Installation problem oracle 11g R2 on oracle enterprise linux 5 update 5

Question

hello support,
i've installation problems with oracle 11g R2 on oracle enterprise linux 5 update 5. In the section "ORACLE Net-Konfigurationsassisten" the failure "[INS-20802] Oracle NET-Konfigurationsassistent not success". What's wrong? I've followed the instructions on http://www.oracle.com/technology/pub/articles/smiley-11gr1-install.html
I've heard the problem can occur with problems in /etc/hosts? My /etc/hosts is configured:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1          oracle localhost.localdomain localhost
::1          localhost6.localdomain6 localhost6
is this ok? what can I do to bring the database-installation to success?
Thank's for help ;-)

Answer 1

Here I paste you the configuration of my latest linux box which has a similar environment like yours.
# hostname
vmrhel6032.quist.ch
# domainname
(none)
# cat /etc/hosts
192.168.1.205 vmrhel6032 vmrhel6032.quist.ch
127.0.0.1     localhost  localhost.localdomain localhost4 localhost4.localdomain4
::1           localhost  localhost.localdomain localhost6 localhost6.localdomain6
# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=vmrhel6032.quist.ch
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
HWADDR=00:0C:29:6A:98:70
ONBOOT=yes
NETWORK=192.168.1.0
NETMASK=255.255.255.0
IPADDR=192.168.1.205
#Thanks to your post I noted that the hostname consist already of my domain entry. Try your configuration first without domain entry. It should look like:
# hostname
vmrhel6032
# domainname
(none)
# cat /etc/hosts
192.168.1.205 vmrhel6032
127.0.0.1     localhost  localhost.localdomain localhost4 localhost4.localdomain4
::1           localhost  localhost.localdomain localhost6 localhost6.localdomain6
# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=vmrhel6032
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
HWADDR=00:0C:29:6A:98:70
ONBOOT=yes
NETWORK=192.168.1.0
NETMASK=255.255.255.0
IPADDR=192.168.1.205
#Otherwise use the first example and don't forget to restart your server resp. the network service. ;)
