Introduction

The Oracle public yum server offers a free and convenient way to install the latest Oracle Linux packages as well as packages from the Oracle VM installation media via a yum client.

You can download the full Oracle Linux and Oracle VM installation media via edelivery.oracle.com/linux. To stay current on errata updates, you may wish to subscribe to the Oracle Linux errata mailing list.
