Re: Materialized View+complete refresh

have you checked/created a histogram of the wait events the refresh creates? Where is most of the time spent? (There are several methods v $sesstat, ash, statspack, event10046, ... ) Then it might be easier to target this part of the refresh, instead of just guessing arount.
just an idea,
