Functional updates occur every two months. Each functional update has two update windows. Your instance's update window is determined by the instance's shape. Instances with a Development shape receive updates two weeks before instances with a Production shape.
- If your organization created the instance in Oracle Integration 3, the person who created the instance chose the shape during provisioning.
- If your organization upgraded the instance from Oracle Integration Generation 2, an administrator chose the shape while scheduling the upgrade.
In Oracle Integration Generation 2, you chose your update window using tags. Oracle Integration 3 uses only an instance's shape to determine the update window.
