Before you start
Learn what to expect from this tutorial and how to get the most out of it.
Application servers are a central component of the Web architectures used in enterprise computing today. This tutorial begins with a general discussion of middleware in today's Web architectures, focusing on IBM's WebSphere family of products and the different ways in which WebSphere Application Server can be deployed. The remainder of the tutorial provides detailed information about how to install and configure WebSphere Application Server, integrate it into your system's startup process, and integrate it into your enterprise computing infrastructure. After completing this tutorial, you will understand how to install, configure, and deploy WebSphere Application Server and its relationship with other applications and servers in a Web-based computing environment.
This tutorial provides:
- A review of common Web architectures and the role of application servers and middleware in today's enterprise Web architectures.
- A basic understanding of WebSphere Application Server.
- An overview and comparison of common WebSphere installation and deployment mechanisms.
- Instructions for installing WebSphere Application Server on UNIX and Linux distributions.
- A basic overview of the initial configuration of the WebSphere Application Server.
- Details on how to integrate WebSphere Application Server into the system startup and shutdown processes and how to start and stop the server manually.
This tutorial is written for beginning to intermediate-level systems administrators who may never have installed or configured a Web application server and who may be unfamiliar with modern Web server architectures. To complete the examples in this tutorial, you should have a general familiarity with UNIX command-line shells and text editors.
To run the examples in this tutorial, you need administrative (root) privileges on a UNIX or Linux system on which no application server is currently installed. The system should have a minimum of 1GB of RAM.
When installing WebSphere Application Server, at least 3.1GB of disk space must be available on the system: A minimum of 1.3GB must be permanently available in the file system that contains the /opt directory, and 1.75GB more must be temporarily available in the file system from which you install WebSphere Application Server.
If you are installing WebSphere Application Server on a Linux system, not all Linux distributions include a version of the Java™ Runtime Environment (JRE) that is suitable for use by the installer and certain WebSphere Application Server functions. On unsupported Linux distributions such as Ubuntu, you should download and install the IBM Java software development kit (SDK) and make some minor modifications to your system before installing WebSphere Application Server. See Setting up unsupported Linux distributions for instructions.
If you choose to install the IBM Java SDK, at least 450MB of additional disk space must be available on the system: A minimum of 175MB must be permanently available in the file system that contains the /opt directory, and 275MB more must be temporarily available in the file system from which you install IBM Java SDK.
