How to start and close OEMs in oracle10g

Starting with oracle10g, Oracle has greatly enhanced the OEM tools and fully demonstrated the EM tools on the server side.
In 10g, the client can invoke the powerful EM tool only by browser without having to install any Oracle client tools.

On the server side, you can start the EM tools console by using the following command:
Emctl Start Dbconsole

The following is the startup process:
[Oracle@danaly ~]$ emctl start Dbconsole
