You can increase to 2GB on a 32 bit system. If you're on a 64 bit system you can go higher. No need to worry if you've chosen incorrectly, if you ask for 5g on a 32 bit system java will complain about an invalid value and quit.

java -Xmx6g myprogram

You can get a full list (or a nearly full list, anyway) by typing java -X.
