Monitor and tune WebSphere Application Server for WebSphere Commerce

In general, WebSphere Commerce follows the funnelling methodology of tuning most WebSphere applications.

More processing is required on a Web site's front-end servers than on its back-end. Hence, a higher number of requests-serving threads is required at tier one (usually the Web server tier), and is then reduced for each subsequent tier (application server tier and database server tier). This configuration creates a funnel effect in which thread requirements are reduced at each tier.

This chapter introduces some key tuning parameters in WebSphere Application Server, and recommendations from WebSphere Commerce on how to use these parameters. Settings and values configured for some parameters are unique to WebSphere Commerce.
