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 source database. This converts the database from a refreshable clone to a regular database. Following the disconnect operation you are allowed to reconnect the disconnected database to the source database. The reconnect operation is limited to a 24 hour period.

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

Perform the following prerequisite steps as necessary:

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

• From the Oracle Cloud Infrastructure left navigation menu click Oracle AI Database and then click Autonomous AI Database.

• On the Autonomous AI Database page, select your Autonomous AI Database from the links under the Display name column.

Starting from the Source Database Console Disconnect a refreshable clone from the source database and convert the refreshable clone to a read/write database:

1. On the Autonomous AI Database Details page select the Refreshable clones tab.

   This shows the list of refreshable clones.

2. In the row for the refreshable clone you want to disconnect, click at the end of the row and select Disconnect clone from source database.

3. In the Disconnect refreshable clone dialog enter the source database name to confirm disconnecting the clone.

4. Click Disconnect refreshable clone.

Starting from the Clone Database Console Disconnect a refreshable clone from the source database and convert the refreshable clone to a read/write database:

1. On the Autonomous AI Database Details page, under Clone information, in the Clone source field click click at the end of the row and select Disconnect.

2. In the Disconnect refreshable clone dialog enter the source database name to confirm disconnecting the clone.

3. Click Disconnect refreshable clone.

The Autonomous AI Database Lifecycle state of the cloned database changes to Updating. When the disconnect operation completes the Lifecycle state changes to Available and the Mode shows Read/Write.

After you disconnect a refreshable clone, the Oracle Cloud Infrastructure Console updates with the following changes:

• The Display name on the Autonomous AI Databases page updates and does not show the Refreshable clone indicator for the cloned instance.

• On the disconnected instance, the Autonomous AI Database Details page updates and does not show the Refreshable clone indicator, and the Clone information area is removed.

• On the disconnected instance the Autonomous AI Database details page displays a banner indicating the date and time up to which you can reconnect the database to the source. The banner also includes a Reconnect refreshable clone link. For example:

  See Reconnect a Refreshable Clone to the Source Database for more information.

• On the source database, on the Autonomous AI Database Details page, when you select the Refreshable clones tab, the list of refreshable clones no longer shows an entry for the disconnected clone.

Notes for disconnecting a refreshable clone.

• 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.

• After you disconnect a refreshable clone you have 24 hours to reconnect. After the reconnect period is over, the reconnect operation is not available. If you do not reconnect a disconnected refreshable clone, the clone is a standard Autonomous AI Database and there is no longer an option to reconnect the database to the source database.

• A disconnected refreshable clone is no longer associated with the source database. To use the database or to initiate the reconnect operation, you must know the name of the refreshable clone database that was disconnected from the source database. You must initiate the reconnect operation from the disconnected clone database. You cannot reconnect a disconnected clone from the source database.

Note: You can also use the Autonomous AI Database API to disconnect refreshable clone using UpdateAutonomousDatabase. See for more information.UpdateAutonomousDatabase
