A couple of days ago, I got request from one of the user for oracle client installation on his new application server. When I started client installtion, I got following error:

A screeshot with just a message : <hostname>:<hostname> as given below:

After searching in error logs for all possible causes of this error, I got following information:

Install log:

After searching on metalink I found this note: During 11.2.0.3 Install Get Pop-Up Error – <Hostname>:<Hostname> (Doc ID 1396516.1)

Following are the possible causes of this issue:

1. The hostname of the server is not defined in /etc/hosts.
2. This error can also appear if the hostname defined in /etc/hosts is incorrect and is not resolvable.

In my case it was 2nd one. After correcting /etc/hosts with proper entries, issue got resolved.

Hope so u will find this post very useful 🙂

Cheers
