Thanks for reply.
what i am thinking is to go for recovery.
steps are:
restore backup and control file from most recent bakcup.
recover database using backup controlfile until cancel ;
so it will apply all the archives.
alter database open reset logs;
--- i am not clear on one question.
if i loss control file in my DB, is there any transaction will happened. is it possible to insert/select/update transaction will happen against the DB. i guess it won't happend.
in that case i will go for recreation of control file.
otherwise i will perform recovery.
is this way is correct. could you please tell am i thinking is wrong?
