Autonomous Database provides cloning where you can choose to create a full clone of the active instance, create a metadata clone, or create a refreshable clone. With a refreshable clone the system creates a clone that can be easily updated with changes from the source database.

For details on creating a clone that is a full clone or a metadata clone, see Cloning and Moving an Autonomous Database.

• About Refreshable Clones on Autonomous Database
  When you create a refreshable clone for an Autonomous Database instance the system clones the source database to a database that can be refreshed from the source.
• Prerequisites for Creating a Refreshable Clone
  Describes prerequisites for creating a refreshable clone.
• Create a Refreshable Clone for an Autonomous Database Instance
  Shows you the steps to create an Autonomous Database refreshable clone from the Oracle Cloud Infrastructure Console.
• View Refreshable Clones for an Autonomous Database Instance
  If you know a refreshable clone's display name, you can view the instance by selecting from the list of Autonomous Databases on the Oracle Cloud Infrastructure Console.
• Edit Automatic Refresh Policy for Refreshable Clone
  When you enable the automatic refresh option a refreshable clone automatically refreshes from the source database at regular intervals. By default, automatic refresh is disabled and you must manually refresh at least once every 7 days.
• Refresh a Refreshable Clone on Autonomous Database
  Shows you the steps to refresh a refreshable clone from the Oracle Cloud Infrastructure Console.
• Disconnect a Refreshable Clone from the Source Database
  Shows you the steps to disconnect a refreshable clone from the source database.
• Reconnect a Refreshable Clone to the Source Database
  Shows you the steps to reconnect a disconnected clone to the source database.
• Create a Cross Tenancy or Cross-Region Refreshable Clone
  You can create a refreshable clone in a different tenancy (destination tenancy). When you create a cross tenancy refreshable clone, the refreshable clone in the destination tenancy can be in the same region or in a different region (cross-region).
• Use the API
  Provides details for using the APIs to create, refresh, list, disconnect, and reconnect a refreshable clone.
• Refreshable Clone Notes
  Lists limitations and notes for Autonomous Database refreshable clones.
