我已经在 Oracle linux 7.2 上安装了 oracle 数据库 11gR2。但是，oracle 企业管理器无法正常工作。我试图弄清楚我们出了什么问题，经过长时间的搜索，我发现了一个建议我应该重新配置 EM 的博客。使用以下命令
#emca -config dbcontrol db -repos recreate
此命令启动良好，但在保护数据库控制台时失败，并出现以下错误。
保护 Database Control 时出错，Database Control 已在非安全模式下启动。要保护数据库控制，请执行以下命令：
1) Set the environment variable ORACLE_SID to orcl
2) /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl stop dbconsole
3) /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl config emkey -repos
4) -sysman_pwd < Password for SYSMAN user /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl secure dbconsole
-sysman_pwd < Password for SYSMAN user >
5) /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl start dbconsole
To secure Em Key, run /u01/app/oracle/product/11.2.0.4/db_1/bin/emctl config emkey -remove_from_repos -sysman_pwd < Password for SYSMAN user >

问题在于执行上面的步骤（4）。每次我运行第 4 步的命令时，我都会收到以下错误
*[04-08-2016 12:00:39] USERINFO ::DBCONSOLE already stopped... Done.
[04-08-2016 12:00:39] USERINFO ::Failed to stop agent...*
无法识别命令emctl stop agent以及emctl start agent
下面是一些日志文件的内容

我的代理版本是 10.2.0.4.0
我的数据库控制版本是 11.2.0.1.0
我不能停止也不能启动代理。这使我无法继续在互联网上获得任何帮助，因为它需要启动和停止代理。
当我运行命令*#emctl status agent*时，我得到以下输出
*Oracle Enterprise manager 11g DB Control 版本 11.2.0.1.0
版权所有 (C) 1996、2009 甲骨文公司。保留所有权利。*
请我在过去的 5 天里一直在尝试解决这个问题，但是当有任何涉及启动或停止代理的步骤时，我总是被卡住。所以我客人我的主要问题是代理。
