Finding long running queries inside procedure

Question

Hi All,
Without using trace file or not modifying the existing procedure, is there any way to find out the query which is taking longer time (say out of 20) inside oracle procedure?
Thanks in Advance,
Geetha

Hi,
if you are on your development or test database the best tool (after the sql trace :)) is DBMS_PROFILER. It's easy to use and shows you how long does it take to execute every line of procedure. It helps to find not only slow SQL but also bottlenecks in pl/sql code.
Another option could be Active Session History that every 1s creates snapshot of active sessions. You have to open new session, run the procedure and use query like this:
select *
from v$sql s
    (select sql_id, max(sample_time) - min(sample_time) as duration
    from v$active_session_history
    where sid = sys_context('userenv', 'sid') --SID of the session that executed the procedure
    ) ash
where s.sql_id = ash.sql_id
order by duration desc;
