oracle 解除对scott/tiger用户的锁定

1、查证目前系统对于scott用户的状态：

select * from dba_users where upper(username)='scott';

account_status:expired & locked

2、解除对于scott用户的锁定：

conn sys/bitservice@ttonline as sysdba;

alter user scott account unlock;

select * from dba_users where upper(username)='scott';

account_status:expired

3、连接scott用户：

conn scott/tiger@ttonline;提示该用户已经过期，请重新输入新的密码：tiger

conn scott/tiger@ttonline;此次可以正常连接此用户。

4、查看scott用户的状态：

conn sys/bitservice@ttonline as sysdba;

select * from dba_users where upper(username)='scott';

account_status:open
