About Installation Fixup Scripts
Oracle Universal Installer detects when the minimum requirements for an installation are not met, and creates shell scripts, called fixup scripts, to finish incomplete system configuration steps.
About Operating System Requirements
Depending on the products that you intend to install, verify that you have the required operating system kernel and packages installed.
