1 Introduction to Unbreakable Linux Network (ULN)

This chapter introduces the Unbreakable Linux Network (ULN), Oracle's service for delivering Oracle Linux software updates, security patches, and extra packages through logically organized channels. It also explains how ULN fits alongside other Oracle Linux software distribution options, and highlights key differences between yum repositories and ULN channels to help administrators get started with software management in enterprise environments.

Important:

The General Oracle Linux documentation no longer describes how to subscribe to ULN channels. As a ULN user, you need to understand the Relationship Between Yum Repositories and ULN Channels.
