look, i never use RMAN before as well as dd for RAW, that why i'm asking your opinion. Is there someone else here have experiance on this?

As far as i'm concern RMAN:
- use another DB to store it catalog -> therefore it requre another space
- RMAN db need to recover it is crash -> else main db unrecoverable
- lots of issue especially bug
If you're afraid of rman god help you with RAC!

What could be simplier in 9i than
run
{
backup database;
}

come on man, get with the times dude, this ain't rocket science.

Build your sandbox database, read the manual and do some testing
