Beginning with the Oracle Linux 8 platform images released in October 2021, the OS Management Service Agent plugin is enabled by default in Oracle Cloud Agent 1.16.0 for Oracle Linux 8 instances.

For Oracle Linux 8 instances that were launched before October 2021 (running Oracle Cloud Agent 1.15.0 or earlier), the OS Management Service Agent plugin is disabled by default. The OS Management Service Agent plugin for disabled Oracle Linux 8 instances remain disabled after being updated to Oracle Cloud Agent 1.16.0.

For more information, see Getting Started with OS Management.

OS Management Service Agent Plugin Enabled by Default in September Oracle Linux 7 (aarch64) Platform Image

The OS Management service supports Arm-based shapes beginning with Oracle Cloud Agent 1.15.0 and the OS Management Service Agent plugin is enabled by default in the September Oracle Linux 7 (aarch64) platform image.

For more information about supported images, see Supported Images in the OS Management documentation. For more information about Oracle Cloud Agent releases, see Oracle Cloud Agent Versions.

OS Management Software Source Available for Oracle Linux 6 Extended Support

OS Management provides the Oracle Linux 6 ELS (x86_64) software source for Oracle Linux 6 instances that are in Oracle Linux Extended Support. To ensure that existing Oracle Linux 6 instances receive updates during the extended lifecycle period, you need to manually add the Oracle Linux 6 ELS software source to the instance. For more information about adding software sources, see Adding Software Sources in the OS Management documentation.

Updates in OCI Utilities Version 12.6.1

The ocid service behavior change that enabled the service by default in version 0.12.6 has been reverted in version 0.12.6.1; that is, the ocid service is disabled by default. The ocid service can be started using the following command.

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.

1. Install the oraclelinux-els-release-el6 package to add the ELS repositories for your Oracle Linux 6 instance:

   sudo yum install oraclelinux-els-release-el6

2. Verify that the ELS repositories are enabled:

3. Update the yum repositories to install the latest ELS package updates:

   sudo yum install

Note

The ol6_x86_64_userspace_ksplice_ELS repository is optionally available to obtain Ksplice userspace updates.

To enable the optional ol6_x86_64_userspace_ksplice_ELS repository, edit the oraclelinux-els-ol6.repo file and change the enabled= value from 0 to 1.

For example:

[ol6_x86_64_userspace_ksplice_ELS]
name=Ksplice aware userspace packages for Oracle Linux $releasever ELS ($basearch)
baseurl=https://yum$ociregion.oracle.com/repo/OracleLinux/OL6/userspace/ksplice/ELS/x86_64/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

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.

For more information about IPv6 support in Oracle Cloud Networking, see the following technical resources:

• IPv6 on Oracle Cloud Infrastructure (Oracle Cloud Infrastructure Blog)
• Release Note Announcement
• IPv6 Addresses(Oracle Cloud Infrastructure Networking Service Documentation)

Oracle Linux 8 ol8_oci Yum Repository Archived

The ol8_oci repository has been archived and no new packages are released to this repository. All packages from this repository have been migrated to the ol8_oci_included repository.

Yum Update for Oracle Linux 7 and Oracle Linux 8 Instances

The yum configuration has changed in Oracle Cloud Infrastructure for yum mirror endpoints.

Follow these steps to configure your Oracle Linux 7 and Oracle Linux 8 instances to use the updated configuration.

1. 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.

   For example:

   $ curl -H "Authorization:Bearer Oracle" -sfm 25 \
   http://169.254.169.254/opc/v2/instance/ 2>/dev/null | jq -r '.regionInfo.realmKey'
   oc1

2. Install the oci-linux-config package:

   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

3. Invoke the script to complete the transition to the new mirror endpoints:

   /usr/lib/oci-linux-config/oci_yum_configure.sh

4. Verify that the yum configuration has been updated:

   ls /etc/yum.repos.d

   After running the script, you will see repositories with the .bkp and rpmnew.bkp extensions.

   Oracle Linux 7:

   $ ls /etc/yum.repos.d
   ksplice-ol7.repo          oracle-epel-ol7.repo.rpmnew.bkp     oraclelinux-developer-ol7.repo.bkp
