I'm seeing what I think may be some problems with multiple broker instances and AMQ 5.4.1. I've checked the docs and haven't found much information on the new scripts. Before I open a Jira or investigate/submit a patch, I wanted to make sure my assumptions aren't wrong.
First of all, I'm trying to create and run multiple instances as follows: 1) Create the instances: $ cd /home/phil/apache-activemq-5.4.1 $ bin/activemq create broker1 $ bin/activemq setup ~/.activemqrc-instance-broker1 $ ln -s activemq bin/activemq-instance-broker1 $ bin/activemq create broker2 $ bin/activemq setup ~/.activemqrc-instance-broker2 $ ln -s activemq bin/activemq-instance-broker2 2) set unique ports for the instances in their conf/activemq.xml and conf/jetty.xml files as shown below: $ grep 16 broker[12]/conf/*.xml broker1/conf/activemq.xml: <transportConnector name="openwire" uri="tcp://0.0.0.0:61616"/> broker1/conf/jetty.xml: <property name="port" value="8161" /> broker2/conf/activemq.xml: <transportConnector name="openwire" uri="tcp://0.0.0.0:61626"/> broker2/conf/jetty.xml: <property name="port" value="8162" /> When I try to start both brokers, I get a "Process with pid XXX is already running" message. This is due to the pid file being created in $ACTIVEMQ_HOME/data rather than the instance's $ACTIVEMQ_BASE/data directory. For now, my questions are: 1) Should $ACTIVEMQ_HOME point to the AMQ installation directory and $ACTIVEMQ_BASE point to the specific instance directories? 2) What should be in the ~/.activemqrc-instance-<INSTANCENAME> files? Should I set the $ACTIVEMQ_BASE here? I tried this but it didn't seem to work. 3) Should $ACTIVEMQ_HOME/bin/activemq-instance-<INSTANCENAME> simply be a symbolic link to the ACTIVEMQ_HOME/bin/activemq script? 4) How should the instances be started? Using the bin/activemq-instance-<INSTANCENAME>? Or using <INSTANCENAME>/bin/<INSTANCENAME> (in my case, broker1/bin/broker1 if run from $ACTIVEMQ_HOME) Thanks, Phil
