WebSphere Enterprise Service Bus for z/OS, Version 6.2.0 Operating Systems: z/OS


Determining the products to install

The design of your deployment environment includes determining how many and which type of software products you may require. Based on your needs the product requirements may vary among the computer LPAR systems involved in the environment. Not every server in a deployment environment requires a WebSphere® Enterprise Service Bus.

Before you begin

You should have a detailed design that lists:

About this task

After designing your deployment environment and before purchasing your software, use this task to determine the appropriate software needed for your deployment environment.
Procedure
  1. Count the number of unique LPARs that will host the various components of the deployment environment.
    Important: When you are running multiple servers on the same LPAR system, you must install the software that provides the most functionality you need for any server running on that LPAR system.
    This count includes:
    • The number of deployment managers you need. The software running on the managed servers determines what software you install on the deployment manager.
    • WebSphere ESB instances
    • Messaging engines that are not already counted: representing the number of unique WebSphere Application Server instances
  2. Determine whether the cost of the software exceeds the budget for the project.
  3. Optional: Adjust your design to meet your financial requirements. You will need to host multiple servers on the largest capacity LPARs to reduce costs.
    • Create multiple server instances of the same type on higher-capacity LPARs rather than separate instances on separate LPARs so the number of instances remains the same but the software needed decreases.
    • Decide whether you need unique LPARs hosting messaging engines. If not, eliminate them.
    • Remove applications from the design to decrease the number of application server instances required.

Results

You now know the software required to implement the design.

What to do next

Order the software you need.
