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。
