Welcome to the forum. Please read our OraFAQ Forum Guide and How to use [code] tags and make your code easier to read

The live controlfile is continually changing, but RMAN needs a stable copy of the ontrolfile to backup. So it creates the snapshot from memory, and use that to create rhe backup.

What documents did you read?
