Answer 1

my database is not running on rman.What does that mean ? rman is an OS utility, you can use it or not, but it has nothing to do with the database.
i have 2 controlfile & i want to add one more controlfile so i need to copy one of controlfile to my desire location but i m not been able to copy .Yeah... this is the reason that I asked why you needed a copy command : you can use rman for that (and to do backups and copy files as well). In following example a controlfile is added in ASM database :
