Before installing the software, Oracle Universal Installer (OUI) performs several automated checks to ensure that your computer fulfills the basic hardware and software requirements for an Oracle Database installation. If your computer does not meet a requirement, then an error message is displayed. The requirements may vary depending upon the type of computer and operating system you are using, but some prerequisites include:
Sufficient paging space is available.
The appropriate service packs or patches for your operating system are installed.
An appropriate file system format is being used.
