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.

The ws_ant tool


ws_ant is based on Apache Ant. Ant is an interpreted language which is designed to sequentially run shell-based commands which can extend to use Java classes. If you wish to learn more about Ant, you can read up about it on the Apache web site located at http://ant.apache.org/.

Ant XML-based configuration files contain sequential commands as groups of tasks. These XML files reference a tree of task groups called targets, in which various tasks are specified to run. Each task is run by an object that implements a particular task interface. WebSphere utilizes Ant and the ws_ant utility provides specific Ant tasks which are designed to make application deployment easier for application developers. It is not recommended that ws_ant be used in production servers as it is strongly linked to development. In enterprise systems, developers will not have access to live systems. ws_ant is not scalable like wsadmin scripting, which is more suitable for enterprise WebSphere designs and...
