Learn about hardware and software requirements, the available WebSphere® Application Server product offerings, and IBM Installation
Manager.
About this task
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.
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
-
To learn about IBM Installation Manager, see Installation Manager overview.
Installation Manager is a single installation program that can use remote or local software
flat-file repositories to install, modify, or update new WebSphere Application Server products. It determines and shows available
packages, including products, fix packs, and interim fixes; checks prerequisites and inter
dependencies; and installs the selected packages. You also use Installation Manager to easily
uninstall the packages that it installed.
IBM Installation Manager Version 1.8.5 or
later is required to install the product.
-
Create an implementation plan for installing WebSphere Application Server for z/OS as described in Creating implementation plans on z/OS.
- Optional:
Review interoperability and coexistence scenarios to know what is possible with the current
version.
WebSphere Application Server can inter-operate 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.
What to do next
Prepare the operating system for product installation. For more information, see
