Oracle 11g用户修改密码及加锁解锁功能实例代码_oracle_

 alter user identityName identified by password; —–修改密码 alter user identityName account unlock; —–解锁 alter user identityName account lock; —–加锁 identityName:需要修改的用户； password：新设密码；

 SQL> conn sys/sys as sysdba Connected. SQL> show user USER is "SYS" SQL> alter user hr account unlock;（解锁） User altered. SQL> alter user hr identified by *password*;（更改密码，这一步是必需的，否则hr模式还是不能使用的） User altered. 到这里hr模式就可以使用了,试试： SQL> conn hr/*password* Connected. SQL> show user USER is "HR" ---------------------------------- 相反的 SQL> alter user hr account lock;（上锁） User altered. SQL> alter user hr password expire;（密码失效） User altered. SQL> conn hr/*password* ERROR: ORA-28000: the account is locked Warning: You are no longer connected to ORACLE.
