Learn about common installation scenarios for a WebSphere® Application Server product.
Before you begin
Determine what components you want to use for your application serving environment. The
installation scenarios can help you to understand the capabilities of your WebSphere Application Server
product. Knowing what you can do with the product might influence how you install the product and
other components.
About this task
The installation scenarios use topology diagrams and descriptions to show what components to
install for a given topology. The scenarios also have installation steps that link to specific
procedures for installing a component, running a command, or using a tool.
Review the scenarios to determine which topology best fits your needs. The diagrams and their
accompanying procedures can serve as a roadmap for installing a similar topology.
Procedure
-
Review the installation scenarios for the WebSphere Application Server Network
Deployment product, as described in Planning to install WebSphere Application Server.
If you might need the ability to quickly switch the service level of one or more
application servers, consider installing the application servers in a way that allows you to swing
profiles. For more information, see Swinging profiles between product installations.
-
Review the installation scenarios for the Web Server Plug-ins for WebSphere Application Server as
described in the article Selecting a web server topology diagram and roadmap.
-
Review the installation scenarios Application Client for IBM WebSphere Application Server as
described in Planning to install the Application Client for IBM WebSphere Application Server.
- Optional:
Review interoperability and coexistence scenarios to know what is possible with the current
version.
WebSphere
Application Server 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, running on separate machines.
Coexistence describes multiple versions or instances running on the same machine
at the same time.
Interoperability support enhances migration scenarios with more configuration options.
Interoperating is often more convenient or practical during the migration of a configuration from an
earlier WebSphere Application Server version to a later one. Some machines can have the earlier
product version and other machines can have the later version. An environment of machines and
application components at different software version levels can involve both interoperability and
coexistence.
It is often impractical, or even physically impossible, to migrate all of 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. See the migration
documentation for more information.
- Optional:
Consider performance when designing your network as described in the documentation for the performance topologies and Queuing network.
Results
Following this procedure results in reviewing installation scenarios to identify specific
steps to follow when installing more than one component.
What to do next
After determining an appropriate installation scenario, install the necessary components
and configure the products for the system that you selected.
