Query v$session_event to see what else a
session has waited on:
select
sess.username,
sess.sid,
se.event,
se.total_waits,
se.total_timeouts,
se.time_waited/100 time_waited,
se.average_wait
from v$session_event se, v$session sess
where event like '%'
and sess.sid = se.sid
and sess.username is not null
order by username, sid;

Subject: waits vs. logons
I run the following query to compare the total waits for a session verses
the seconds logged on:
select a.sid, a.ontime longon_secs, round(b.waittime) wait_secs
from
(select sid, (sysdate - logon_time)*24*60*60 ontime
from v$session ) a,
(select sid, sum(time_waited)/100 waittime
from v$session_event
group by sid) b
where a.sid = b.sid;
I get the following results:
SID LONGON_SECS WAIT_SECS
---------- ----------- ----------
1 595995 595989
2 595994 471204
3 595994 595585
4 595994 594580
5 595994 595492
6 595994 593639
9 595993 577157
14 4943 1303
24 595844 588441
26 1733 1728
27 5308 2478
29 517269 0
32 53 0
35 415158 13
50 140478 140371
51 719 507
56 14507 8706
59 2269 221
I am very much a novice when it comes to wait statistics. When a session,
for example #51, has been logged on for 719 seconds but has experienced
only 507 wait seconds, what did it do the rest of the time? I am assuming
some kind of work? Any way to determine what?
