WebSphere Application Server 7.0 Administration Guide

By: Steve Robinson

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.

Inside the Application Server


Before we look at deploying an application, we will quickly run over the internals of WebSphere Application Server ( WAS). The anatomy of WebSphere Application Server is quite detailed, so for now, we will briefly explain the important parts of WebSphere Application Server, discovering more about the working internals as we work through each of the remaining chapters.

The figure below shows the basic architecture model for a WebSphere Application Server JVM. There are many more components which we will cover in later chapters.

An important thing to remember is that the WebSphere product code base is the same for all operating-systems (platforms). The Java applications that are deployed are written once and can be deployed to all versions of a given WebSphere release without any code changes.

JVM

All WebSphere Application Servers are essentially Java Virtual Machines (JVMs). IBM has implemented the J2EE application server model in a way which maximises the J2EE...
