Urgent, please: what are my options???

Hi all,
I have a 9i on Windows2003 with no backup.
Database was open while drive where redo logs resided was gone. So I lost all 
redo logs.
I shutdown d/b, mounted it, backed up controlfile to trace.
Recreated control file, but when I try to open resetlogs d/base I receive an 
error:

ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'D:\ORACLE_SAN\DATA\SYSTEM\REPD_SYSTEM_01.DBF'

What are my options besides rebuilding d/base???
