Shows you the steps to create an Autonomous Database refreshable clone from the Oracle Cloud Infrastructure Console.

1. On the Details page, from the More actions drop-down list, select Create clone.
2. On the Create Autonomous Database clone page, choose the clone type Refreshable clone from the choices:
   • Full clone: creates a new database with the source database’s data and metadata.
   • Refreshable clone To create a refreshable clone, select this clone type.
   • Metadata clone: creates a new database with the source database’s metadata without the data.
3. Provide basic information for the Autonomous Database clone.

   • Choose your preferred region. Use the current region or select a different region. When you create a refreshable clone, the preferred region list only shows a remote region if your tenancy is subscribed to the remote region (you must be subscribed to the remote region where you create a refreshable clone).

     The list of available regions only shows a remote region if your tenancy is subscribed to the remote region (you must be subscribed to the paired remote region for the target region where you are cloning your database). See Autonomous Database Cross-Region Paired Regions for more information.

   • Create in compartment. See Compartments for information on using and managing compartments.

   • Source database name This field is read-only and shows the name of the source database.

   • Display name Specify a user-friendly description or other information that helps you easily identify the database.

     You can use the name provided, of the form: Clone-of-DBname or change this to the name you want to use to identify the database. The supplied DBname is the name of the source database that you are cloning.

   • Database name: Specify the database name; it must consist of letters and numbers only. The maximum length is 30 characters. The same database name cannot be used for multiple Autonomous Databases in the same tenancy in the same region.

     The default database name is a generated 16-character string.

4. Configure the database (with ECPU compute model)

   • Choose database version: Select the database version. The available database versions are Oracle Database 23ai and Oracle Database 19c.

     Notes for selecting a database version:

     • If the source database version is Oracle Database 23ai, you can select Oracle Database 23ai for the clone.

     • If the source database version is Oracle Database 19c, in regions where Oracle Database 23ai is available, you can choose either Oracle Database 19c or Oracle Database 23ai for the clone.

     • Autonomous Database with Oracle Database 23ai in the Paid tier is available in all commercial public cloud regions except the following regions: Colombia Central: Bogota (BOG), Saudi Arabia Central: Riyadh (RUH), Singapore West: Singapore (XSP), and Spain Central: Madrid (MAD).

   • ECPU count: Specify the number of ECPUs for your database. The minimum value for the number of ECPUs is 2.

   • Compute auto scaling: By default compute auto scaling is enabled to allow the system to automatically use up to three times more CPU and IO resources to meet workload demand. If you do not want to use compute auto scaling then deselect this option.

     See Use Auto Scaling for more information.

   • Show advanced options: Click to show the compute model options or if you want to create or join an elastic pool:

     • Enable elastic pool:

       See Create an Elastic Pool While Provisioning or Cloning an Instance for more information.

     • Compute model: Shows the selected compute model.

       See Compute Models in Autonomous Database for more information.

     • Bring your own license: If you want to Bring Your Own License to the database, click Enable to show the Update license and Oracle Database Edition page.

       See Choose Bring Your Own License Option While Provisioning or Cloning for more information.

   Note
   
   The storage for a refreshable clone is set to the same size as on the source database. To change the storage size for a refreshable clone, you must change the storage value on the source database.
5. Select Enable automatic refresh to specify that the refreshable clone automatically refreshes. By default, Enable automatic refresh is deselected and you must manually refresh at least once every 7 days. When you select Enable automatic refresh, the dialog shows two fields:
   • Frequency of refresh: specifies the refresh frequency in hours or days. The minimum is one hour and the maximum is 7 days. The default Frequency of refresh value is 1 hour.
   • Data lag: specifies the data lag in minutes, hours, or days, the minimum is 0 minutes and the maximum is 7 days. This is the value that specifies the amount of time behind the source that the data refresh is, where a value of 0 specifies that the refreshable clone refreshes to the latest available timestamp. The default Data lag value is 0.
6. Choose network access
   Note
   
   After you clone your Autonomous Database you can change the network access option you select for the cloned instance.

   • Secure access from everywhere

     By default all secure connections are allowed from everywhere.

   • Secure access from allowed IPs and VCNs only

     This option restricts connections to the database according to the access control rules (ACLs) you specify. To add multiple ACLs for the Autonomous Database, select this option and click Add access control rule.

     See Configure Access Control Lists When You Provision or Clone an Instance for more information.

   • Private endpoint access only

     This option assigns a private endpoint, private IP, and hostname to your database. Specifying this option allows traffic only from the VCN you specify; access to the database from all public IPs or VCNs is blocked. This allows you to define security rules, ingress/egress, at the Network Security Group (NSG) level and to control traffic to your Autonomous Database.

     See Configure Private Endpoints When You Provision or Clone an Instance for more information.

7. (Optional) Provide contacts for operational notifications and announcements

   Click Add contact and in the Contact email field, enter a valid email address. If the database you are cloning has a customer contact list, the list is copied. To enter multiple Contact email addresses, repeat the process to add up to 10 customer contact emails.

   See View and Manage Customer Contacts for Operational Issues and Announcements for more information.

8. (Optional) Click Show advanced options to select advanced options.
   • Encryption key

     A refreshable clone uses the encryption key of the source Autonomous Database.

     See Use Customer-Managed Encryption Keys on Autonomous Database for more information.

   • Maintenance

     Patch level By default the patch level is the patch level of the source database. Select Early to configure the instance with the early patch level. Select Regular to configure the instance with the regular patch level.

     See Set the Patch Level for more information.

   • Management

     Shows the character set and national character set for your database.

     See Choose a Character Set for Autonomous Database for more information.

   • Tools

     Refreshable clones inherit their tool status for each built-in tool from the refreshable clone's source database. If the source of a refreshable clone changes its tool configuration, the change is reflected in the refreshable clone after the next refresh.

     See Configure Autonomous Database Built-in Tools for more information.

   • Tags

     If you want to use Tags, enter the Tag key and Value. Tagging is a metadata system that allows you to organize and track resources within your tenancy. Tags are composed of keys and values which can be attached to resources.

     See Tagging Overview for more information.

9. Click Create Autonomous Database clone.

On the Oracle Cloud Infrastructure console the State shows Provisioning... until the refreshable clone is available.

After the provisioning completes the Lifecycle state shows Available and the Mode is Read-only.

After you download the wallet for the refreshable clone and connect to the database, you can begin using the database to perform read-only operations such as running queries or building reports and notebooks.

When automatic refresh is disabled, after you create a refreshable clone, the Oracle Cloud Infrastructure console shows a banner similar to the following with a message indicating the date prior to which the next refresh must be completed (the banner shows the 7 day refresh limit).

See Refresh a Refreshable Clone on Autonomous Database for details on refreshing a refreshable clone.
