,oracle_username||' ('||s.status||')' oruser
,os_user_name osuser
,machine computer
,l.process unix
,'||s.sid||','||s.serial#||' ss
,r.name rs
,to_char(s.logon_time,'yyyy/mm/dd hh24:mi:ss') time
from v$locked_object l
,dba_objects o
,v$session s
,v$transaction t
,v$rollname r
where l.object_id = o.object_id
and s.sid=l.session_id
