Supported Database Configurations

In the current release, Data Recovery Advisor only supports single-instance databases.Oracle Real Application Clusters (Oracle RAC) databases are not supported.

If a data failure occurs that brings down all Oracle RAC instances, then you can mount the database in single-instance mode and use Data Recovery Advisor to detect and repair control file, SYSTEM data file, and data dictionary failures. You can also invoke data recovery checks proactively to test other database components for data failures. This approach does not detect data failures that are local to other cluster instances, for example, an inaccessible data file.

In a Data Guard environment, Data Recovery Advisorcannot do the following:

Use files transferred from a physical standby database to repair failures on a primary database
Diagnose and repair failures on a standby database
