RE: Setting default JDK and level

It's been awhile but I think if you go into:

/QIBM/UserData/Java400/SystemDefault.Properties

You'll see something like this:

************Beginning of data**************
java.version=1.4
java.awt.headless=true
************End of Data********************

And you can change the java.version string that will do it. That will be
global for everyone since it's a systemdefault. You'll need to make sure you
have the option for each version of the JDK installed in order to use it.
I'm not sure what will happen if you set it to a version number that isn't
installed, but its probably not good! :)

You can then run RUNJVA CLASS(*VERSION) from a command line to see what the
JVM version is, mine shows JVM V5R1M0 JDK 1.4.2 when its set to 1.4, and
when i set it to 1.3 it comes up JVM V5R1M0 JDK 1.3.1.

Subject: Setting default JDK and level


Our development system starts the JVM at JDK 6 level 1.6. Our production
machine starts JDK 5. Everything is identical installation wise, so the
production machine is capable of running JDK 6. Does anyone know where
this is set at? It seems to be JAVA_HOME variable, but where is that set
at?


For example, in the job log I see:
Development:
Cause . . . . . : JAVA_HOME environment variable is
/QOpenSys/QIBM/ProdData/JavaVM/jdk60/32bit

Production:
Cause . . . . . : JAVA_HOME environment variable is
/QOpenSys/QIBM/ProdData/JavaVM/jdk50/32bit
