I want to recover our some Oracle dbf and tried DUL5.1.

But something wrong.

Log is nelow

You can get more documents fromDBRECOVER for Oracle

PRM: Warning: scaned 10MB data, couldn't find file header for users.dbf

DB file version info

File: users.dbf, db version: 0

File is not exist: mlkj

How about the db version? is the dbf header corrupted?

Can you unload this datafile?

And would you like to try with this video?https://www.youtube.com/watch?v=jOT6k-KF8Hg

Db version is 9.

I tried the video.

But we lost SYSTEM01.DBF.

You can use non-dictionary mode, and specify the TS# and file# for that datafile .

Scan was finished successfully.

But trees are DB_20190721191326 - lob segment

And lob segment is empty.

Right click the DB_20190721191326 and select scan extent, then you may get some table.

I could get some table!!

But it is garbled.

And Can I get these data?

Right click the table, you can unload the data into file or data bridge them to another Oracle db.

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.
