现象：

使用top命令一查，发现上千个进程在运行，cpu利用率非常高。

再使用ps –ef | grep –c oracle一统计，有831个关于oracle的进程，这其中，有大量的perl进程：

/opt/oracle/product/10.2.0/db_1/sysman/admin/scripts/db/dbresp.pl

原因：

根据metalink Doc ID: 764140.1描述：The Response metric is making a timed out then the Agent starts other process to take the Response metric. The process to kill the PID taking the Response metric is failing increasing the process running dbresp.pl。

解决方法：

同样根据根据metalink Doc ID: 764140.1：

To implement the solution, please execute the following steps:
1. Stop DBConsole
emctl stop dbconsole

2. Kill any running process.
ps -ef | grep /opt/app/oracle/_
Kill any returned process.

3. Follow fix
Note.361612.1 Ext/Mod Problem Performance Agent High CPU Consumption Gen

4. Start DB Console
emctl start dbconsole
