Oracle Database Discussions

Hi,
in 10g R2 on Win 2003,
can we used dvf to verify if controlfile is corrupted or not ?
I had this in alertolog :

 
Tue Oct 05 10:05:25 2010 
Errors in file d:\oracle\product\10.2.0\admin\MYDB\bdump\opermst_arc0_5616.trc: 
ORA-00227: corrupt block detected in control file: (block 1, # blocks 1) 
ORA-00202: control file: 'D:\BASES\MYDB\CTL\CONTROL02.CTL' 

But database did not stop.
I want to know if CONTROL02.CTL' is still corrupted or not ?
Should I absolutely renew it ?

Thanks.
