從oracle10g開始，oracle極大的增強了oem工具，并通過服務器端進行em工具全面展現。
在10g中，客戶端可以不必安裝任何oracle客戶端工具，僅憑瀏覽器就可以調用強大的em工具。

在server端，可以通過如下命令啟動em工具控制臺:
emctl start dbconsole

以下是啟動過程:
[[email protected] ~]$ emctl start dbconsole
tz set to prc
oracle enterprise manager 10g database control release 10.2.0.1.0

starting oracle enterprise manager 10g database control .......................... started.
------------------------------------------------------------------
logs are generated in directory /opt/oracle/product/10.2.0/danaly.hurrray.com.cn_danaly/sysman/log

啟動之后我們就可以通過在瀏覽器端輸入以下url訪問:
http://danaly.hurrray.com.cn:1158/em/

同樣停止oem可以輸入如下命令:
emctl stop dbconsole

以下是停止過程:
[[email protected] ~]$ emctl stop dbconsole
tz set to prc
oracle enterprise manager 10g database control release 10.2.0.1.0

http://danaly.hurrray.com.cn:1158/em/console/aboutapplication
stopping oracle enterprise manager 10g database control ......  stopped.

也可以直接鍵入emctl查看emctl支持的選項:

[[email protected] ~]$ emctl
tz set to prc
oracle enterprise manager 10g database control release 10.2.0.1.0
