4 OS Patch Installation

This chapter illustrates the process of installing an Oracle SD-WAN Edge OS Patch on an Oracle SD-WAN Appliance with OS 4.6 on its active OS partition, but the steps described apply to all patch installations, regardless of OS version.

Oracle SD-WAN Edge OS Patches are uploaded and installed directly to the active OS partition. They are versioned, with each new patch building on the previous version. For this reason, OS Patches cannot be explicitly downgraded; however, if the active and backup OS partitions are switched after a patch has been installed on the active OS partition, the patch is preserved but no longer active.

Note:

Oracle SD-WAN Edge OS Patches can only be installed on top of OS 4.1 and later versions.

Note:

An OS Patch can only be installed on top of its specified base version (e.g., OS Patch 4.6P1 can only be installed on top of OS 4.6).

Procedure Overview

This is an overview of the procedure that is detailed in the following section.

  1. Upload and install the Oracle SD-WAN Edge OS Patch from your local workstation to Oracle SD-WAN Edge. This will install the patch to the active OS partition.
  2. If prompted to do so, reboot the Oracle SD-WAN Appliance in order to activate the patch. This is only required for patches that update critical system libraries.
  3. After installation is complete, verify that the OS Partition version is correct (e.g., 4.6P1) and that any previously established Conduits are still up.

Procedure Details - Network Upload

Follow this procedure if you are able to connect to the Oracle SD-WAN Appliance from your local workstation across a network connection.

  1. Download the OS version you want to patch (e.g., OS 4.6).
  2. Click the link for the patch you are interested in to download the OS Patch file (e.g., talari-os-patch-4.6P1.tar.gz).

    Note:

    Unlike OS Partition Images, patches are not tied to specific Oracle Talari Appliance models.
  3. Log into the appliance web console and locate the OS Patch Network Upload section under Manage Appliance → OS Partitions. If no patches have been previously installed, the base OS version (e.g., 4.6P0) is displayed as the Currently Installed Patch Level.

  7. Wait for installation to complete. You will then be returned automatically to Manage Appliance → OS Partitions, where the patch version (e.g., 4.6P1) will now be displayed as the active version in the OS Partition Versions section.

    Note:

    If prompted to do so, reboot the Oracle SD-WAN Appliance in order to activate the patch. This is only required for patches that update critical system libraries and should be scheduled during a maintenance window.
  8. After installation is complete, verify on the appliance home page that the OS Partition version is correct (e.g., 4.6P1) and that any previously established Conduits are still up.
