Configuring for Deployment and Unloading of Decision Table Classes

Before deployment configure the deployment properties in the CDD file for deployment of classes at application startup, and for hot deployment and unloading of classes.

For class file deployment, including hot deployment, you configure the following items:

  • The location where the deployed application looks for the class files for deployment.
  • Which engine or engines can and cannot function as class loaders.

At application startup, the first class loader that starts will load the generated classes from the preconfigured location to the cache, and other engines pick them up from the cache.

For hot deployment, you use JMX (and RMI for remote invocations) to load the class files into the cache, which causes them to be deployed to all engines.

You can also use JMX to unload class files from a running engine.
