Changing Java parameters

Changing Java parameters

Hi,
I would like to know, how you administrator can manage Java environment included in Desktop Central server engine? I understand that Java environment included in 10.0.515 is 1.8.0.192 x64, but what I can see that Java engine uses up to 2,5GB of RAM and can't go futher. Is there a way to change Java RAM usage to increase that limit?

Thanks,
