Many Oracle components have dependencies—that is, one component requires one or more other components. The Oracle installer handles these dependencies automatically, so you can be assured that all required components will be installed. For example, if you choose to install the Oracle Server, the appropriate Required Support Files (RSF) will be recognized as a dependency and will be included automatically in your installation. At the end of the installation, you will see a list of installed components. Don’t be surprised to see components listed there that you did not explicitly request—they are the result of dependency checking.
