Oracle密码过期及EM无法登陆

评分 5.00, 满分 5星 1 票 No comments

关键字:EM无法登录,提示ORA-28001: the password has expired (DBD ERROR: OCISessionBegin)

以上提示 参见本文。
Oracle 11g 默认安装 用户密码有180天的过期限制。
测试用库实在有些不便。

--sys DBA 身份连入
sqlplus sys/password@SID as sysdba
--查看数据库目前的口令期限
select * from dba_profiles where profile = 'DEFAULT' and resource_name = 'PASSWORD_LIFE_TIME';
--查看用户的状态,发现DBSNMP和SYSMAN两个帐号都已经过期
select username, account_status from dba_users;

--修改用户的口令期限为无限制
alter profile default limit password_life_time unlimited;

--修改DBSNMP和SYSMAN两个帐号的口令
alter user dbsnmp identified by dbsnmp;
alter user sysman identified by sysman;

执行以上操作后,重启计算机、服务器即可。

如果仍然提示无法连接实例,并且dbsnmp sysman 用户被锁定 LOCKED(TIMED)。
极有可能是EM 的配置文件中dbsnmp sysman的密码 与实际的不同。
此时重置EM 配置文件。

--sqlplus 中运行
emca -config dbcontrol db
--根据提示 输入各用户名的 密码。

附: Oracle 默认安装带来的用户名/密码
