Add CPU or Storage Resources or Enable Auto Scaling

Describes how to scale your Autonomous Database on demand by adding CPU cores or storage. Also describes how to enable auto scaling.

Perform the following prerequisite steps as necessary:

  • Open the Oracle Cloud Infrastructure Console by clicking the navigation icon next to Oracle Cloud.

  • From the Oracle Cloud Infrastructure left navigation menu click Oracle Database and then, depending on your workload click one of: Autonomous Data Warehouse, Autonomous JSON Database, or Autonomous Transaction Processing.
  • On the Autonomous Databases page select an Autonomous Database from the links under the Display Name column.

  1. On the Details page, click Manage Scaling.
  2. In the Manage scaling area, add resources for your scale request.
    • Enter a value or click the up arrow to select a value for OCPU count. The default is no change.
    • Enter a value or click the up arrow to select a value for Storage (TB). The default is no change.
  3. To enable OCPU auto scaling, select OCPU auto scaling.

    Select OCPU auto scaling to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand, compared to the database operating with OCPU auto scaling disabled. The additional resources are available until you disable OCPU auto scaling by deselecting OCPU auto scaling.

    If OCPU auto scaling is disabled while more CPUs are in use than the specified OCPU count, then Autonomous Database scales the number of OCPU cores in use down to the OCPU count number.

    See Use Auto Scaling for more information.

  4. To enable Storage auto scaling, select Storage auto scaling.

    When you select Storage auto scaling the database can expand to use up to three times the reserved base storage.

    If you disable Storage auto scaling and the used storage is greater than the reserved base storage, as specified by the storage shown in the Storage field on the Oracle Cloud Infrastructure Console, Autonomous Database shows a warning on the disable storage auto scaling confirmation dialog. The warning lets you know that the reserved base storage value will be increased to the nearest TB greater than the actual storage usage, and shows the new reserved base storage value.

    See Use Auto Scaling for more information.


    Clicking Shrink initiates the Shrink storage operation. See Shrink Storage for more information.
  5. Click Apply to change your resources.

When you click Apply with a resource change, the Lifecycle State changes to Scaling in Progress.... After the Lifecycle State changes to Available the changes apply immediately.
