Subject Re: deployment of hundreds of client. broker name configuration problem?
Date Fri, 04 Dec 2009 09:09:07 GMT
Hi Sebastian,

An easy way is to modify the bin/activemq script to pass across an
activemq.hostname parameter.

e.g.  in bin/activemq, add:


and then in the line :

exec "$JAVACMD" $ACTIVEMQ_DEBUG_OPTS $ACTIVEMQ_OPTS -Dactivemq.classpath="${
ACTIVEMQ_CLASSPATH}" -Dactivemq.home="${ACTIVEMQ_HOME}" -Dactivemq.base="${ACTIV
EMQ_BASE}" -jar "${ACTIVEMQ_HOME}/bin/run.jar" start $@

add in  "-Dactivemq.hostname=${ACTIVEMQ_HOSTNAME} ".

If you use Java Wrapper and an init.d you can do a similar logic - set
the hostname in the init.d script as before, and in the wrapper.conf
do something like:

We use the second method in production successfully.
