Re: simulate rman backup

Another feature is that there is a rman directive that will parse / test your command without actually running it. For the validate database (aka backup validate) there is also the parameter for "logical", which does additional checks on table and index sanity. This will sometimes find errors that previously could only be found when doing a index validation. I will see if I can find my sample code that uses these features.
