General Notices for Oracle Linux Images
Some changes that affect existing Oracle Linux images running on Oracle Cloud Infrastructure are difficult to attach to specific image releases. Typical examples include changes to support status, yum infrastructure, or security-related points of interest. This document tracks notices that apply generally to all Oracle Linux based images. Refer to this document regularly for changes and updates. For release notes pertaining to specific Oracle Linux images, see Image Release Notes.
2021.06 - Refactored Oracle Cloud Infrastructure Utilities
A new version of the
oci-utils package is available with usability enhancements.
Beginning with the

2021.04 - Oracle Linux Extended Support for Oracle Linux 6 Instances
Beginning in April 2021, Oracle Linux 6 moves from Oracle Linux Premier Support to Oracle Linux Extended Support. Oracle Cloud customers receive access to Oracle Linux Extended Support as part of their Oracle Linux Premier support, when running Oracle Linux 6 instances in Oracle Cloud Infrastructure. For more information, see Oracle Linux Extended Support.
During the extended lifecycle period, Oracle Linux 6 images are published quarterly.
Follow these steps to ensure that your Oracle Linux 6 instances receive updates during the extended lifecycle period.

2021.04 - IPv6 Enabled by Default in Oracle Linux 7 Images
Beginning with the Oracle Linux 7 platform images released in April 2021, IPv6 is enabled by default. This change has been implemented in support of the General Availability (GA) launch of IPv6 in Oracle Cloud Networking. IPv6 addressing is now supported for all commercial and government regions. Previously, IPv6 addressing support was available only in government regions.
IPv6 has been enabled by default in Oracle Linux 8 since the initial release of the Oracle Linux 8 platform image in July 2020.
For more information about IPv6 support in Oracle Cloud Networking, see the following technical resources:
2021.04 - Oracle Linux 8 ol8_oci Yum Repository Archived
ol8_oci repository has been archived and no new packages are
released to this repository. All packages from this repository have been migrated to
No action is required for new or existing Oracle Linux 8 instances. The
ol8_oci_included repository is enabled by default.
2021.03 - Yum Update for Oracle Linux 7 and Oracle Linux 8 Instances
The yum configuration has changed in Oracle Cloud Infrastructure for yum mirror endpoints.
No action is required for new Oracle Linux 7 and Oracle Linux 8 instances launched in Oracle Cloud Infrastructure after March 2021, as the changes are automatically applied. Although existing yum configurations continue to work in older instances, it is recommended that you update your instances to the new yum configuration.
Follow these steps to configure your Oracle Linux 7 and Oracle Linux 8 instances to use the updated configuration.
Determine the Oracle Cloud Infrastructure realm where the image is running:
curl -H "Authorization:Bearer Oracle" -sfm 25 http://169.254.169.254/opc/v2/instance/ 2>/dev/null | jq -r '.regionInfo.realmKey'
Notice the realm key displayed in the output. If the output displays a realm key from OC1 to OC4, proceed to the next step.
curl -H "Authorization:Bearer Oracle" -sfm 25 http://169.254.169.254/opc/v2/instance/ 2>/dev/n ull | jq -r '.regionInfo.realmKey' oc1
sudo yum -y install oci-linux-config
During the installation of this package, the following message is displayed:
IMPORTANT: PLEASE NOTE!! Oracle Linux yum repository configurations have been updated. New repository configuration files have been installed but are disabled. To complete the transition, run this script as root user:/usr/lib/oci-linux-config/oci_yum_configure.sh
Invoke the script to complete the transition to the new mirror endpoints:
Verify that the yum configuration has been updated:
After running the script, you will see repositories with the
