Backup controlfiles and recovery? [message #102952]

I'm trying to figure out what the best way to backup a controlfile is to ensure it will be suitable to use for recovery. I can't just make a copy of a controlfile with the OS commands while the database is up, right? If I use "backup controlfile to " will that give me a binary copy of the controlfile that IS valid for recovery?

Definitely Yes..
You can use backup controlfile to '---any Path ---'
which will create you a binary copy of your control file.
Or You can use "backup controlfile to trace;"
which will create a tracefile in your udump dir. wherein you will find the syntax for creating a control file and u can change it accordingly.

try it out.

I wont suggest you taking "backup controlfile to trace"
command since it will create a "create controlfile" statement in trace files and if you run this statement for rebuilding controlfile you will have to do resetlogs. I would rather suggest taking backup through "alter database backup controlfile to <dest>" which will allow you to take backup of controlfile in binary format.
