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

There is two options in the virtual machine arguments that can be used : -Xms to set the memory size at startup and -Xmx to set the maximum memory size...

You can set a low startup memory and a big maximum one, so the VM will allocate new memory only if needed.
