#Camel Singleton Policy

This is an example org.apache.camel.spi.RoutePolicy implementation that allows you to use a lock file to ensure a single instance of a route running in a cluster.

##Requirements

• Apache Maven 3.x

##Building Example

Run the Maven build

~$ cd $PROJECT_ROOT
~$ mvn clean install

##Running Camel

Open up two terminal windows.

Terminal 1:

~$ cd $PROJECT_ROOT
~$ mvn -DlockFile=/tmp/singletonTimer.lck -DinstanceId=instance01 camel:run

Terminal 2:

~$ cd $PROJECT_ROOT
~$ mvn -DlockFile=/tmp/singletonTimer.lck -DinstanceId=instance02 camel:run

##Testing

You should see log statements from the timer route in only one terminal at a time. You can kill the currently active process and watch the other one start and begin logging messages.
