The installation requirements for WebSphere® ESB vary depending on the operating system. You must prepare your operating system before installing WebSphere ESB.
Preparing the operating system involves such changes as allocating disk space and installing patches to the operating system. IBM® tests products on each operating system platform. Such tests verify whether an operating system change is required for the product to run correctly. Without the required changes the products do not run correctly.
Before preparing your installation environment, review the topics in Planning for WebSphere ESB to determine how to set up your system. Then see the specific instructions for your operating system in this section.
