创建完毕后直接emctl start dbconsole就可以了

在执行命令时可能会出现如下错误:

 [oracle@ocm ~]$ emca -repos drop ­

实际上是可能环境变量配置的问题,最简单的解决办法:

cd /$ORACLE_HOME/bin

在此目录下执行相关的命令就可以解决。

打开EM的时候,页面显示如下错误:

503 Service Unavailable
Service is not initialized correctly. The Em Key is not configured properly. Run "emctl status emkey" for more details.

初步判断是因为emkey文件失效,可能是因为之前导入数据的时候导致的此错误。

按照提示做如下操作:

[oracle@ocm ~]$ emctl status emkey
Oracle Enterprise Manager 11g Database Control Release 11.2.0.3.0 
Copyright (c) 1996, 2011 Oracle Corporation.  All rights reserved.
Please enter repository password: 

The Em Key is not configured properly or is corrupted in the file system and does not exist in the Management Repository. To correct the problem:
1) Copy the emkey.ora file from another OMS or backup machine to the OH/sysman/config directory.
2) Configure the emkey.ora file by running "emctl config emkey -emkeyfile <emkey.ora file location>".

按照2)的方法做,实际上是需要有备份存在

[oracle@ocm bin]$ emctl config emkey -emkeyfile /u01/app/oracle/product/11.2/ocm.oracle.com_ocm/sysman/config/emkey.ora -force -sysman_pwd oracle
Oracle Enterprise Manager 11g Database Control Release 11.2.0.3.0 
Copyright (c) 1996, 2011 Oracle Corporation.  All rights reserved.

The Em Key could not be configured. /u01/app/oracle/product/11.2/ocm.oracle.com_ocm/sysman/config/emkey.ora is corrupted or contains an invalid Em Key.

还有一个方法就是重建EM,方法如之前所示。
