1 Patching Your Oracle Private Cloud Appliance

This document describes the patching process for your Oracle Private Cloud Appliance. Upgrading your appliance is a different process, refer to the System Upgrade chapter of the Oracle Private Cloud Appliance Administrator Guide for those directions.

Starting with release 3.0.1, Oracle Private Cloud Appliance supports patching updates for security fixes and software errata between major releases. To take advantage of this feature you must configure your environment to support channel updates.

Patches are delivered as RPM packages through a series of dedicated channels on the Unbreakable Linux Network (ULN). To gain access to these channels, you need a Customer Support Identifier (CSI) and a ULN subscription.

Oracle Private Cloud Appliance is not allowed to connect directly to Oracle ULN servers. You must use a ULN mirror on a system inside the data center. The patch channels are then synchronized on the ULN mirror, where the management nodes can access the RPMs. Compute nodes need access to a subset of the RPMs, which are copied to a designated location on the internal shared storage and kept up-to-date.
