Recover Oracle datafile
unfortunately my hard disk's server crashed, and I do not have any backup,
I recovered oradata folder in crashed hard disk, which is contains DBF, Ora and log files as attachment picture.
My Oracle database version is 10.2.
would you please guid me how can I recover my databse step by step?
Your oradata directory seems to be under the same path as your oracle home:
Is this true or do you have the original oracle home on another disk (perhaps 'C:'?)
The procedure would be to just copy your recovered files from disk 'F:' to their original location and try start the database.
