Oops, I meant hundreds of _gigabytes_ (just a slight miscalculation :-). With the 32-bit Sun JVM, you're not going to get much more than 1.2 GB you're at now, primarily due to the contiguous heap requirement and the use of signed 32-bit integers within the HotSpot heap manager. To take advantage of the 64-bit platforms, you'll need to install a true 64-bit JVM, which is a separate download from the normal JRE/JDK. With that, you should be able to use pretty much all of the RAM, minus the system overhead. The key issue is insuring that the 64-bit Debian provides a decent amount of virtual space for each process. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
