The Cloud Control Console
The
Cloud Control console
provides the user interface that you use to access, monitor, and administer your computing
environment. The console is accessed via a web browser, thus allowing you to access the central console from any
location. You can customize the EM12c console much more than in previous releases, allowing you the following
options:
•
Choosing your home page from various predefined pages (or indeed setting any page you
want to be your personal home page)
•
Moving regions around on a target home page
•
Adding regions that might be of more interest to you than the defaults
•
Deleting regions that aren't of interest to you
The graphical user interface (GUI) provides a history of the most recent targets you have visited (the standard
browser history is also available). In addition, you can mark pages as favorites and have them appear in a favorites list
on the new menu-driven interface. Figure
1-1
shows an example of the default home page.

Oracle Management Agents
An
Oracle Management Agent
(usually referred to as simply an
agent
or abbreviated to
OMA
) is generally installed
on each host that is monitored in your computing environment. (EM12c also introduces the capability to manage
environments remotely in some cases.) These agents are deployed from the console (see Figure
1-2
), and then
monitor all the targets that have been discovered by the agents. They are used to control blackouts on those targets,
execute jobs, collect metrics, and so forth, and in turn provide details such as availability, metrics, and job statuses
back to the Oracle Management Service.
