sys.v_$session.serial#,
decode(v$lock.type,

rtrim(object_type) || ' ' || rtrim(owner) || '.' || object_name object_name,
decode(lmode,
0, 'None',

6, 'Exclusive', 'Unknown') RequestMode,
ctime, block b
from v$lock, all_objects, sys.v_$session
where v$Lock.sid 6
and sys.v_$session.sid = v$lock.sid
and v$lock.id1 = all_objects.object_id;
