Host System Memory

Looking for Zing? The Azul Zing Virtual Machine is now Azul Zulu Prime Builds of OpenJDK and part of Azul Platform Prime. Learn more.

A Linux system on which the Azul Zulu Prime Builds of OpenJDK (Azul Zulu Prime JVM) and Azul Zulu Prime System Tools (ZST) components are installed has a certain amount of physical memory (RAM). The Host System memory is used by all of the processes running on the machine. This includes memory used by the Linux kernel, Linux processes, and the Azul Zulu Prime JVM instances running Java applications. The operating system’s virtual memory system manages the RAM for use as System Linux memory. The ZST’s Zing Memory Module (ZMM) manages the RAM for use as System Zing Memory. The host system memory is used to satisfy requests made for memory when a process is launched and, as necessary, when the process is running.
