如何在CentOS中扩展Java虚拟内存？

Question

as I wrote on the title, I want to extend Virtual Memory while performing my java code. currently, I'm writing a code for word Analyzer. In eclipse if there are 1000 number of inputs then it gives 1000 fine outputs. however when I run it from a server, it gives 80% outputs and 20% for null. after that I asked this problem to someone I know and he said it is because of small size of Virtual Memory in the server.

I normally run the java program with .sh file and content of the .sh file is written as below.

export JAVA_HOME="usr/lib/jvm/java-1.6.0-openjdk.x86_64"
PATH=$PATH:JAVA_HOME/jre/bin
export JAVA_HOME

java -cp /home/account/count_con.jar countConversation.countCon_Starter &

and then type "bash .sh file".

Please give me your kind advice for how to run java code with extra Virtual memory size in server(OS:CentOS).

Thank you

after java command set the flag -Xmx size m

FYI

Xms is initial Java heap size

Xmx is maximum Java heap size

Xss is java thread stack size
