You have Oracle Enterprise Manager for a single database called Database Control or DbControl.
Oracle Enterprise Manager for multiple databases is called GridControl.
The interface of GridControl and Database Control is a Webserver (actually Grid Control comes with Oracle Application Server) on the database server, so there is NO client install at all. Just open the appropiate URL on any browser and you can logon to Grid Control.

The equivalent of changing parameters through Grid Control would be issuing Alter system set ... = scope=both in sql*plus or isql*plus (sqlplus via a browser).

So there is no such thing as a small install, and 2.5 Gb is actually not much nowadays.

(Next question expected: How do I install Grid Control?)
