Last week we had disk failure. Unfortunetly I have lost arch logs and trc files. When we were trying to start the database, we starting getting the following error:

ORA-01113 file 8 needs media recovery.

After reading arround we tried the followings:

Startup nomount;
recover database until cancel;
alter database open resetlogs;

When we tried again, we started getting new error:

ORA-01194: file 1 needs more recovery to be consistent;

It is complaining onSYSTEM01.DBF file now. Please guide me how can open the database without latest logs and Tracefiles;

Thanks in Advance.
