Oracle密码过期the password has expired

weblogic连接数据库失败，plsql能正常登陆

java.sql.SQLException: ORA-28001:
the password has expired

网上查了一下，是Oracle11g密码过期的原因

连接Oracle，以Oracle用户登陆，输入以下命令

select * from dba_profiles where profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';

结果显示：

PROFILE

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

RESOURCE_NAME

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

RESOURCE_TYPE

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

LIMIT

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

DEFAULT

PASSWORD_LIFE_TIME

PASSWORD

180

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

结果显示密码有效期是180天

输入命令：

alter profile default
limit password_life_time unlimited;

commit;

再次执行：

select * from dba_profiles where profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';

结果显示为：

PROFILE

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

RESOURCE_NAME

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

RESOURCE_TYPE

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

LIMIT

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

DEFAULT

PASSWORD_LIFE_TIME

PASSWORD

UNLIMITED

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

进行以上步骤之后需要改变密码,否则还会出现password
has expired异常,改变密码的命令

alter user XXXUSER
identified by Welcome1;

如果账号被锁住，则需要解锁命令:

alter user XXXUSER
identified by oracle
account unlock;
