How to avoid installation problems with java (jvm).

1. Problem

    The setup.bin hangs in the ‘Forking JAVA in launching installer’ stage.

     [ How to debug]

     – If you add the following to setup.bin, it shows that setup process stopped at the “Forking JAVA step”.

      1) ./setup.bin -Dlax.debug.all=true -Dlax.debug.level=3

     [LAX debugging] 

     /BI/gjang/prod/ebf25475>./setup.bin -Dlax.debug.all=true -Dlax.debug.level=3

     Preparing to install…

     …

     Launching installer…

     ========= VM Command Line ============================================

     options:   -DACTIVE=true

     CLASSPATH:/tmp/install.dir.18832/InstallerData:/tmp/install.dir.18832/InstallerData/installer.zip:

     ========= Forking JAVA ================================================

     ….

    …. <- The setup process stops.

2. Cause

    It seems to be a compatibility issue between OS env, patch  levels, tar version …. etc.

3. Possible solution

    When it hangs at “Forking JAVA”, you can force the installer to point to and use a functioning jvm (version 1.6 or higher) on the machine, by issuing the following command:

    % ./setup.bin LAX_VM “full_path_to_java_executable”

    ex) %  ./setup.bin LAX_VM /usr/bin/java
