README.md

This document describes a simple prototype that demonstrates the use of Fuse ESB to manageTCP/IP controller failover.

Here is the design:

Client sends TCP/IP messages to ESB acting as a proxy. A failover-capable router pickups upmessages and sends them to Controller 1 using a TCP/IP service call. Controller 1 stamps themessage as having been processed and returns it to the router, and then back to the Clientapplication.

If Controller 1 fails, the router fails over to Controller 2. For purposes of a fast prototype, Controller 1and Controller 2 were run as simple Camel-Mina services run from the command line (external to theESB) so they were easy to kill to demonstrate failover. In practice, additional Fuse ESB containerswould be ideal to host controller services.

Software Requirements:

This repository



Download JBoss Fuse at http://www.redhat.com/jbossfuse/downloadUnzip the archive in a directory without spaces in its path.

There are three modules: applications, controllers and router. Here is the layout in the file system:

JBoss Fuse - RouterDemoclientcontrollerrouter

Run the command bin/fuse in the root directory of JBoss Fuse. Here is what the console looks like:

Launch a new terminal session, and run the command mvncleaninstall in the root directory of toplevel project. Make sure all projects build successfully.

In the JBoss Fuse terminal session run the command:

JBossFuse:karaf@root>features:installcamelminaJBossFuse:karaf@root>features:installcamelgroovyJBossFuse:karaf@root>osgi:installsmvn:com.fusesource.demo/proxyrouter/1.0.0SNAPSHOT

You should see output like this, with a Bundle ID generated by the deployment:

JBossFuse:karaf@root>osgi:installsmvn:com.fusesource.demo/proxyrouter/1.0.0SNAPSHOTBundleID:225JBossFuse:karaf@root>

Open two new terminal sessions and switch to the root of the controllers project in both. In onesession, execute this command to launch Controller 1:

controller$mvnPcontroller1

And in the other execute the command to launch Controller 2:

controller$mvnPcontroller2

Open a new terminal sessions and switch to the root of the applications project. In the session,execute this command to launch the test Client application:

client$mvncamel:run

You should see the Client sending and receiving messages like below. Notice the response has aelement, that initially contains 'Controller 1'

Kill the Controller 1 session any way you like, and you should see uninterrupted message flow, withController 2 handling the messages (note the changes to 'Controller 2' at message 12):

Restart Controller 1 and youll see it take control back from Controller 2 (this is user-defined behaviorin the configuration of the failover-load balancer)
