2.2 About ULN

The repositories available on the Oracle Linux yum server are aligned with the channels that are available on the Unbreakable Linux Network (ULN), with the exception of ULN channels that are limited to Oracle Linux Premier Support customers. These include channels for products such as Ksplice and DTrace.

ULN is tightly integrated with yum. If you have registered your system with ULN, you can use yum commands with ULN channels to maintain the software on your system, as described in Oracle® Linux: Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7.
