Certify Applications for Compatibility Between Shared and Dedicated Autonomous Databases

Considering that your application is already certified to use Autonomous Database on Shared deployment, the following table helps you evaluate if your application can be certified to use Autonomous Database on Dedicated deployments too.

The table below lists the options and features that are either:
  • Currently available only in Shared Autonomous Database deployments, or
  • Has differences in functionality with dedicated Autonomous Database deployments both in Public Cloud and Cloud@Customer.

Note:

There are also features only supported in dedicated Autonomous Database deployment and not supported in Shared Autonomous Database deployments. However, as the presumption is that you are evaluating to certify your application on both the deployments, starting with Shared deployments, we are not discussing them here.
