oracle中表被锁了怎么办



查询哪个表被锁

select * from v$locked_object;

1)锁表查询的代码有以下的形式：
select count(*) from v$locked_object;
select * from v$locked_object;搜索
(2)查看哪个表被锁
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;
(3)查看是哪个session引起的
select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
(4)杀掉对应进程执行命令：
alter system kill session'1025,41';其中1025为sid,41为serial#.

ok问题解决！！！
