今天测试库有个账户的密码忘了,试了十几次就开始提示:

ERROR:
ORA-28000: the account is locked

意思明显就是账户被锁了,可能是用户的资源设置中对密码重试次数做了限制。

验证:

SQL> select a.username, b.profile, b.resource_name, b.limit
  2  from dba_users a, dba_profiles b
  3  where a.username = 'GALTTEST' and a.profile = b.profile;
GALTTEST  DEFAULT    COMPOSITE_LIMIT          UNLIMITED
GALTTEST  DEFAULT    SESSIONS_PER_USER        UNLIMITED
GALTTEST  DEFAULT    CPU_PER_SESSION          UNLIMITED
GALTTEST  DEFAULT    CPU_PER_CALL              UNLIMITED
GALTTEST  DEFAULT    LOGICAL_READS_PER_SESSION UNLIMITED
GALTTEST  DEFAULT    LOGICAL_READS_PER_CALL    UNLIMITED
GALTTEST  DEFAULT    IDLE_TIME                UNLIMITED
GALTTEST  DEFAULT    CONNECT_TIME              UNLIMITED
GALTTEST  DEFAULT    PRIVATE_SGA              UNLIMITED
GALTTEST  DEFAULT    FAILED_LOGIN_ATTEMPTS    10
GALTTEST  DEFAULT    PASSWORD_LIFE_TIME        180
GALTTEST  DEFAULT    PASSWORD_REUSE_TIME      UNLIMITED
GALTTEST  DEFAULT    PASSWORD_REUSE_MAX        UNLIMITED
GALTTEST  DEFAULT    PASSWORD_VERIFY_FUNCTION  NULL
GALTTEST  DEFAULT    PASSWORD_LOCK_TIME        1
GALTTEST  DEFAULT    PASSWORD_GRACE_TIME      7

确实如此,只允许10次尝试,之后账户就会被锁。

解锁方法很多,通过PLSQL Developer工具解锁可能是最简单、最直观的。

1、用管理员账户登录PLSQL Developer(登录名可以为system,选择类型的时候把Normal修改为Sysdba)。

2、左侧选择My Objects,查看Users文件夹。

3、选择GALTTEST用户,右击点击”编辑“;

4、把“帐户被锁住”的勾去掉;(也可以修改密码)。

5、点击“应用”再点击“关闭”;

6、重新登录就可以通过验证了;

其实使用sqlplus命令行解锁也很简单,用管理员账号sysdba角色登录,执行alter user GALTTEST account unlock;,,即可解锁。

另外,使用如下命令将profile的FAILED_LOGIN_ATTEMPTS属性值修改也可以达到过滤重试次数的限制。


ALTER PROFILE DEFAULT LIMIT FAILED_LOGIN_ATTEMPTS UNLIMITED

附:创建profile的SQL:

create profile test limit;

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
