On April 23, 2025, OS Management reaches end of life (EOL). Effective now, the service is no longer available to you in regions where you are not already using OS Management, or to new users with new tenancies. Before the EOL date, we recommend that you migrate your managed instances to the OS Management Hub service. If you are an Oracle Autonomous Linux user, see Important Maintenance Event. For more information, see the Service Change Announcement.
