Disconnect a Refreshable Clone from the Source Database

Shows you the steps to disconnect a refreshable clone from the source database. When you disconnect a refreshable clone the refreshable clone is disassociated from the database that was the source database. This is a one time operation, is irreversible, and converts the database from a refreshable clone to a regular database.

There are several ways to find refreshable clones. See View Refreshable Clones for an Autonomous Database Instance for more information.

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 your Autonomous Database from the links under the Display Name column.

Disconnect a refreshable clone from the source database and convert the refreshable clone to a read/write database as follows:

  1. On the Details page, from the More Actions drop-down list, select Disconnect Clone from Source.

    This shows the Disconnect Refreshable Clone dialog.

  2. In the Disconnect Refreshable Clone dialog, enter the source database name to confirm.
  3. Click Disconnect Refreshable Clone.

The Autonomous Database Lifecycle State changes to Updating. When the disconnect operation completes, the Lifecycle State changes to Available and the Mode shows Read/Write.

Notes for disconnecting from the source:

  • After a refreshable clone is disconnected from the source, the Autonomous Database Information area updates and does not show the Refreshable Clone information.

  • Disconnecting a refreshable clone from the source may fail if the source database has scaled down its storage and the refreshable clone has a larger amount of data than the source. In this case, you have the following options:

    • You may scale up the storage on the source database temporarily before disconnecting, and then scale the source back down after disconnecting.

    • Refresh the clone to a point where the scale down of storage occurred.
