How to increase java heap space by using .bashrc file in linux server?

Thanks in advance.

Answer 1

Do as follows:

export _JAVA_OPTIONS="-Xmx10g"

To be sure that it is working, whenever you run a java file, it should output: Picked up _JAVA_OPTIONS: -Xmx10g

Answer 2

I'm sure this has been answered before, but something like

export JAVA_OPTS=-Xmx1024m

Hope that helps.
