Urgent -Failed to open database

Hi all,
When I tried to open database I got:

Quote:

---

ORA-01589: must use RESETLOGS or NORESETLOGS option for database open.

---

I tried to :

Code:

---

alter database open resetlogs;

---

and I got:

ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1:
'E:\ORACLE\PRODUCT\10.1.0\ORADATA\FILERPRO\SYSTEM0 1.DBF'

---

Then I did:

Code:

---

SQL>RECOVER DATAFILE 1;

---

and It throws:

Quote:

---

ORA-00283: recovery session canceled due to errors
ORA-01610: recovery using the BACKUP CONTROLFILE option must be done

---

And if you are there and did not run away ;) I should say I issued:

Code:

---

alter database recover using backup controlfile

---

and this time my lovely server said:

ERROR at line 1:
