Determine which redundancy strategy, if any, your solution is using for messaging services.
If your solution uses load-balancing.
If your solution uses clustered messaging services, the Sun Cluster software must be installed, configured, and verified before Messaging Server.
Use the Java ES installer to install Messaging Server on all computers systems specified in your deployment architecture. The installer does not configure instances of Messaging Server.
Run the Directory Preparation Tool on the computer that is running Directory Server.
Run the Messaging Server configuration wizard.
When you configure Messaging Server you must specify the Directory Server instance where information about Messaging Server users is stored.
When you configure Messaging Server you supply the name of the LDAP directory branch that will represent the email domain managed by the Messaging Server instance. The Messaging Server configuration wizard adds this branch to the tree.
Start and verify all instances of Messaging Server.
If your solution includes single sign-on, configure Messaging Server for single sign-on, restart Messaging Server, and verify functioning of single sign-on.
If your solution includes Sun Cluster software, install, configure, start, and verify the Sun Cluster Agent for Messaging Server.
If your solution uses load balancing for the Administration Server instances, verify that the load balancer is working properly.
