Hot Deploying External Classes Using JMX

After you have configured the system and generated decision table class files for deployment, you can hot deploy the classes to running TIBCO BusinessEvents engines using JMX.

You can also unload a deployed decision table from a running engine. The system pauses briefly until the procedure is complete.

You might want to use these techniques, for example if you want to replace one VRF implementation (decision table) with a different one.

Procedure

  1. Open a command window in the bin directory of your JDK installation and type jconsole.
    You see the New Connection dialog.
  2. Select the connection corresponding to the TIBCO BusinessEvents node that you want to view and click Connect. Each node runs in single JVM.
    You see the multi-tabbed Connection dialog.
  3. Select the MBeans tab and expand the tree nodes on the left to com.tibco.be > > Cluster > Operations.
  4. Do the following as appropriate:
    • Click loadAndDeploy. All decision table class files in the preconfigured location are deployed to all nodes in the cluster.
    • Specify the project path to the virtual rule function and the decision table name and click loadAndDeploy. The corresponding class is loaded into the cache and deployed to all engines.
    • Specify the project path to the virtual rule function and the decision table name and click unloadClass. The corresponding class is unloaded.
