For information about the effect of this and other server properties on Hyperic performance, see Scaling and Tuning Hyperic Performance.

In Hyperic HQ the default value is: -XX:MaxPermSize=192m -Xmx512m -Xms512m -XX:+HeapDumpOnOutOfMemoryError -XX:+UseConcMarkSweepGC

In vFabric Hyperic, the value of the property can vary by the installation profile for the Hyperic Server.

  • small — -XX:MaxPermSize=192m -Xmx512m -Xms512m -XX:+HeapDumpOnOutOfMemoryError -XX:+UseConcMarkSweepGC

  • medium — -Djava.awt.headless=true -XX:MaxPermSize=192m -Xmx4g -Xms4g -XX:+HeapDumpOnOutOfMemoryError -XX:+UseConcMarkSweepGC

  • large — -Djava.awt.headless=true -XX:MaxPermSize=192m -Xmx8g -Xms8g -XX:+HeapDumpOnOutOfMemoryError -XX:SurvivorRatio=12 -XX:+UseConcMarkSweepGC -XX:+UseCompressedOops -Xmn4g
