先发句牢骚，明明刚才写完了，发布的时候却说没登陆，一下子全没了。

今天打开EM发现提示 

ORA-28001: the password has expired (DBD ERROR: OCISessionBegin)

 

于是查找了一下资料，密码过期导致EM无法登录。ORACLE11G默认的口令期限是180天，为了永久解决这个问题只能修改配置文件。

1、查看目前数据库中的口令期限

SYS@ orcl>select * from dba_profiles where profile='DEFAULT'
  2  and resource_name='PASSWORD_LIFE_TIME';

PROFILE                        RESOURCE_NAME                    RESOURCE         LIMIT
------------------------------ -------------------------------- ------------------------------------------------
DEFAULT                        PASSWORD_LIFE_TIME               PASSWORD    180

 

2、修改成无限制的

SYS@ orcl>alter profile default limit password_life_time unlimited;

3、查看em的两个账号状态sysman和dbsnmp

SYS@ orcl>select username,account_status from dba_users;

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
TEST                           OPEN
TEST2                          OPEN
SCOTT                          OPEN
HR                             OPEN
ORACLE_OCM                     EXPIRED & LOCKED
XS$NULL                        EXPIRED & LOCKED
BI                             EXPIRED & LOCKED
PM                             EXPIRED & LOCKED
MDDATA                         EXPIRED & LOCKED
IX                             EXPIRED & LOCKED
SH                             EXPIRED & LOCKED

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
DIP                            EXPIRED & LOCKED
OE                             EXPIRED & LOCKED
APEX_PUBLIC_USER               EXPIRED & LOCKED
SPATIAL_CSW_ADMIN_USR          EXPIRED & LOCKED
SPATIAL_WFS_ADMIN_USR          EXPIRED & LOCKED
DBSNMP                         EXPIRED
SYSMAN                         EXPIRED

4、2个账号都过期，于是修改密码

SYS@ orcl>alter user dbsnmp identified by oracle;

User altered.

SYS@ orcl>alter user sysman identified by oracle;

User altered.

 

5、再重新打开EM，能够正常使用了。在修改密码前我重新启动过数据库和EM
