1、查证目前系统对于user用户的状态：

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

2、解除对于user用户的锁定：

conn sys/sys@ora11g as sysdba;

alter user scott account unlock;

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

ACCOUNT_STATUS:EXPIRED

3、连接user用户：

conn user/user@orac11g;

conn user/usernew@orac11g;

此次可以正常连接此用户。
