

• A Shared Disk, which contains Database 1 and Database 2

The LDAP clients connect to both Physical Node 1 and Physical Node 2.

On Physical Node 1, Directory Server Instance 1 runs on Logical Host 1, and it connects with Database 1. On Physical Node 2, Directory Server Instance 2 runs on Logical Host 2, and it connects with Database 2.

A dotted line connects Directory Server Instance 1 and Directory Server Instance 2, indicating that they are in a replication agreement.
