The architecture required to use Rational ClearQuest Web with WebSphere Application Server consists of two components:
In a simple configuration, all components of the WebSphere environment and the Rational ClearQuest Server are installed on a single computer that has configured a connection to a ClearQuest database.
To improve performance, you can run the Rational ClearQuest Server on one or more computers that are different from the one that runs the WebSphere environment.
You can deploy the HTTP Server on a computer that is separate from the WebSphere Application Server and add additional Rational ClearQuest server computers to provide more capacity for improving performance, balancing loads, and providing failover service. For more information about multiple-server configurations, see the help for and the Administrator’s Guide for Rational ClearQuest Web .
