Introduction to tuning the WebSphere Application Server cluster with caching
The purpose of this project was to analyze parameter and configuration variations to identify what influences the throughput when caching is enabled in a WebSphere® Application Server 6.1 cluster running the Trade workload in a secure environment.
Objectives
An earlier project showed that when a single WebSphere Application Server 6.0.2 uses caching, it provides a significant throughput improvement. The first experience with a WebSphere cluster showed that caching in the cluster is much more complex, where overhead can easily increase in a way that negates any advantage gained with caching.
