I haven't got the 8.1.6 documentationso don't know what it says, but you'll only get "snapshot too old" if your rollback segments are too small, or heavily used so that your committing transaction overwrites committed pre-images.

Your rollback segments may well be large enough to avoid the "snapshot too old" problem". Remember that the "fetch across commit" example I gave (and probably the one in the documentation) only makes the the "snapshot too old" situation a possibility (albeit a likely one), it doesn't *guarantee* that it will occur.
