OpenSolaris and WebSphere

As lot of you may have tried already installing/using WebSphere on OpenSolaris and may have ran into some issues during install so I thought I will cover some of those issues into this blog and will provide possible workaround.
The instruction below applies to WebSphere Application Server v6.1 and v7.0. I havn not  tested 6.0.X but I assume it will work fine. If not then let me know. 

OpenSolaris brings in lot of new feature details can be found at opensolris.org. If you don't want to commit a hard disk for OpenSolaris experience you can use VirtualBox and then install OpenSolaris inside VirtualBox. Once you figure out which route you want to take and how you want to install OpenSolaris then you need to grab installer for WebSphere and try installing it over. You will have following few options available to you to install:
Silent installation:

You will have to edit the template response file. After you make all the necessary changes if you try to install it will fail and if you check the log it will complain that this is not one of supported OS. The reason for this can be checked by the output of the command "uname -a" and as you can see from output it is being reported as "5.11".  So this is what you will have to add in your response file:
-OPT disableOSPrereqChecking="true"
Now try again and installation should complete without any error and you will get message about the Operating System version. Just ignore this message and start using.
Installing using the Installer GUI:
When you try to install using launchpad.sh it will come up but when it invokes the install command then it will fail complaining the installation cannot be started in GUI and suggest that you use "silent" installer. This error happens only with WAS v6.1 only WAS v7.0 is fine and you can install without any issues. If you want to get into details you can check the niflog  and you will understand that this is happening due to installshield issues. Googling for this will reveal that this is a known issue with lot of platform eg. AIX/Linux/Solaris and it has nothing to do with either the OS or WAS.
So we can use the java based installe by directly invoking the following command:
bash # java -jar setup.jar
This to succeed you must have java runtime in your path which is by default available in OpenSolaris. It will bring up the installer and as said earlier "Prerequisite Check" will fail and if you still continue everything will be installed right.

Just to make sure the "Install Verification Test" and you will observe all the test passing now you are good to go.
If you runinto any display issues it will be worth checking this blog.

Comments:

I workes just fine during the install, the problem is that it cannot run due to "java invalid argument" issue. Any ideas.
