Use load balancing for distributing service requests from
Rational ClearQuest Web clients across multiple WebSphere Application
Server instances that are running ClearQuest Web server.
Important: WebSphere Application Server supports two
types of load-balanced configurations: horizontal clustering and vertical
clustering. A horizontal cluster comprises two or more physical computers.
In contrast, a vertical cluster has cluster members on the same physical
computer. Rational ClearQuest Web supports only horizontal clustering.
In a WebSphere Application Server horizontal cluster configuration
of ClearQuest Web, ClearQuest Web requests are distributed across
all the load-balanced servers in the deployment. For more information
about horizontal clustering, see the WebSphere Application Server Information
Center (
V8.0,
V8.5).
For information about configuring simple load balancing by using
a web server plug-in configuration file, see the following IBM WebSphere
Application Server Information Center help topics:

server profiles (V8.0, V8.5)

server profiles with an administrative agent (V8.0, V8.5)

server profiles with an administrative agent by using a job manager
