Public Yum Server

Last updated: 9 May, 2011
Introduction

The Oracle public yum server offers a free and convenient way to install packages from the Oracle Linux and 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. Note that errata are not available via this public yum server. To access errata (bug fixes, security fixes and enhancement), you must have a valid support contract to access Unbreakable Linux Network (ULN). For more information, see the FAQ below.

This yum server is offered without support of any kind. If you require support, please consider purchasing Oracle Linux support via the online store, or via your sales representative.
