Using vFabric Elastic Memory for Java

Revised July 31, 2012.

Using vFabric Elastic Memory for Java describes how to set up, monitor, and manage VMware® vFabric™ Elastic Memory for Java (EM4J) and the EM4J plug-in for the vSphere Web Client. EM4J is the VMware memory management technology that improves memory utilization when executing Java workloads on VMware vSphere® ESXi™ virtual machines. The EM4J plug-in for the vSphere Web Client adds enhanced memory monitoring to the vSphere Web Client, which helps system administrators optimally size virtual machine memory, with or without EM4J-enabled Java workloads.

Intended Audience

Using vFabric Elastic Memory for Java is intended for anyone who wants to:

  • Configure and administer EM4J with vFabric tc Server™ runtime instances executing on VMware ESXi virtual machines.

  • Install the EM4J plug-in for vSphere Web Client and use it to monitor virtual machine memory.

  • Install the Console Guest Collector (CGC) on virtual machines to collect statistics about virtual memory utilization.
