You might want to look into memory grids like:

We use Coherence to run 3 JVMs on 1 machine, each process is using 1 Gb of the RAM.

There are a number of solutions.

  • Use a larger heap size (possibly 64-bit JVM)
  • Use less heap and more off heap memory. Off heap memory can scale into the TB.
  • Split the JVM into multiple processes. This is easier for some applications than others. I tend to avoid this as my applications can't be split easily.
