Is it possible to attach oracle database file after 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 C: drive. The oracle files are on other drives except than C.

The other drives (except C) are restored from disk backups. I don’t have dump file, I only have 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 oracle was installed on F drive so I still have the oracle binaries and data files on F drive.

Really appreciate if you can provide any information on this.
