Maybe. Most 32-bit JVMs can't actually give you 3GB of heap space.
You'll probably be limited to somewhere between 1.5 - 2.0GB. If you have
a 64-bit processor and OS, go with a 64-bit JVM and then you can get
/lots/ of memory.

I'm not entirely sure what you mean, here. Could you try to ask this
question in a different way?

That ought to give you a 1.5GB fixed (no more, no less) heap.
