Installation and Security Framework
and EM12c Release 4

Now that you understand the Enterprise Manager architecture, you may want to understand more-advanced
installation methods for the Oracle Management Service (OMS) host or for a remote installation. You'll also want to
be up to date on the latest verbs that come into play with 12.1.0.4, also known as EM12c Release 4, which is all covered
in this chapter.

EM CLI and WebLogic Installation
Enterprise Manager runs as a domain on a WebLogic server (WLS). The cloud life-cycle solution couldn't exist without
the middle-tier architecture provided by WebLogic. WLS handles the business logic along with communicating with
web services and other remote processing to ensure front-end transactions are completed from beginning to end.
There was a time when the OMS required a separate installation of the WLS. Although it's currently an automated
step in the installation of EM12c, comprehending how to perform this manually is valuable to the administrator,
especially going forward when administering and managing the environment.
The WebLogic server must be made available to and synchronized with the Enterprise Manager Command-Line
Interface (EM CLI) in order to offer the latest plug-ins, management packs, and full access to the Enterprise Manager
Cloud environment.

Requirements
In order to understand the requirements before the EM CLI installation on your OMS proceeds, ensure that the
WebLogic Domain Provisioning Profile is created in such a way that the software library has the Middleware Home
that belongs to the domain archived and stored as part of the WebLogic domain.

Creating the WebLogic Domain Provisioning Profile
There are three components that make up the provisioning profile:

• a middleware home

• the binaries used by the WebLogic server components

• the domain configuration for the provisioning profile
