Open cursor query - oracle 10g

Question

Could anyone tell me which is the right query for fetching open cursor:
1.
select max(a.value) as highest_open_cur,s.sid, s.username, oc.sql_text, s.logon_time, s.status, s.machine
from v$sesstat a, v$statname b, v$parameter p, v$session s, v$open_cursor oc
where a.statistic# = b.statistic#
and b.name = 'opened cursors current'
and p.name= 'open_cursors'
and username in ('USER_ID')
and s.sid = a.sid
-- and s.status <> 'KILLED'
and oc.sid = s.sid
group by s.sid,s.username, oc.sql_text, s.logon_time, s.status, s.machine
order by s.logon_time desc
2.
SELECT user_name,sid,sql_text,count(1) total,sysdate snap_time
FROM v$open_cursor
WHERE user_name IN ('USER_ID')
GROUP BY user_name,sid,sql_text
HAVING count(1)>0;
The issue is inthe secind query we have had hardly any open cursors and from the first query we are getting quiet a lot.
Would like someone to explain me the the interpretation of both the queries.
Does Oracle 10g has a different interpretation of these tables.
How should we be reading the open cursors? and
Does anyone feel there is a better way to check for open cursors ?

open cursors ?Forget cursors, if your purpose is to do some kind of research for performance tuning, just generate either the Enterprise Manager ASH or ADDM reports.
