Autonomous Database Cross-Region Paired Regions
Autonomous Database provides paired regions for creating cross-region databases, including cross-region clones and cross-region disaster recovery peers.
The Region list is shows paired regions when you add a remote disaster recovery peer or when you create a clone in a different region. The Regioin list only shows paired regions. That is, if your tenancy is not subscribed to region that is paired to the source region, then the region is not displayed. To subscribe to a region, see Managing Regions.
If you do not see a region that you are subscribed to in the Region list, open a support ticket to request that the region be added as a paired region for your source region. See Get Help, Search Forums, and Contact Support for more information.
