Get JVM to grow memory demand as needed up to size of VM limit?

Question

We ship a Java application whose memory demand can vary quite a lot depending on the size of the data it is processing. If you don\'t set the max VM (virtual memory) size

Answer 1

I read through the threads but didn't see anything which indicated that the application had undergone some sort of profiling. Normally I'd profile the apps under certain conditions to find hot spots in performance or memory usage. There's probably things that could be improved in most cases.

If you could establish the limits and understand the behavior of the application you could be in a position to better tell your customers what they can or cannot do with the application thereby reducing the amount of support calls and giving you a better idea of what minimum or maximum heap size to ship the product with.
