Oracle锁表 解锁sql

今天又遇到了Oracle数据库的表被误操作锁住了，在此记录下使用的锁表语句

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;

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;
 
alter system kill session '31,71';
