How to increase java heapsize for ubuntu system?

Hello I am running a toolbox written in java from python. I am using Ubuntu. I launch the toolbox using jvm from my python file.

However when I increase my data size the program crashes with the following error message "java.lang.OutOfMemoryErrorPyRaisable: java.lang.OutOfMemoryError: Java heap space"

I went through some posts here on stack overflow for similar questions and I tried their suggestions such as going to command line and typing $ export _JAVA_OPTIONS=-Xmx4096m followed by $ java -XshowSettings:vm However I get the following Max. Heap Size (Estimated): 512.00M Ergonomics Machine Class: client Using VM: IBM J9 VM ................(there is a lot more here)

Basically it doesnt seem to increase my heap size and the error persists. How do I increase my heapsize?

Thank You!

Instead of export _JAVA_OPTIONS=-Xmx4096m, try using export IBM_JAVA_OPTIONS=-Xmx4096m.
