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 Creation wizard. The Profile Creation wizard creates
runtime environments for application server processes.
Procedure
- Diagrams: Review the installation
scenarios for the WebSphere Application Server Network Deployment product, as described in Planning to install Network Deployment
.
- Diagrams: Review the installation
scenarios for the Web server plug-ins for WebSphere Application Server, as
described in Planning to install Web server plug-ins
.
- Diagram: Review the installation
scenarios for the Application Client, as described in Planning to install WebSphere Application Client
.
- Diagrams: Review the installation
scenarios for profile creation, as described in Planning to create application server environments
.
- Optional: Review interoperability
and coexistence diagrams to know what is possible with Version 6.x.
WebSphere Application Server Version 6.x 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 following
topics for more information:
- Interoperating
- Setting up Version 4.0.x and Version 6.0.x coexistence
- Setting up Version 5.x and Version 6.0.x coexistence
- Setting up Version 6.0.x coexistence
- Optional: Consider
performance when designing your network, as described in Example: Choosing a topology for better performance
and Queuing network
.
Results
Following this procedure results in reviewing installation scenarios
to identify specific steps to follow when installing more than one component.
