That is exactly what we are experimenting with, in a demo starting Monday. We've been using the TDPO shim for years, and have never gotten free of occasional manual reconciliation, which appears to match the general experience. This is constant sand in the vaseline for the Oracle admins' experience, and no pearl has accreted thus far. Furthermore, if the dedupe works as well as advertised (hah) then there are a variety of toys we can let the Oracle folks use, which are usually prohibitively expensive in disk. I don't know the buzzwords, but Flash Recovery Area seems to be one of them. Basically, if you've got lots of space to store a bunch of fulls all over the place, Oracle lets you play fun games with them. at 20:1 dedupe ratio, this would not be an issue. - Allen S. Rout
