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plsql developer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conn sys/sys as sysdba应该写conn system/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plsql developer里面以scott/tiger登录就可以了。。。。。
