oracle 11g 修改sysman和dbsnmp用户密码后没法使用em

实验背景：

现有一台配置了EM的oracle数据库，数据库版本11.2.0.4，修改sysman和dbsnmp用户密码后重启em，发现em不可用。如图：

sysman和dbsnmp用户状态，发现sysman用户状态为锁住

 

 

 

正确修改sysman和dbsnmp用户密码的方法以下：

 

一、关闭em

[oracle@dbserver ~]$ emctl stop dbconsole

Oracle Enterprise Manager 11g DatabaseControl Release 11.2.0.4.0

Copyright (c) 1996, 2013 OracleCorporation. All rights reserved.

Stopping Oracle Enterprise Manager 11gDatabase Control ...

... Stopped.

[oracle@dbserver ~]$

 

二、修改sysman的密码而且给sysman用户解锁

 

三、执行emctl setpasswd dbconsole命令修改密码

[oracle@dbserver ~]$ emctl setpasswddbconsole

Oracle Enterprise Manager 11g DatabaseControl Release 11.2.0.4.0

Please enter new repository password:

Repository password successfully updated.

 

[oracle@dbserver ~]$

 

四、修改dbsnmp用户的口令

[oracle@dbserver emd]$ pwd

/u01/app/oracle/product/11.2.0/db_1/dbserver_sztech1/sysman/emd

[oracle@dbserver emd]$

[oracle@dbserver emd]$ cp targets.xmltargets.xml.bak

[oracle@dbserver emd]$vi targets.xml

修改下面内容

<Property NAME="password"VALUE="oracle123" ENCRYPTED="FALSE"/>

 

五、从新启动em

[oracle@dbserver emd]$ emctl startdbconsole

Oracle Enterprise Manager 11g DatabaseControl Release 11.2.0.4.0

Copyright (c) 1996, 2013 OracleCorporation. All rights reserved.

Starting Oracle Enterprise Manager 11gDatabase Control ..... started.

 

Logs are generated in directory/u01/app/oracle/product/11.2.0/db_1/dbserver_sztech1/sysman/log

[oracle@dbserver emd]$

 

六、验证

能够看到，em能够正常使用
