数据使用的人多的时候经常会用到的……

SELECT *

    FROM (SELECT /*+ rule */
    s.username,
    decode(l.type, 'TM', 'TABLE LOCK', 'TX', 'ROW LOCK', NULL) lock_level,
    o.owner,
    o.object_name,
    o.object_type,
    s.sid,
    s.serial#,
    s.terminal,
    s.machine,
    s.program,
    s.osuser
FROM v$session s, v$lock l, dba_objects o
    WHERE l.sid = s.sid
        AND l.id1 = o.object_id(+))
           WHERE lock_level IS NOT NULL;
