Hi Aydin,
Please see the debug output below. Looks like we have another problem at this time, the "getupdates.oracle.com" can't be resolved. I have tried to access it from two different networks but no luck.
This really seems to point at a problem with the DNS resolution setup on your site. What do you get from "nslookup getupdates.oracle.com" or "getent hosts getupdates.oracle.com"? Are /etc/resolv.conf and /etc/nsswitch.conf configured correctly?
Martin.
