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 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.
- Interoperating
- Coexisting
- 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.
