In September 2016 I had a serious problem in my company's Oracle Database .
The main Database has beeb corrupted as well as its Backup.
So I met the tool that saved me: PRM-Dul from Parnassus Data.
If your Database is corrupted and you need to recover it, use this tool.
DBRECOVER Recovery Options
For Oracle incidents, start with the DBRECOVER for Oracle trial to verify table visibility, row previews, and export readiness on copied datafiles. For MySQL and InnoDB incidents, DBRECOVER for MySQL is free software and can inspect.ibd files, ibdata1, and database directories locally.
When the case is urgent, preserve the original files first, work from copies, and contact paid emergency support with the database version, platform, error messages, file list, and recovery objective.
