Data Recovery Advisor can diagnose failures such as the following:

Components such as datafiles and control files that are not accessible because they do not exist, do not have the correct access permissions, have been taken offline, and so on

Physical corruptions such as block checksum failures and invalid block header field values

Inconsistencies such as a datafile that is older than other database files

I/O failures such as hardware errors, operating system driver failures, and exceeding operating system resource limits (for example, the number of open files)

Note that Data Recovery Advisor may detect or handle some logical corruptions. But in general, corruptions of this type require help from Oracle Support Services.

I would say: CDE
