Overview of this book

As an administrator you need a secure, scalable, resilient application infrastructure to support the developers building and managing J2EE applications and Service Oriented Architecture services. WebSphere application server, a product from IBM, is optimized to ease administration and improve runtime performance. It helps you run applications and services in a reliable, secure, and high-performance environment to ensure business opportunities are not lost due to application downtime. It's easy to get started and tame this powerful application server when you've got this book to hand. This administration guide will help you provide an innovative, performance-based foundation to build, run, and manage J2EE applications and SOA services, offering the highest level of reliability, security, and scalability. This book will take you through the different methods for installing WebSphere application server and demonstrate how to configure and prepare WebSphere resources for your application deployments. During configuration you will be shown how to administer your WebSphere server standalone or using the new administrative agent, which provides the ability to administer multiple installations of WebSphere application server using one single administration console. WebSphere security is covered in detail showing the various methods of implanting federated user and group repositories. The facets of data-aware and message-aware applications are explained and demonstrated giving the reader real-world examples of manual and automated deployments. Key administration features and tools are introduced, which will help a WebSphere administrator manage and tune their WebSphere implementation and application for success.

Chapter 7. Monitoring and Tuning

Keeping your WebSphere system well-oiled is paramount in keeping your environment as trouble-free as possible. In a software world, for some strange reason, things break and they stop running. This can be due to software bugs, network traffic, server load, and so on. By tuning your environment, you will ensure your applications perform as best as possible and by monitoring them you will be able to keep an eye on your systems to ensure that they run error-free.

In this chapter, we will cover the following topics:

  • Using Tivoli Performance Viewer ( TPV)

  • Request metrics and PMI

  • Dynamic caching

  • Java Virtual Machine (JVM) parameters

  • Java core dumps

  • Java heap dumps

  • Basic JVM tuning

Before we look at how to tune WebSphere's configuration, we will need to look at some of the tools that are provided within WebSphere itself, which can be used to view runtime metrics and monitor the state of application running within WebSphere Application Server (WAS). We will then discuss some...
