ORACLE 如何查询被锁定表及如何解锁释放session



--锁表查询SQL

SELECT object_name, machine, s.sid, s.serial# 
FROM gv$locked_object l, dba_objects o, gv$session s 
WHERE l.object_id　= o.object_id 
AND l.session_id = s.sid; 

--释放SESSION SQL:

alter system kill session 'sid, serial#'; 

例子：
ALTER system kill session '23, 1647';
