现象：

Windows 不能在 本地计算机 启动 OracleDBConsoleorcl。有关更多信息，查阅系统事件日志。如果这是非 Microsoft 服务，请与服务厂商联系，并参考特定服务错误代码 2。

系统事件日志 报错误"Agent process exited abnormally during initialization."

出现情况：原来正常，IP地址变了后就不能启动，　　

我的解决步骤如下：

1、开始-》运行cmd

2、执行 emctl start dbconsole

C:Documents and Settingsxcl>emctl start dbconsole

Environment variable ORACLE_SID not defined. Please define it.

提示：环境变量 ORACLE_SID 未定义，请定义。

3、设置 ORACLE_SID =ORCL (orcl是我的实例名，也是服务名)

C:Documents and Settingsxcl>set oracle_sid=orcl

4、再次执行emctl start dbconsole

C:Documents and Settingsxcl>emctl start dbconsole
