Requirements and Sequencing Issues

Messaging Server requires Directory Server, but not necessarily a local copy. In addition, Messaging Server requires a local copy of Administration Server. You will need the Sun Cluster Core component as well as the Sun Cluster Agents for Directory Server, Administration Server, and Messaging Server. If a remote Directory Server is used, then the Sun Cluster Agent for Directory Server is not required.

Installing, configuring, and starting the components in the correct order is crucial for a successful Sun Cluster implementation.

1. Installing the Java ES Sun Cluster component

2. Configuring the Sun Cluster framework

3. Installing the additional Java ES components that are required for Messaging Server to operate in the cluster

4. Configuring the Sun Cluster data services using the agents for the relevant Java ES components

At least two installation sessions are performed on each node in the cluster.
