Data Recovery Advisor is the Recovery Manager component that diagnoses data failures such as missing or corrupt files and corrupt blocks, proposes repair options and can run them. It is driven through the RMAN commands LIST FAILURE, ADVISE FAILURE, REPAIR FAILURE and CHANGE FAILURE.

Migrations care mainly for estates that stay on Oracle in Azure, on virtual machines or Oracle Database@Azure, where RMAN remains the backup tool and operational runbooks referencing these commands have to be rewritten. For the PaaS targets the topic disappears, because backup and repair are platform-managed.

Oracle's 19c Upgrade Guide lists the advisor as deprecated starting with 19c (notice dated July 2023), and the 26ai guide desupports it (also July 2023). The four RMAN commands are removed and Oracle names no replacement feature.

RMAN Data Recovery Advisor, born before 11.2, diagnosed block and file corruption and proposed RMAN repairs. It kept a failure catalog and offered automated repair advice, sparing administrators some detective work.

Deprecated in 19c and desupported in 26ai, it departed without an Oracle replacement. On Managed Instance, DBCC CHECKDB repair options cannot run because the database cannot enter SINGLE_USER mode; suspected corruption goes to Azure support.

It is survived by Azure SQL Managed Instance, only by workaround, through automatic backups, redundancy and replicas. Oracle Database@Azure survives partly: RMAN and managed backups remain, but the failure catalog and automated advice do not.
