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;

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.
