一般Oracle数据库默认是10次尝试失败后锁住用户;

1、查看FAILED_LOGIN_ATTEMPTS的值

select * from dba_profiles;

2、修改为30次alter profile default limit FAILED_LOGIN_ATTEMPTS 30;

3、修改为无限次(为安全起见,,不建议使用)alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;

用户解锁:

alter user user_name account unlock;

Oracle 密码期限设置:

Oracle 11G创建用户时缺省密码过期限制是180天, 如果超过180天用户密码未做修改则该用户无法登录。

可通过

SELECT * FROM dba_profiles WHERE profile='DEFAULT' AND resource_name='PASSWORD_LIFE_TIME';

语句查询密码的有效期设置,LIMIT字段是密码有效天数。

在密码将要过期或已经过期时可通过:

ALTER USER 用户名IDENTIFIED BY 密码;

语句进行修改密码,密码修改后该用户可正常连接数据库。

长久对应可通过:

ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED

语句将口令有效期默认值180天修改成“无限制”。

出于数据库安全性考虑,不建议将PASSWORD_LIFE_TIME值设置成UNLIMITED,建议客户定期修改数据库用户口令。
