Switch an Exadata DB System to the New Resource Model and APIs

If you have existing Exadata DB systems in Oracle Cloud Infrastructure, you can switch them to the new resource model and APIs.

This does not change to the underlying hardware or shape family of your Exadata Cloud Infrastructure instance. The existing DB system APIs will be deprecated for Exadata by Oracle Cloud Infrastructure for all users following written notification and a transition period allowing you to switch to the new API and Console interfaces. Note that this change will not affect bare metal and virtual machine DB systems. Switching to the new resource model does not impact the DB system's existing Exadata databases or client connections. If you have created automation that uses the existing DB system API, your applications may need to be updated to use the new API.

Note:

No new systems can be provisioned with the old DB system resource model/APIs after May 15th, 2021. Support for the old DB system resource model/APIs on existing systems will end on November 15th, 2021. Oracle recommends that you migrate your Exadata Cloud Infrastructure instances to the new resource model APIs as soon as possible.

Converting to the new resource model does not involve any system downtime. After converting your DB system, you will have two new resources in place of the DB system resource: a cloud Exadata infrastructure resource, and a cloud VM cluster resource.

What to Expect After Switching

• Your new cloud Exadata infrastructure resource and cloud VM cluster are created in the same compartment as the DB system they replace.
• Your new cloud Exadata infrastructure resource and cloud VM cluster use the same networking configuration as the DB system they replace.
• After the switch, you cannot perform operations on the old Exadata DB system resource.
• Switching is permanent, and the change cannot be undone
• X6, X7, X8 and Exadata base systems retain their fixed shapes after the switch, and cannot be expanded.

You have a Exadata DB System that needs to be switched to the new resource Model

1. 
   
2. Open the navigation menu. Under Oracle Database, click Oracle Exadata Database Service on Dedicated Infrastructure.
3. Choose your Compartment.
4. In the list of DB systems, find the Exadata DB system you want to switch to the new resource model, and click its highlighted name to view the system details.
5. Click More Actions, then Switch to New API.
6. In the displayed confirmation page, read the What to expect after switching section. When you are ready to switch to the new resource model and APIs, click Start.

   Note:

   Switching an Exadata DB system to the new resource model and APIs cannot be reversed. If you have automation for your system that utilizes the DB system APIs, you may need to update your applications prior to switching.
