2 Configure Your Environment for Patching

To be able to patch an Oracle Private Cloud Appliance with RPM packages released through the Unbreakable Linux Network (ULN), you must set up a ULN mirror in your data center and configure the appliance to use it as a source of updates. Both the Private Cloud Appliance and the ULN mirror must be registered with ULN under your Customer Support Identifier (CSI). One mirror can be used by multiple Private Cloud Appliance systems.

This chapter contains references to CSI administration, ULN registration, and ULN mirror setup, which are described in detail in the Oracle Linux documentation.

• Managing Software in Oracle Linux, a guide applicable to Oracle Linux 8 and Oracle Linux 9

• Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7

To set up a ULN mirror for Private Cloud Appliance patching, you can use Oracle Linux 8 or Oracle Linux 7. The setup differences between these versions are covered in this chapter. However, as Oracle Linux 7 enters extended support in December 2024, we recommend that new ULN mirrors be set up on Oracle Linux 8.
