If you cannot have your DBAs shutdown the database for the duration of your backup, perhaps they can put it into "hot backup mode"? This puts changes into separate files so that you can get a consistant backup of the 6 files oracle uses. You can't backup a "live" oracle database because if these 6 files aren't consistant, oracle won't touch them.
There is something about "PP size". I've yet to see this explained very well (I'm more of a Solaris guy). Essentially, you can only extend a filesystem so far. If you know you're going to expand a given filesystem, you can go in and mess with the numbers (when you build the filesystem) and make them big enough to expand things down the road (and what exactly this costs you; why you wouldn't just do this all the time, I don't have a clear understanding of either). If you just accept the defaults, then at some point, if you expand and expand and expand, you'll eventually reach a point where you can't expand anymore (something runs out of fingers and toes to count on). Whereas if you build a new filesystem from scratch, and you make it big, the defaults will bump up to some bigger numbers.
Sorry I don't have a better explaination; I don't understand it well myself. Perhaps someone who does understand all this can explain it better. I'm just thinking that perhaps this is what IBM is talking about.
Of course, you can call IBM back and ask them to explain it to you...
PS: It is my understand that a JFS2 filesystem doesn't have all this. I don't know when they added JFS2 or if that is an option for you.
