Due to a recent power outage our storage server got corrupted.
OS: Windows
DB: Oracle 11g R2
Version: 11.2.0.4
Incident
SYSTEM01.DBF is corrupted and we have all other DBF files.
RMAN backup files are also corrupted
No dump files available.
So we would like to use dbrecover tool to extract the data from all the datafiles.
Please try the software first:https://s.dbrecover.com/dbrecover-for-oracle-latest-dist.zip
Please try Dictionary Mode first. It may work even system01.dbf is corrupted .
The corrupted file SYSTEM01.DBF shows 0 KB so it gives this message.
If you have any old system01.dbf, you can use it. Otherwise you have to use non-dict mode, which lost table name and column name.because all those metadata stored in system01.
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.
