I'm not quite sure what you are asking, but...
If you want to set up your urpmi sources, check out the Easy Urpmi site linked in my sig.
If you already have your sources set up, and want to update their statuses, then you can either 1) run the command "urpmi.update -all", or 2) click the "Update Media" button in rpmdrake.
If you mean something else, please try to explain better (understanding that English is not your native language).
