SuradechHi Suradech.This error(ORA-01157,ORA-01110) because in controlfile remain information about of '/data/db01/ORABK/perfstat.dbf'.Due to you restored controlfile from backup.You have to re-create controlfile or you can open database without this datafile.(Also there is YEAR2009' tablespaces datafile).You can try following.
1.
sqlplus "/as sysdba"
alter database datafile '/data/db01/ORABK/perfstat.dbf' offline drop;
alter database open;or
2.
sqlplus "/as sysdba"
alter database backup controlfile to trace as '/data/ctrl'; --then edit this file and remove  '/data/db01/ORABK/perfstat.dbf' line(also YEAR2009`s datafile)
shutdown immediate;
startup nomount;
@/data/ctrl;
alter database open resetlogs; also see following metalink note.
