So today I tried to install the Oracle Preinstall RPM on a freshly installed Oracle Linux 7 machine. However, when I executed yum search rdbms the preinstall package was nowhere to be seen!

It turns out that we need to enable the Oracle Linux 7 “addons” repository in order to find the package. Swiss blogger Martin Berger put me on the right track.

To enable the repository, open the file /etc/yum.repos.d/public-yum-ol7.repo and find the following repository entry:

[ol7_addons]
name=Oracle Linux $releasever Add ons ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL7/addons/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=0

Then, enable the “ol7_addons” repository, by setting the value of “enabled” to 1:

enabled=1

After that, execute yum update and install the package:

# yum update
# yum install oracle-rdbms-server-12cR1-preinstall

Now you’ll be able to continue with the installation (and execute the -verify executable).
