Preface

Oracle Linux: Unbreakable Linux Network User's Guide describes how to manage software on Oracle Linux systems using the Unbreakable Linux Network (ULN). This guide explains how to register systems with ULN, subscribe to software channels, and keep systems current with updates, security patches, and packages that aren't available through the public Oracle Linux yum server. The information in this guide helps administrators maintain secure, reliable, and up-to-date Oracle Linux environments using ULN.
