The Historian is instrumented with JMX to allow you to manage and monitor application settings. To enable JMX, you must run the Historian using the -jmxport command line option:
-jmxport:(port number)
The JMX Monitor demo, located in demos\jmxmonitor in your RTView installation, shows how to use RTView to monitor the Historian using JMX.
