select l.object_id as object_id, o.object_name as name,o.object_type as object_type,s.machine as machine, 
      l.oracle_username as username,l.os_user_name as osuser,s.logon_time as logon_time, 
      decode(l.locked_mode,0,'None', 
            1,'Null', 
            2,'Row-S(SS)', 
            3,'Row-X(SX)', 
            4,'Share', 
            5,'S/Row-X(SSX)', 
            6,'Exclusive','모름') as Lock_Mode 
from  v$locked_object l, dba_objects o, v$session s 
where  l.object_id = o.object_id        
and    l.session_id = s.sid 

order by o.object_name;
