ORA-28000: the account is locked-的解决办法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）connscott/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 connscott/tiger//请输入新密码，并确认后OKPassword changedConnected.这时再到plsql developer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??
