Memory-addressing constraints

Recommended Posts

I have an application that currently uses 48 gig of RAM - and the plan is to load it to a box with 192. I'm assuming that the current 32bit compile won't support that. Is this correct?

Correct.

Address space for 32-bit applications is limited to 4 Gb. In practice, 32-bit Java applications can use up to 1.2-3.5 Gb of memory for Java heap depending on OS and system configuration.

64-bit version of Excelsior JET is not available yet, but it is actively developed right now. It will allow Java heaps > 4Gb.
