General Notices

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 provides the Oracle Linux 6 ELS (x86_64) software source for Oracle Linux 6 instances that are in Oracle Linux Extended Support. This software source is added to newly created Oracle Linux 6 instances by default. 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.

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.

sudo systemctl enable --now ocid.service

For more information, see the OCI Utilities documentation.

To upgrade from version 0.12.6 to 0.12.6.1:

1. Stop the ocid daemon service.

   sudo systemctl stop ocid.service

2. Disable the ocid daemon service.

   sudo systemctl disable ocid.service

3. Install version 0.12.6-1.

   sudo yum update oci-utils

4. Reboot the instance.

   sudo reboot

The OCI Utilities (oci-utils) package version 0.12.6.1 includes the following updates:

• The oci-iscsi-config attach and oci-iscsi-config create utility commands include a new chap option.
• The options for oci-notify utility have been updated. These updates are backward compatible with other updates.
• OCI utilities no longer require the installation of the python36-oci-cli package.
• The ocid service is enabled by default.

Beginning August 31, 2021, Oracle Autonomous Linux is integrated with OS Management in Oracle Cloud Infrastructure. Before creating Oracle Autonomous Linux instances, see the getting started documentation for information about supported images and required IAM policies. Existing instances that were launched before August 31, 2021 remain standalone instances until a migration plan is available. For more information, see Oracle Autonomous Linux.

A new version of the oci-utils package is available with usability enhancements. Beginning with the 0.12.5 release, the oci-iscsi-config and oci-network-config utilities have been refactored for improved usability.

To update to the latest version of oci-utils:

sudo yum update oci-utils

For more information, see the OCI Utilities documentation. In addition, the following training videos are available with information about these utilities:

• For a training video that demonstrates how to use the oci-network-config utility, see Network Interface Management Using OCI Utilities on Oracle Linux Instances in the Oracle Learning Library.
• For a training video that demonstrates how to use the oci-iscsi-config utility, see Using OCI Utilities for Managing iSCSI Storage for Oracle Cloud Infrastructure Instances in the Oracle Learning Library.

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:

   yum repolist

   For example:

   $ yum repolist
   Loaded plugins: security, ulninfo
   repo id                                               repo name                                                                                           status

   repolist: 38287

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

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)

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.

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
   ksplice-uptrack.repo      oracle-linux-ol7.repo               oraclelinux-developer-ol7.repo.rpmnew.bkp
