Managing Autonomous Linux Settings

Manage the settings available for Autonomous Linux for autonomous updates and events.

The following tasks for managing Autonomous Linux settings are covered in this topic:

  • Updating the schedule for daily autonomous updates
  • Setting the topic for event notifications
  • Changing the event collection setting

About Autonomous Updates

The Autonomous Linux service provides automatic daily updates (including zero-downtime Ksplice updates for kernel, OpenSSL, and glibc libraries) to Autonomous Linux instances. These updates are referred to as autonomous updates.

The Autonomous Linux service is responsible for setting the correct Yum and Ksplice channels used for autonomous updates in the instance. The following software sources are required for autonomous updates:
  • ol7_ksplice
  • ol7_latest
  • ol7_oci_included
  • ol7_uekr6
  • ol7_userspace_ksplice
Note

If any of these software sources are removed, the Autonomous Linux service automatically restores them.

When performing autonomous updates, the Autonomous Linux service attempts to automatically remediate update problems and notifies you about what succeeded and what failed using Notifications service topics. The content of notification messages includes:

  • For successes, what was updated and if the service remediated a problem in the scheduled update job.
  • For failures, what updates failed, the associated error messages and signature of the failures, and any information needed to provide to the service team in a customer support ticket.
  • For a mix of successes and failures, the details on what was updated and what was not updated, in addition to the information previously noted.

For more information about managing settings for Autonomous Linux, such as setting the daily update time for autonomous updates or setting up notifications, see Settings Available for Autonomous Linux and Editing Settings for Autonomous Linux.

Settings Available for Autonomous Linux

You can update the following Autonomous Linux settings using the Console, API, or CLI.

Autonomous Updates

This setting allows you to edit the start time for daily autonomous updates.

When you create an Autonomous Linux instance, OS Management creates a controlled scheduled job for daily autonomous updates. The scheduled job appears in the Scheduled Jobs page using the following naming convention: Daily Autonomous Updates for <instance-name>. This scheduled job cannot be deleted or skipped. For information about viewing scheduled jobs, see Managing Scheduled Jobs and Work Requests.

Event Collection

This setting allows you to edit the event diagnostic collection setting. By default, this check box is selected, allowing event diagnostic information to be automatically stored in Oracle Cloud Infrastructure.

For more information about the diagnostic information collected by Autonomous Linux, see About the Information Collected from an Instance.

Notification Topic

This setting allows you to edit the Notifications service topic used to send notifications about autonomous updates and events that occur on Autonomous Linux instance. By default, when you create an Autonomous Linux instance, the instance is not configured to use any topic. To set the topic to use for notifications, see Editing Settings for Autonomous Linux. If you have not created a topic to use for the instance, you are given the option to create a topic in the Console.

For information about creating and subscribing to topics, see Managing Topics and Managing Subscriptions in the Notifications service documentation.
