From Fuse 6.2, the prefix is changed from org.fusesource.mq.fabric.server- to io.fabric8.mq.fabric.server-. So description about PID prefix and content of example needs to be updated.

"JBoss Fuse 6.3 Configuring And Running JBoss Fuse: CHAPTER 10. DEPLOYING A NEW BROKER INSTANCE"
https://access.redhat.com/documentation/en/red-hat-jboss-fuse/6.3/paged/configuring-and-running-jboss-fuse/chapter-10-deploying-a-new-broker-instance

CHAPTER11 needs to be fixed too.
->broker.xml org.fusesource.mq.fabric.server-default.cfg //need to fix the file name
->org.fusesource.bai.agent.cfg //need to fix. The file is not exist after 6.2
->org.fusesource.mq.fabric.server-default.cfg //need to fix the file name

This is the list of file name for each Fuse version:

• 6.0: org.fusesource.mq.fabric.server-default.cfg
• 6.1: org.fusesource.mq.fabric.server-default.cfg
• 6.2: io.fabric8.mq.fabric.server-broker.cfg
• 6.2.1: io.fabric8.mq.fabric.server-broker.cfg
• 6.3: io.fabric8.mq.fabric.server-broker.cfg
