A Tale of Two SQLs 2004-05-04 - By Daniel Fink
Waleed,
We don 't have a baseline for rbs i/o, but we can get one the next time the query
runs well. However, if we are generating r/c views of the same blocks (with a
different target scn) over and over, the undo blocks will likely stay in the
cache and we may not see a drastic change in reads.
