案例：

客户想通过alter table def.d read only;的方式停表，然后expdp迁移走部分表。

语句找到sid/serial#

SELECT s.sid, s.serial#,s.username

FROM v$transaction t, v$session s,v$lock l

WHERE t.status = 'ACTIVE' AND t.addr=s.TADDR and l.sid=s.sid and l.id1 IN (SELECT OBJECT_ID FROM dba_objects WHERE object_name = 'D' and OWNER='DEF');

更简单（不用v$transaction）：

SELECT s.sid, s.serial#,s.username

FROM v$session s,v$lock l

WHERE l.sid=s.sid and l.id1 IN (SELECT OBJECT_ID FROM dba_objects WHERE object_name = 'D' and OWNER='DEF');

杀光即可。

alter system kill session '1147,25' immediate;
