You do realize that Oracle is an RDBMS and Red Hat Linux is an O/S... don't you?
And Oracle is installed most often on a Windows server.

Oracle Enterprise Linux is an enterprise-class Linux distribution supported by Oracle. According to the project’s web site, “Oracle starts with Red Hat Linux, removes Red Hat trademarks, and then adds Linux bug fixes.” Oracle Enterprise Linux is, and intends to remain, fully compatible with Red Hat Enterprise Linux.
