WebSphere Application Server and Red Hat Enterprise Linux

In this post, I briefly mention how I was able, with assistance from an IBM Technote, overcome an issue with the installation of IBM WebSphere Application Server v7 on Red Hat Enterprise Linux 6.3.

In order to help a  colleague, I went through the process of installing WAS Network Deployment v7 on RHEL 6.3 ( x86-64 ) earlier today. From this, I created a set of slides that showed each step of the installation, and also made reference to the pre-requisites that I put in place beforehand.

I did see an issue with the installation, relating to the Launchpad application that one can use to commence the installation ( assuming that one doesn't go down the silent/response-file driven installation ).

When I attempted to start the Launchpad, I was presented with this message: -

Unable to find supported browser.
The launchpad cannot start. This error typically occurs when a supported browser cannot be found.

As ever, I Google'd this, and immediately found this IBM Technote: -


which said, in part: -

...
To get the Launchpad working in older versions, you need to edit the <install_root>/launchpad/browser.sh command so that it contains the following string in the supportedFirefoxVersion case statement:

*Firefox\ [1-9][0-9].*) return 0;;

The function should then look like this:

supportedFirefoxVersion()
{
       case "$*" in
               *Firefox\ [1-9].*) return 0;;
               *Firefox/[1-9].*) return 0;;
               *Firefox\ [1-9][0-9].*) return 0;;

 ...

As one might imagine, this worked a treat.

So, as a favour (!), here's the WHOLE script, with the amendment in place: -

LaunchPadDefaultBrowser=$BROWSER; export LaunchPadDefaultBrowser
export whichBrowser
if [ "$LaunchPadTest" ]; then
    echo $LaunchPadBrowserPath
    echo $BROWSER
fi

I also saw the same issue after the installation, from the First Steps application. Again, this was a simple amendment ( identical to the above ) to a different script - fbrowser.sh - which is, again, referenced in another IBM Technote here: -


Hope this helps.
