Recovering from different datafiles

Posted by PDSERVICE on 4月 18, 2017 In

We recently had a disaster scenario. Someone deleted the entire Oracle installation including the backup, all with Linux rm command.

We saved the files with some undelete utility (reiserfsck --rebuild-tree). Unfortunately some files are missing or are corrupt.

I have all the datafiles, but:

- some of them are 1 day old

- some of them are 2 days old

- two are even 1 month old (SYSTEM and UNDO; basically we have an entire valid backup from 1 month, but that's too old)

Is there any way to put these files together so Oracle will work?

Is there any tool (except Oracle's DUL) that can extract data from a dbf file into text, CSV, XML, SQL,... anything?

The data is extremely important so any help from you Oracle experts would be appreciated.

Thanks you very much in advance.
