1: Single machine topology

Discussion

In this simplest of topologies, all components are installed on the machine containing the Web server. The Web server routes requests, as appropriate, to the WebSphere Application Server for processing.

A WebSphere administrative server stores administrative configuration data in its administrative database. The administrative database or another database might also hold application data for applications that require a place to store data (such as user session information). The machine contains one or more administrative clients for manipulating configuration data.

Typical use

This configuration is most suitable for development, testing, and intranet environments where performance and security are not critical goals. WebSphere Application Server offers great flexibility in configurations, from including the main components on a single machine to splitting the various components onto different machines according to your business needs. Subsequent articles under Section 7.1.3 present various options.

Instructions

To set up the single-machine configuration, perform the Typical installation. See Section 2 (installation) for detailed instructions pertaining to particular operating system, Web server, and database choices.

More complex sample topologies

WebSphere Application Server offers a variety of ways to configure application servers in your environment. See Section 7.1 for a discussion of how to use the WebSphere Application Server, Advanced Edition in a multimachine environment.  Section 7.1.3 describes a number of topologies for setting up multimachine systems.  Many of these system topologies can be combined to reap the benefits and minimize the disadvantages of each configuration. 

Persisting sessions

Most of the topologies support the use of cloned application servers for workload management (see Section 7.2 for details). In such configurations, plan to persist HTTP sessions in a database. See Section 7.1.6.1 for an overview of this topic and Section 4.4.1.1 for instructions.
