If you encountered below error while running RCU then it could be either because you have recently changed the network settings like ip, domain name etc of your machine or the network setup of the machine is not complete.
2010-11-09 15:14:47,750 ERROR [create_gui] com.bea.plateng.wizard.domain.gui.tasks.DomainCreationGUITask - Generation Error!!
Traceback (innermost last):
File "<iostream>", line 35, in ?
File "/mymwhome/wlserver_10.3/common/wlst/modules/jython-modules.jar/Lib/socket$py.class", line 338, in gethostname
gaierror: (20001, 'getaddrinfo failed')
...
$ ping <hostname>
$ ping <ip address>
check DNS name resolution
$ nslookup <hostname>
If the server cannot resolve its own ip or hostname then modify /etc/hosts file with entry
<ip address> hostname.domain hostname
This should solve the error. Rerun the RCU and it should go smooth.

To resolve this issue first check whether the machine can resolve its own ip and hostname -
$ ping <hostname>
$ ping <ip address>
check DNS name resolution
$ nslookup <hostname>
If the server cannot resolve its own ip or hostname then modify /etc/hosts file with entry
<ip address> hostname.domain hostname
This should solve the error. Rerun the RCU and it should go smooth.
