About ULN

The Unbreakable Linux Network (ULN) is Oracle's comprehensive service for managing software updates, patches, and channel-based repositories for Oracle Linux systems. To use ULN, you must be an Oracle Linux Support customer.

ULN provides software in organized groups called channels. Each channel contains packages for a particular Oracle Linux version, system architecture, or purpose. Administrators select which channels a system uses to control what software and updates that system can receive.

Using ULN has advantages over yum. ULN contains access to extra software that's not available through the public Oracle Linux yum server. Most notably, ULN provides access to Oracle Ksplice software channels so that you can automatically update the system kernel without requiring a reboot, along with several other channels for commercially available software from Oracle. Therefore, you can download useful packages that aren't included in the original distribution.

ULN offers software patches, updates, and fixes for Oracle Linux, and information about yum, dnf, Ksplice, and support policies. The ULN Alert Notification Tool periodically checks with ULN and alerts you when updates are available.
