plsql表锁被占用_PLSQL记录被另一个用户锁住的问题 死锁 锁表

1、找出数据库的serial#,以备杀死：

select t2.username,t2.sid,t2.serial#,t2.logon_time from v$locked_object t1,v$session t2 where t1.session_id=t2.sid order by t2.logon_time;

2、杀死该session:

alter system kill session 'sid,serial#'

---------------------

查看锁表进程SQL语句

select sess.sid,

sess.serial#,

lo.oracle_username,

lo.os_user_name,

ao.object_name,

lo.locked_mode

from v$locked_object lo,

dba_objects ao,

v$session sess

where ao.object_id = lo.object_id and lo.session_id = sess.sid;

杀掉锁表进程：

如有记录则表示有lock，记录下SID和serial# ，将记录的SID替换下面的?号，即可解除LOCK

有几个写几个，用逗号间隔即可

alter system kill session ‘?,?,?’;
