If you have lots of money, call Oracle. They will bring a tool and get
your data our of the old datafiles. It costs big bucks but worth it if you
have to get the data.

Hello Riyaj,
I have no available database at this moment. It´s not working, I have only
the datafiles asociated with the
previous one (it´s all I could save from my formated computer).
I know that I had corrupted blocks because I run the DBVERIFY utility, and
it showed me which blocks were
corrupted in the system01.dbf file.
I tried to do a backup but it was impossible for me...
What I have trying to is the creation of a new database and overwriting the
previous datafiles on the new ones,
but of course, it doesn´t work.
I suppose If it were possible, then utilities such as backup.. wouldn´t have
many sense..
Anyway, if you have any suggestions I would like to listen to it, and if you
don´t have, a lot of thanks,
