Tip

Installing Management Repository
In this section, you'll download and install Oracle Database 11gR2 on the server named repositorydb.testdomain.com .
It's possible to use one of the certified databases: 11.2.0.3, 11.2.0.2, 11.2.0.1, 11.1.0.7, or 10.2.0.5. If you already
have a database server for the repository database, you can skip to the installation of Oracle EM12c.

■ you can find an up-to-date list of certified databases for enterprise manager Cloud Control on my oracle support:

(raC) database for high availability.

Tip

Using the Oracle-Validated RPM Package and YUM
In order to install Oracle Database 11gR2 on Oracle Linux, your system needs to meet a few prerequisites. Using the
oracle-validated RPM package, you can complete most of the preinstallation configuration tasks including creating
a user and groups. Using this package is the recommended way to install all the Oracle prerequisites on Oracle Linux.
You can download the RPM package from the Oracle web site, or you can use the YUM package manager. Oracle
provides a free public yum server that you can use even if you don't buy support from Oracle.
To use the Oracle public yum server, you first need to download and copy the appropriate yum configuration file
in place, by running the following commands as ROOT :

• Oracle Linux 4, update 6 or newer

[root@repositorydb ~]# cd /etc/yum.repos.d
[root@repositorydb ~]# mv Oracle-Base.repo Oracle-Base.repo.disabled
[root@repositorydb ~]# wget http://public-yum.oracle.com/public-yum-el4.repo

• Oracle Linux 5

[root@repositorydb ~]# cd /etc/yum.repos.d
[root@repositorydb ~]# wget http://public-yum.oracle.com/public-yum-el5.repo

• Oracle Linux 6

[root@repositorydb ~]# cd /etc/yum.repos.d
[root@repositorydb ~]# wget http://public-yum.oracle.com/public-yum-ol6.repo
Open the yum public-yum*.repo configuration file in a text editor. Locate the section in the file for the repository
you plan to update from—for instance, [el5_base] —and change enabled=0 to enabled=1 .
Save the file and start using yum:

[root@repositorydb ~]# yum install oracle-validated
