fast refresh of materialized view running slow

edited Jan 9, 2012 7:16PM in Database DataWarehousing (MOSC) 1 commentAnswered
we do a refresh of the materialized view every day, and it usually took 15 minutes. However, today it took 3 hours.I done some research and saw this as a data issue.  If the number of data changed since yesterday is huge, it would be like a completed refresh.

To see if this is true for our case, is there a way to query how many rows was refreshed yesterday?

thanks
