I think your data file is corrupt ,
you have to drop the data file it first before you open database .

just MOUNT the database , 
then issue this command :
SVRMGR> ALTER DATABASE yourDB DATAFILE 'D:\ORACLE\ORADATA\VTP2\RBS01.DBF'  OFFLINE DROP

then you can issue ' Alter Database Open '

the problem become easier if you have backup of that datafile .

never forget to make backup : )
