Checking the Network Setup


Configuring Name Resolution
When you run Oracle Universal Installer, an error may occur if name resolution is not set up. To avoid this error, before you begin installation, you must ensure that host names are resolved only through the

/etc/hosts

To ensure that host names are resolved only through the /etc/hosts file:

Verify that the /etc/hosts file is used for name resolution. You can do this by checking the hosts file entry in the nsswitch.conf file as follows:

# cat /etc/nsswitch.conf grep hosts

The output of this command should contain an entry for files.

Verify that the host name has been set by using the hostname command as follows:

# hostname

The output of this command should be similar to the following:myhost.mycomputer.com
Verify that the domain name has not been set dynamically by using the domainname command as follows:

# domainname

This command should not return any results.
Verify that the hosts file contains the fully qualified host name by using the following command:

# cat /etc/hosts grep `eval hostname`

The output of this command should contain an entry for the fully qualified host name and for localhost.

For example:192.168.100.16 myhost.us.mycompany.com myhost
127.0.0.1 localhost localhost.localdomain
