If you cant remote connect to your database or to VNC it may be due to firewall restrictions.
1) Start VNC server and check which port its connected on by running: netstat -tlnp
2) Edit the iptables file to allow that port.
$ vim /etc/sysconfig/iptables
3) add this line:
RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport xxxx -j ACCEPT
BEFORE
RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
Replace the xxxx with the port number you found in step 1.
4) Restart your iptables
$ service iptables restart
If you can't connect to database via SQL developer (ie you are getting a network adaptor error) then try this step as well to allow outside connection.
5) Start VNC Server
$ service vncserver restart
