  2. Download and copy the appropriate yum configuration file in place, by running the following commands as root:

    Oracle Linux 4, Update 6 or Newer

    # cd /etc/yum.repos.d # mv Oracle-Base.repo Oracle-Base.repo.disabled # wget http://public-yum.oracle.com/public-yum-el4.repo 

    Oracle Linux 5

    # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-el5.repo

    Oracle VM 2

    # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-ovm2.repo 
  3. Enable the appropriate repository by editing the yum configuration file

    • Open the yum configuration file in a text editor
    • Locate the section in the file for the repository you plan to update from, e.g. [el4_u6_base]
    • Change enabled=0 to enabled=1
  4. Begin using yum, for example:

    yum list

    yum install firefox
