oracle 查看表是否被锁定

1.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;

2.查看哪个进程锁的

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;

3.杀掉进程

alter system kill session 'sid,serial#';
