Oracle EM 启动出错

错误信息：

[oracle@VMRHEL5 ~]$ emctl start dbconsole

TZ set to PRC

OC4J Configuration issue. /u01/app/oracle/product/10.2/db_1/oc4j/j2ee/OC4J_DBConsole_localhost.localdomain_orcl not found.

解决办法：

方法一（推荐）： 使用dbca对数据库重新配置下即可

方法二：手动配置

参考：http://www.stefanocislaghi.eu/2009/12/28/unable-to-run-dbconsole-oc4j-configuration-issue/

This is due to a misconfiguration of dbconsole during database setup. The fastest solution is usually to recreate repository and configuration.

First, deconfigure dbconsole:
