How to find the top SQL statements that have caused most block buffer reads?

January 16th, 2006 By kirtandesai

Select buffer_gets, sql_text
from v$sqlarea
where buffer_gets > 10000
order by buffer_gets desc;

I had to bump up the number of buffer_gets because the above statement returned a LOT of rows.

Select buffer_gets, sql_text, rownum rn
from v$sqlarea
where buffer_gets > 10000
