oracle user locked(timed)处理

故障现象:

SQL> connect scott/scott
ERROR:
ORA-01017: invalid username/password; logon denied
SQL> connect scott/scott
ERROR:
ORA-28000: the account is locked

表明:Oracle 中 scott用户因密码不对,10次以后,就被locked。

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

ACCOUNT_STATUS                   TO_CHAR(LOCK_DATE,'D PROFILE
-------------------------------- -------------------- ------------------------------
LOCKED(TIMED)                    31-MAY-2004 19:33:53 DEFAULT

这样,表明再添加oracle session时,就报错,无法连接上去。

故障解决:

(1) 给当前用户解锁:

sql> alter user scott account unlock;

(2) 查看当前用户的限制:

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

RESOURCE_NAME                    RESOURCE_TYPE LIMIT
-------------------------------- ------------- ----------------------------------------
COMPOSITE_LIMIT                  KERNEL        UNLIMITED
SESSIONS_PER_USER                KERNEL        UNLIMITED
CPU_PER_SESSION                  KERNEL        UNLIMITED
CPU_PER_CALL                     KERNEL        UNLIMITED
LOGICAL_READS_PER_SESSION        KERNEL        UNLIMITED
LOGICAL_READS_PER_CALL           KERNEL        UNLIMITED
IDLE_TIME                        KERNEL        UNLIMITED
CONNECT_TIME                     KERNEL        UNLIMITED
PRIVATE_SGA                      KERNEL        UNLIMITED
FAILED_LOGIN_ATTEMPTS            PASSWORD      10
PASSWORD_LIFE_TIME               PASSWORD      UNLIMITED
PASSWORD_REUSE_TIME              PASSWORD      UNLIMITED
PASSWORD_REUSE_MAX               PASSWORD      UNLIMITED
PASSWORD_VERIFY_FUNCTION         PASSWORD      NULL
PASSWORD_LOCK_TIME               PASSWORD      UNLIMITED
PASSWORD_GRACE_TIME              PASSWORD      UNLIMITED

表明: 10次以后,就 failed_login_attempts 就报错,锁定用户。

需要修改成:unlimited

sql> alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;

或修改成:次数比较大:100000

sql>alter profile default limit FAILED_LOGIN_ATTEMPTS 100000;

然后再查看资源情况:

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

RESOURCE_NAME                    RESOURCE_TYPE LIMIT
-------------------------------- ------------- ----------------------------------------
COMPOSITE_LIMIT                  KERNEL        UNLIMITED
SESSIONS_PER_USER                KERNEL        UNLIMITED
CPU_PER_SESSION                  KERNEL        UNLIMITED
CPU_PER_CALL                     KERNEL        UNLIMITED
LOGICAL_READS_PER_SESSION        KERNEL        UNLIMITED
LOGICAL_READS_PER_CALL           KERNEL        UNLIMITED
IDLE_TIME                        KERNEL        UNLIMITED
CONNECT_TIME                     KERNEL        UNLIMITED
PRIVATE_SGA                      KERNEL        UNLIMITED
FAILED_LOGIN_ATTEMPTS            PASSWORD      UNLIMITED
PASSWORD_LIFE_TIME               PASSWORD      UNLIMITED
PASSWORD_REUSE_TIME              PASSWORD      UNLIMITED
PASSWORD_REUSE_MAX               PASSWORD      UNLIMITED
PASSWORD_VERIFY_FUNCTION         PASSWORD      NULL
PASSWORD_LOCK_TIME               PASSWORD      UNLIMITED
PASSWORD_GRACE_TIME              PASSWORD      UNLIMITED

16 rows selected

SQL>

这样就不会用:client端因输入密码错误,造成用户被locked(timed)
