下面3个语句是我经常使用来解决oracle锁问题的 -- 注意你的用户有没有权限问题
1. 查看被锁的表(我是用SYS用户)
SELECT p.spid, a.serial#, c.object_name, b.session_id,
b.oracle_username,
b.os_user_name
FROM v$process p, v$session a, v$locked_object
b, all_objects c
WHERE p.addr = a.paddr AND a.process =
b.process
AND c.object_id = b.object_id
2. 查看是哪个进程锁的
SELECT sid, serial#, username, osuser FROM
v$session where osuser = 'tangpj'
3. 杀掉这个进程 alter system kill session 'sid,serial#';
