SYSTEM01.DBF corrupted

SYSTEM01.DBF corrupted

Posted by PDSERVICE on Jul 21, 2021 In
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 data files.
 
 
 pls 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.
