Oracle数据库查看用户状态

一、当前ORACLE用户的状态可查看视图DBA_USERS;一般情况下在使用的正常用户均处于OPEN状态。

SQL> select username,account_status from dba_users;

二、ORACLE数据库用户有多种状态，可查看视图USER_ASTATUS_MAP。

SQL>select * from user_astatus_map;

STATUS# STATUS

-------- ------------------------------

0 OPEN

1 EXPIRED

2 EXPIRED(GRACE)

4 LOCKED(TIMED)

8 LOCKED

5 EXPIRED & LOCKED(TIMED)

6 EXPIRED(GRACE) & LOCKED(TIMED)

9 EXPIRED & LOCKED

10 EXPIRED(GRACE) & LOCKED

三、看看dba_users中该用户的状态等信息

SQL>select account_status,lock_date,profile from dba_users where username='用户名';

1

SQL>selectaccount_status,lock_date,profilefromdba_userswhereusername='用户名';

发现就是今天才锁定的，帐号状态为“LOCKED(TIMED)”，是密码错误次数超过了系统设置的允许最大次数。

查看现在设置的最大次数

SELECT resource_name,resource_type,limit FROM dba_profiles WHERE profile='DEFAULT';

1

SELECTresource_name,resource_type,limitFROMdba_profilesWHEREprofile='DEFAULT';

找到

FAILED_LOGIN_ATTEMPTS            PASSWORD      10

也就是说，原来允许的最大密码错误次数为10次，超过10次自动锁定帐号。难怪我怎么alter unlock都没用，看来还得先把这限制放宽才行。

把限制参数 FAILED_LOGIN_ATTEMPTS 修改成：unlimited

sql> alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;

1

sql>alterprofiledefaultlimitFAILED_LOGIN_ATTEMPTSunlimited;

或 修改成比较大次数：100000

sql>alter profile default limit FAILED_LOGIN_ATTEMPTS 100000;

1

sql>alterprofiledefaultlimitFAILED_LOGIN_ATTEMPTS100000;

再执行如下

SQL>alter user 用户名 account unlock;

1

SQL>alteruser用户名accountunlock;

就可以正常登录了。
