The basic steps for installing and configuring Instant Messaging are the following:
Use the Java ES installer to install Instant Messaging on all computers systems specified in your deployment architecture.
When you install Instant Messaging you satisfy the web container dependency by installing the web container in which Instant Messaging runs or by specifying a wed container already installed on the computer.
If the solution uses Access Manager single sign-on, you satisfy the Access Manager dependency by installing either a copy of the Access Manager SDK or a local copy of Access Manager.
Run the Instant Messaging configuration wizard. When you configure Instant Messaging you must specify the repository for user and group data (typically a Directory Server instance, specified with a URL).
Start and verify all instances of Instant Messaging.
If your solution uses load balancing for the Instant Messaging instances, verify that the load balancer is working properly.
