Sebastien Rodriguez commented on AMQ-3042:
------------------------------------------

The problem is that I'm quite sure this is platform dependent: in Windows machine you need to put: 
brokerName="${COMPUTERNAME}"
in the configuration file

>                 Key: AMQ-3042
>                 URL: https://issues.apache.org/activemq/browse/AMQ-3042
>             Project: ActiveMQ
>          Issue Type: Improvement
>          Components: Broker
>    Affects Versions: 5.4.1
>            Reporter: James Green
>            Priority: Trivial

> In many scenarios, including ours, there is one AMQ broker per host. They connect to each other but must have unique brokerName values.
> It would therefore make sense to send into AMQ at launch the current hostname and refer to this for the value instead of the literal value "localhost".
> This would lend itself to invoking lots of new broker hosts within a virtualised environment with reduced configuration work.
> The init.d script could have two lines added:
> ACTIVEMQ_HOSTNAME=`hostname`
> ACTIVEMQ_OPTS="-Denv.hostname=$ACTIVEMQ_HOSTNAME"
> The activemq.xml file that ships default could then read:
>     <!--
>         The <broker> element is used to configure the ActiveMQ broker.
>     -->
>     <broker xmlns="http://activemq.apache.org/schema/core" brokerName="${env.hostname}" dataDirectory="${activemq.base}/data" destroyApplicationContextOnStop="true">
> Unsure about other platforms but that works for linux.
