Architecture
OEM 10g is installed by default when you install the 10g software. Conceptually, it differs from previous versions in that instead of being a client-installed tool, it's actually an HTTP server (called DB Console) sitting on the database server itself. (See Figure 1.) You can use any browser to see the EM interface.

The port number for DB Console is found in $ORACLE_HOME/install/portlist.ini. Here is an example of a file; ports in your case may be different.
Ultra Search HTTP port number = 5620
iSQL*Plus HTTP port number = 5560
Enterprise Manager Agent Port =
Enterprise Manager Console HTTP Port (starz10) = 5500
Enterprise Manager Agent Port (starz10) = 1830
From this file we know that the Agent for the database starz10 listens on the port 1830 and the EM console listens on 5500. We can invoke the EM logon screen by entering the following URL:
http://starz/em/console/logon/logon
This URL brings up a logon screen where you can log on as a DBA user. For our example, we will log in as SYS.
