This topic describes common installation scenarios and
links to component installation procedures for each scenario.
Before you begin
IBM WebSphere Application Server is an integrated platform
that contains an application server, a set of Web development tools,
a Web server, and additional supporting software and documentation.
The
following information describes scenarios for installing the product
in various topologies on one or more machines:
About this task
Each scenario includes a diagram and a list of detailed
installation steps.
Procedure
- Single-machine installation of WebSphere Application
Server
Installing WebSphere Application Server by itself
on a single machine creates a stand-alone application server, which
is automatically named server1. Installing the base product creates
the core product files and a profile for application
server. The profile is a separate set of files that define the application
server environment.
In this scenario, the application server
uses its internal HTTP transport chain for communication instead of
a using a separate web server (on a separate machine) to possibly
offload some processing.

- Install WebSphere Application Server.
- Single-machine installation of WebSphere
application servers and a Web server
Installing a Web
server, such as IBM HTTP Server, on the same machine as the application
server provides more configuration options. Installing a Web server
plug-in enables the Web server to communicate with the application
server. However, this scenario is not a typical production environment.
When everything is on one machine, neither the web server or the
application server will run as fast as if they were on separate machines
because they are both competing for the same CPU resources.

- Install WebSphere Application Server.
- Install WebSphere Application
Server.
- Install IBM HTTP Server or another
supported Web server.
- Install the Web server plug-ins
and configure the Web server using the Plug-ins installation wizard.
Results
Following this procedure results in reviewing common installation
scenarios to find a possible match for the topology that you intend
to install. Each high-level procedure shows the installation order
for the components that comprise the topology.
What to do next
After determining a possible topology, follow the steps
in the overall procedure.
One step not mentioned in any of these
scenarios is to prepare the operating system for installation. Useful
links to the installation procedures for each installable component
are in the list of related topics.
