restore – Is it possible to attach Oracle database files after a clean install


I had an Oracle 10g instance on my Win2008R2 server. Unfortunately, the server crashed and we had to re-install the operating system on the C: drive. The oracle files are on drives other than C.

The other drives (except C) are restored from disk backups. I don’t have a dump file, I only have the Oracle data files such as USERS01.DBF and the Oracle control files.

Now I am trying to find a way to install Oracle again on the server but I am just wondering about how I can attach the current .DBF files to the new Oracle instance? Is this possible? If so, how can I attach the current .DBF files to Oracle?

Currently there is no “OracleService” on services.msc and no listener as well. But previos the previous Oracle instance was installed on the F drive so I still have the Oracle binaries and data files on the F drive.

I would really appreciate if you could provide any information about this.
