Database is not started because of datafile corruption !!!

Question

Dear friends ,
I m using oracle 9.2.0.1.0 . Suddenly for power failure my pc is restarted and that moment , when i m going to startup the database i got the following error :
SQL> startup
ORACLE instance started.
Total System Global Area 135338868 bytes
Fixed Size 453492 bytes
Variable Size 109051904 bytes
Database Buffers 25165824 bytes
Redo Buffers 667648 bytes
Database mounted.
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'D:\ORACLE\ORADATA\SCHEME\SYSTEM01.DBF'
I m running the following recovery option but the problem is not solved :
SQL> recover database until cancel using backup controlfile;
ORA-00279: change 8853194 generated at 08/31/2008 17:31:32 needed for thread 1
ORA-00289: suggestion : D:\ORACLE\ORA92\RDBMS\ARC00116.001
ORA-00280: change 8853194 for thread 1 is in sequence #116
Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
cancel
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: 'D:\ORACLE\ORADATA\SCHEME\SYSTEM01.DBF'
ORA-01112: media recovery not started
I use AUTO option , but no benefit .
I have no cold or RMAN backup of my database , and also database is not in archive log mode .
In this moment , is there any solution to startup my database ?
waiting for ur kind reply ... ...

Answer 1

Check the alert.log for this database. What were the last few entries ? We need to know which redo log was sequence #116. You would be able to use that for recovery.
We presume that there are NO filesystem corruption errors and NO missing datafiles / redologs.
