select username, account_status from dba_users;

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

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

SQL> alter profile default limit password_life_time unlimited;

Profile altered.

该账户被锁定执行如下sql
alter user 用户名 account unlock;

eg:SQL>  alter user TEST account unlock;

该账户过期执行如下sql
alter user 用户名 identified by 密码;（修改密码通把密码进行重置成密码，改变账号状态有EXPIRED改为OPEN）

下面可以查询系统中的用户和创建的用户，通过created字段可以看到创建的时间，默认从此刻起，6个月后就密码过期了。就会报ORA-28001: the password has expired 的错误:
select * from dba_users t where t.username = 'EPLATFORMTEST'
