Oracle WebTier (11g) Installation hangs

Oracle WebTier provides components like HTTP Server and WebCache which help in routing http requests from external users to the application server. It provides lot of flexibility to Oracle SOA Suite installations by having security, clustering, load balancing features built into it.

I have been using Oracle Webtier for most of my SOA 11g Cluster installations and the installation/configuration has been pretty straight forward. For a WebTier 11.1.1.4 installation basically install the 11.1.1.2 via Installer and apply the 11.1.1.4 patchset on top of it. This is followed by some post install configurations incase you want to setup cluster i.e adding load balancer (VIP) url in httpd.conf and mod_wls_ohs.conf files.

Tried to capture a few installation screenshots below:

Choose the installation type. Default is to Install and Configure in one shot.

Specify the admin server fully qualified domain host name. Eg. abc.mycompany.com

This is where the issue happened. Usually in all my previous installations the post install config step below was successful. But somehow on this specific server it was always getting stuck at 0% and I couldn't find any errors in the install log files for this weird behaviour.

After couple of attempts I decided to take an alternate route of Installing Webtier only (Choose the option Install Software- Do Not Configure) and configuring it in a later step by running (WT_HOME/bin/config.sh). This approach worked and I was able to continue with my installation after scratching my head for few hours.
