  1. I have faced a problem like Mobilefirst server not starting until i edit the JVM.options (-DOS.name = Windows 8) in the eclipse.

  2. I need to do the above step manually whenever i create a new workspace

  3. Is there any other way to completely resolve this problem.

Note : I am using Windows 8.1

Try adding that option to the eclipse.ini file located in your Eclipse installation folder, instead of in the JVM.options of your workspace.
