Oracle Enterprise Manager (OEM) has the following components:
. Management Server (OMS): Middle tier server that handles
communication with the intelligent agents. The OEM Console connects
to the management server to monitor and configure the Oracle
enterprise.
. Console: This is a graphical interface from where one can schedule
jobs, events, and monitor the database. The console can be opened
from a Windows workstation, Unix XTerm (oemapp command) or Web
browser session (oem_webstage).
. Intelligent Agent (OIA): The OIA runs on the target database and
takes care of the execution of jobs and events scheduled through the
Console.
