  3. Basic WebSphere Application Server V5.0 and V5.1 wsadmin Programmers Guide

    Examples for the WebSphere® Application Server V5.0 wsadmin tool are included in the information center, Redbooks and technotes. Many clients want to advance their skills, doing more than making minor modifications to these examples. A common goal for clients is to use wsadmin to create commands that duplicate the functionality of the administrative console.

    The building blocks in this document help you build the skills necessary to correctly formulate commands that administer a WebSphere Application Server V5.x environment. This document explains how simple techniques that use wsadmin commands, and other available documentation, can help you reach your administrative design goals.

  5. WebSphere tuning for the impatient: How to get 80% of the performance improvement with 20% of the effort

    This article shows you how to tune WebSphere Application Server V6 to get maximum performance improvement with minimal effort. It focuses on command-line tuning with wsadmin and Jython, instead of GUI techniques. By applying rules of thumb for some key parameters, WebSphere Application Server will be able to make optimal use of available hardware resources available with minimal administrative effort. Techniques described here are applicable to any performance tuning problem -- only the implementation of the specific rules of thumb are WebSphere-specific.
