分析：

原因是账户密码已过期，数据库采用的是oracle 11g，新增加了账户安全性，密码有效期为180天，之前的oracle 9i/10g都没有这个问题，VCenter安装时vc数据库用户vpxadmin，另外SSO的数据库用户RSA_DBA和RSA_USER，总共三个账号。

查看数据库账户配置：

$sqlplus / as sysdba

select * from dba_profiles WHERE dba_profiles.profile='DEFAULT';

1、查看用户的proifle是哪个，一般是default：

sql>SELECT username,PROFILE FROM dba_users;

2、查看指定概要文件（如default）的密码有效期设置：

sql>SELECT * FROM dba_profiles s WHERE s.profile='DEFAULT' AND resource_name='PASSWORD_LIFE_TIME';

3、可以将密码有效期由默认的180天修改成“无限制”：

sql>ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

4、解除账户锁定：

sql> alter user vpxadmin  account  unlock;

修改完成后虽然是立即生效，但是VC不一定能启动，我的是这样，可能跟VC的某些服务有关，重启系统就好了。
