ORA-28000: the account is locked

第一步：使用PL/SQL，登录名为system,数据库名称不变，选择类型的时候把Normal修改为Sysdba;

第二步：选择myjob,查看users;

第三步：选择system,右击点击“编辑”；

第四步：修改密码，把“帐户被锁住”的勾去掉；

第五步：点击“应用”再点击“关闭”；

第六步：重新登录就可以通过验证了；

第二种

ALTER USER username ACCOUNT UNLOCK;

 

 

第三种

 

 

在plsqldeveloper中要是以scott/tiger登录时提示ora-28000 the account is locked。

 

解决办法：

 

新装完Oracle10g后，用scott/tiger测试，会出现以下错误提示：

       oracle10g the account is locked

       oracle10g the password has expired

原因：默认Oracle10g的scott不能登陆。

解决：

（1）conn sys/sys as sysdba; //以DBA的身份登录

（2）alter user scott account unlock;// 然后解锁

（3）conn scott/tiger //弹出一个修改密码的对话框，修改一下密码就可以了

 

在运行里面输入cmd在DOS模式下输入sqlplus，以system用户名登录，密码是刚装oracle时自己填写的密码orcl，登录进去以后。

 

SQL> conn sys/sys as sysdba;       （分号是必须的但是我是以system登录的所在这不应该写connsys/sys as sysdba应该写connsystem/orcl as sysdba;）

        Connected.

SQL> alter user scott account unlock;

        User altered.

SQL> commit;

        Commit complete.

SQL> conn scott/tiger//请输入新密码，并确认后OK

Password changed

Connected.

 

 

这时再到plsqldeveloper里面以scott/tiger登录就可以了。。。。。

 

 

 

Oracle 10g 默认安装带来的用户名/密码
