Azul Zing® introduces a new Elastic Heap feature (aka Best Effort Elasticity or BEE) that allows you to:
-Xmxmemory parameter when launching your Java virtual machine
-Xmxlow but make sure that your Java virtual machine can handle peak loads that require a higher amount of memory
The Elastic Heap feature satisfies the above scenarios by providing flexibility to borrow memory above the value specified by
-Xmx from a common memory allocation pool without an impact on your system performance.
This alleviates the need to configure each virtual machine with a large amount of memory space thereby reducing the total RAM requirement.
The borrowed memory is returned as soon as the garbage collector detects that the memory pressure is back to normal, letting other virtual machines on the same operating system instance access the memory.
To enable the Elastic Heap feature, use the following option:
