Try this:
SELECT l.SID,s.serial#,s.username,s.terminal,

        DECODE(l.TYPE,'RW','RW - Row Wait Enqueue', 'TM','TM - DML Enqueue', 'TX','TX - Trans Enqueue', 'UL','UL - User',l.TYPE||'System') res,  

        SUBSTR(t.NAME,1,20) TAB,u.NAME owner, 
        l.id1,l.id2, 
        DECODE(l.lmode,1,'No Lock', 
                2,'Row Share', 
                3,'Row Exclusive', 
                4,'Share', 
                5,'Shr Row Excl', 
                6,'Exclusive',NULL) lmode, 
        DECODE(l.request,1,'No Lock', 
                2,'Row Share', 
                3,'Row Excl', 
                4,'Share', 
                5,'Shr Row Excl', 
                6,'Exclusive',NULL) request 

FROM (select /*+ no_merge */ * from v$lock) l, (select /*+ no_merge */ * from v$session )s,
sys.USER$ u,sys.obj$ t
WHERE l.SID = s.SID

AND s.TYPE != 'BACKGROUND' 
AND t.obj# = l.id1 
AND u.USER# = t.owner#
