This topic describes common product topologies that you can install with the product.
Before you begin
Use this topic to understand the capabilities of your product package. Knowing what you can do with the product might influence how you install the product and other installable components on the product disc.
Why and when to perform this task
This topic describes topology diagrams and shows you how to create the topologies by showing what components to install for each topology.
Phased installation roadmap
You can also use the product CD to install an application client environment on a client machine. Running Java 2 Platform, Enterprise Edition (J2EE) and thin application clients that communicate with WebSphere Application Server requires that elements of the Application Server are installed on the machine on which the client runs. However, if the machine does not have the Application Server installed, you can install Application Server clients to provide a stand-alone client run-time environment for your client applications.
You can use the Rational Web Developer CD in the primary packet of discs to install a fully integrated development environment that includes an exact replica of the Application Server for development testing.
Installation features
Feature | Description |
The Express product includes Application Server nodes. | You can use the Profile creation wizard to create stand-alone application server nodes after installing the Express product. You do not have to reinstall the product to create additional application servers. All application servers on a machine share the same core product files. |
The product CD includes all of the installable components that are required to create an e-business environment. | You can use the product CD to install the IBM HTTP Server, the Web server plug-ins, and the WebSphere Application Server Clients. You do not have to use separate CDs. Separate installation programs exist within component directories on the product CD. |
Each installable component has its own installation program. | You can use the V6 launchpad to install any installable component on the product CD. Or you can install each component directly using the install command in each component directory. |
The launchpad can install any installable product in the primary packet of compact discs. | The launchpad for the Express product can also install the Rational Web Developer on Windows and Linux (Intel) systems. Rational Web Developer is on separate CDs, which requires you to change discs to launch the installation. |
Review topology diagrams for each of the following installable components to determine which topology best fits your needs. The diagrams and their accompanying procedures can serve as a roadmap for installing a similar topology.
In addition to product installation diagrams for the installable components, this topic also links to a roadmap for using the Profile creation wizard, which is new for Version 6. The Profile creation wizard lets you create run-time environments for application server processes.
Each of the following installation scenarios includes topology diagrams and associated installation steps. Each step links to a specific procedure for installing a component or to a description of a command or tool.
Steps for this task
WebSphere Application Server V6 can interoperate with your other e-business systems, including other versions of WebSphere Application Server. Interoperability provides a communication mechanism for WebSphere Application Server nodes that are at different versions. Coexistence describes multiple versions or instances running on the same machine, at the same time.
Interoperability support enhances migration scenarios with more configuration options. It often is convenient or practical to interoperate during the migration of a configuration from an earlier WebSphere Application Server version to a later one when some machines are at the earlier version and some machines are at the later version. The mixed environment of machines and application components at different software version levels requires interoperability and coexistence.
It is often impractical, or even physically impossible, to migrate all the machines and applications within an enterprise at the same time. Understanding multiversion interoperability and coexistence is therefore an essential part of a migration between version levels.

Result
You can review installation scenarios to identify the specific steps to follow when installing more than one component on a single machine or on separate machines.What to do next
After determining an appropriate installation scenario, you are ready to install the necessary components and to configure the products for the system that you selected.Related tasks
