Good. First recover the database then you can access the data. It would appear that you are missing the online redo logs and archived redo logs if they exist. I don't think that you mentioned if this database is running in archivelog mode or noarchivelog mode.

You can re-create the password and init.ora parameter file.

If the database was closed at the time (and had been shutdown cleanly) that the disk/volume/partition was lost, instance recovery should not be required and you may be able to open the database resetlogs (might have to fake recovery to pull that off) which will re-create the online redo logs for you.

Before you do anything as far as recovery - again back up the datafiles, controlfiles that you do have.

A support analyst would be able to walk you through this better/faster than usenet can.
