Overview

Installation scenarios describe the products to install and the basic installation steps. This topic provides common installation scenarios for a WAS product.

Determine what components you want to use for the Web serving environment. The installation scenarios can help you to understand the capabilities of the WAS 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.

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 appserver processes.

 

Procedure

  1. Review the installation scenarios for the WAS ND product

  2. Review the installation scenarios for the Web server plug-ins for WAS

  3. Review the installation scenarios for the Application Client

  4. Review the installation scenarios for profile creation.

  5. Optional: Review interoperability and coexistence diagrams to know what is possible with V6.x.

    WAS V6.x can interoperate with other e-business systems, including other versions of WAS. Interoperability provides a communication mechanism for WAS 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 WAS 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.

  6. Optional: Consider performance when designing the 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.
