1 Patching Your Oracle Private Cloud Appliance

This guide describes the patching process for your Oracle Private Cloud Appliance.

Patching is different from upgrading.

Upgrading

Upgrades are delivered as ISO files and performed by using the Upgrader Tool. ISO releases include any patch updates that were delivered prior to the ISO release. For information about upgrading, see Upgrading Oracle Private Cloud Appliance in the Oracle Private Cloud Appliance Administration Guide for Release 2.4.4.

Patching

Patches are available as RPM packages through dedicated channels on the Unbreakable Linux Network (ULN). Patching provides security updates, kernel changes, and bug fixes between larger ISO releases.

This chapter describes two ways to configure ULN access for the Private Cloud Appliance:

• Through a local mirror server in your data center.

• Direct access to ULN without going through a mirror.

To use patching, do the following:

1. Obtain a valid Customer Support Identifier (CSI).

   Access to ULN requires a valid Customer Support Identifier (CSI). Your CSI is an identifier that is issued to you when you purchase Oracle Support for an Oracle product. If you do not already have one, get a valid CSI for Oracle Private Cloud Appliance 2.4.x engineered systems. You must provide a valid CSI that covers the support entitlement for each system that you register with ULN. For more information, see CSI Administration in Oracle Linux Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7.

2. Configure your environment to access channel updates. See Configuring Private Cloud Appliance Direct Access, Registering Your Oracle Private Cloud Appliance for ULN Updates, and Configuring a Mirror Server.
