Installation scenarios describe the products to install
and the basic installation steps. This topic provides common installation
scenarios for a WebSphere® Application Server product.
Before you begin
Determine what components you want to use for your Web 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.
In addition to product installation
diagrams for the installable components, this topic also links to
a roadmap for using the Profile Management Tool.
The Profile Management Tool creates
runtime environments for application server processes.
Procedure
- Diagrams: Review the installation scenarios for
the WebSphere Application Server product,
as described in Planning to install WebSphere Application Server.
- Diagrams: Review the installation scenarios for
the Web server plug-ins for WebSphere Application Server,
as described in the topic "Selecting a Web server topology diagram
and roadmap".
- Diagram: Review the installation scenarios for the
Application Client, as described in Planning to install WebSphere Application Client.
- Optional: Review interoperability and coexistence
diagrams 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 Queing
network.
Results
Following this procedure results in reviewing installation
scenarios to identify specific steps to follow when installing more
than one component.
