Oracle 解锁Record is locked by another user?

Oracle 解锁Record is locked by another user?

在操作ORACLE数据库的时候，由于执行完，没有COMMIT，直接把PL/SQL关闭掉，后来导致那张表被锁住，当编辑时就会出现这个信息，record is locked by another user！
当出现这种情况的时候，只要操作下面几个步骤就可以解锁了。

1.查看被锁住的表：外部邮件发件箱表OA_NET_MAIL_FJX
SELECT A.OBJECT_NAME, A.STATUS, V.SESSION_ID 
  FROM ALL_OBJECTS A, V$LOCKED_OBJECT V 
WHERE A.OBJECT_ID = V.OBJECT_ID 
   AND A.OBJECT_NAME LIKE 'OA_NET_MAIL_FJX';

2.查看锁：
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; 


3.根据session_id(SID) kill掉这个session：
alter system kill session 'sid,serial#' ：
alter system kill session '26,53109';

4.查看表大小：
