Hi ladies and gentlemen, I *really* appreciate the feedback including one by private e-mail! It's helped a lot in resolving our DBAs' concerns.
Yesterday, we configured RMAN/TDPO (our first TDPO setup) and I must say the performance flies with use of multiple parallelized streams! I'd only previously set up TDP-MSSQL (which is pretty good, too.) The point regarding continuing to use some form of additional backups outside of TDPO for 'insurance' purposes is a good one, and we will continue to do so. The Redbooks tip was a good one. I've worked with IBM gear for over 10 years but for some reason, hadn't occurred to me to look there. I guess I'm too used to knowing the stuff that I normally need to know. :-) This database isn't on storage that allows for BCV/FlashCopy type snapshots, unfortunately, or we'd leverage that. A pretty good idea, though. (We have various EMC, IBM, and Hitachi enterprise disk storage but not for this particular Oracle database -- historical reasons partly tied in to fairly messy politics.) I think we're on the right track now, and thanks again for your assistance! Cheers, -Dan
