// Download and replace yum repository file with the new one! # cd /etc/yum.repos.d # rm public-yum-ol6.repo # export http_proxy=proxy.acme.com:80   (optional) # wget http://public-yum.oracle.com/public-yum-ol6.repo # nano public-yum-ol6.repo // find section [ol6_UEKR3_latest] and set Enabled=1 # yum update # reboot

That’s it. Don’t forget to set Enabled=1 in ol6_UEKR3 section, unless you don’t want to upgrade UEK2 kernel to version UEK3.
