Oracle Linux (or OEL for short) is a distribution of Red Hat Linux (RHEL) which includes additional packages, configurations and settings that are optimal for running Oracle products. In our test environments, this is frequently the operating system of choice, as it’s freely available, and very reliable for trying out various products related to the Oracle database.
One task that often becomes tedious is the update and installation of various packages, as there are often dependencies that come into play (at least, when using Linux’s various rpm commands). An alternative is to use the yum option, along with Oracle’s public repository which will handle all dependencies (including required patches and their minimum versions).
To get started, we must first have an installation of RHEL/OEL setup, in my case I’m using RHEL 5.5. We need to ensure that the server is connected to the internet, and can do so easily by trying to reach any valid host (for simplicity’s sake, I’m using Google’s page):
[root@rhelgrid yum.repos.d]# ping google.com
PING google.com (209.85.175.147) 56(84) bytes of data.
64 bytes from google.com (209.85.175.147): icmp_seq=1 ttl=56 time=5.11 ms

3 packets transmitted, 3 received, 0% packet loss, time 2001ms
rtt min/avg/max/mdev = 4.877/5.148/5.458/0.252 ms
Now that we know we’re connected, we need to go to the YUM configuration directory (located at /etc/yum.repos.d) and copy the public repository configuration file from Oracle’s public server (by using a wget command), as shown below:
[root@rhelgrid yum.repos.d]# wget http://public-yum.oracle.com/public-yum-el5.repo

2011-11-02 03:19:23 (268 MB/s) – `public-yum-el5.repo.1′ saved [2533/2533]
Next we need to edit the configuration file (public-yum-el5.repo) that we downloaded earlier, and ensure that the correct version of the repository is enabled (based on whether we are using OEL or RHEL, and the current update number we’re on):
[el5_u5_base]
name=Enterprise Linux $releasever U5 – $basearch – base
baseurl=http://public-yum.oracle.com/repo/EnterpriseLinux/EL5/5/base/$basearch/
gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
gpgcheck=1
enabled=1
As seen above, I’m enabling the repository for RHEL 5, update 5 (or RHEL 5.5). Now all that remains is to ensure that we are able to list all the packages included in the repository, and install what we require (I’m going to install samba-winbind to test out some DNS server configurations):
[root@rhelgrid yum.repos.d]# yum list | grep win

So there we have it, the public YUM repository was able to list everything that I needed, as well as identify 2 packages that were pre-requisites for winbind, download and install all of them once I confirmed the operation
