Oracle Database Discussions

Hi,

I need to know if exist an Oracle query that allows me to show open transactions (uncommitted)

I use this query:

 select t.start_time,s.sid,s.serial#,s.username,s.status, s.sql_id
 from v$transaction t, v$session s
 where s.saddr = t.ses_addr

BUT I'd like to know if there are uncommitted transactions 3 days ago.

Thanks in advance!
