Configuring Heterogeneous Load Balancing 

Use

You can enable your HTTP Provider Service to perform heterogeneous load balancing for client requests to distributed Web applications that run within the J2EE Engine cluster. This function is very useful if you do not want your Web application to be started on all server processes in the cluster.

When you enable heterogeneous load balancing on HTTP Provider Service, you can be sure that client requests to a specific Web application are directed to a server process where the application is available. Subsequent requests to the same application are dispatched to the same server process where the application session has been already established. For more information about the heterogeneous load balancing mechanism used by HTTP Provider Service see Load Balancing for J2EE Web Applications in the Architecture Manual.

Procedure

Use the Visual Administrator tool to enable heterogeneous load balancing:

...

       1.      Open the Properties tab of the HTTP Provider Service on the dispatcher.

       2.      Assign value true to the HeterogeneousLoadBalancing property.

If you set the value false to this property, the HTTP Provider Service will perform homogeneous load balancing based on the J2EE Engine Load Balancing System as described in Load Balancing by the Java Dispatcher in the Architecture Manual.

       3.      Choose Update to add it to the list of properties.

       4.      To apply these changes, choose  (Save Properties).
