The SGA monitoring counters are not fully serialized (imagine an overhead otherwise). The numbers are "about" and not 100% correct. You can insert and later rollback - the counters will add up.
I saw some INSERTS into a table I know was not being inserted into. I broke the query down a bit and sure enough the SQL in gv$sql was not related to the table which was being returned by the object name in the query below. This is a 10.2.0.3 database, perhaps there are some changes in the way things need to be joined in 10G with this query. If anyone sees an obvious problem let me know. Thanks, Ethan
