Thanks. One of the concerns someone raised is "All old rows in database will have slowness the first time they are read or updated due to conversion to 10g.". I am trying to find out if this indeed is true, and one of the things came to mind was if rowid format changed, which doesn't seem to be the case. - Deepak --- Ric Van Dyke <Ric.Van.Dyke@xxxxxxxxxx> wrote: > If you are asking "has the rowid format changed in > 10g?" then the answer is no. > __________________________________________________ Do You Yahoo!?
