Elastic Memory for Java (EM4J) is included with vFabric tc Server Standard Edition. You enable EM4J in the ESXi virtual machine by adding a parameter to the virtual machine configuration and then use the tc Server elastic-memory template to create an EM4J-enabled tc Runtime instance.

EM4J works with all existing garbage collection policies and heap configurations and requires no special JVM tuning or configuration.
