Oracle Enterprise Manager and
the ODA
Oracle Enterprise Manager Cloud Control 12c
(referred to hereafter as
EM12c
) is the latest version of Oracle
Corporation's end-to-end management tool for both Oracle and non-Oracle technology. Previously known as Oracle
Enterprise Manager (OEM) or Oracle Enterprise Manager Grid Control, the tool has been around for quite some time
now. The 12c release, though, is a landmark version that makes huge advances in terms of both the breadth and depth
of its functionality. In many ways, this release has moved Enterprise Manager from being a database administrator's
monitoring tool, to a tool that can be used to manage your entire Oracle data center.
Before you can understand how EM12c can be used in an ODA environment, you really need to have an
understanding of the basic architecture of EM12c, so let's start by providing you with an introduction to the basic
architecture of EM12c.
Architecture Overview
From an architectural perspective, EM12c is composed of five main parts:
•
The Cloud Control console
•
Oracle Management agents
•
The Oracle Management Service
•
The Oracle Management Repository
•
Plug-ins
Let's look at each of these in more detail.

A discussion of the licensing for EM12c is beyond the scope of this topic. (An entire licensing document is
available in the Enterprise Manager documentation at
http://docs.oracle.com/cd/E24628_01/license.121/e24474/
toc.htm
.
) However, it's worth noting that, in general, most of the basic functionality described here carries a
restricted-use license and therefore is free. This restricted-use license refers specifically to Enterprise Manager, however,
and many add-on options do come with license costs. Refer to the licensing documentation for full details.
