When I run yum update i get the following error and no packages are updated.
Appreciate any help.

What is enabled in your yum repo?

I recomend that you use the atomic yum repo for new software build for rh9. You can find some file here:

Below all the files are all the different repos this guy has setup. Most of them are for plesk servers, but the ones that don't say "psa" in them you can probably use just fine.
