ActiveMq Master/Slave & ServiceMix 4
Hi,
I have created a Master/Slave configuration of ActiveMq through 2
instances of ServiceMix 4 (so ActiveMq is in embedded mode) running on
the same host. The 2 instances of activemq have been deployed
successfully and run well. The two instances are configured to use the
same persistence adapter :
<persistenceAdapter>
<amqPersistenceAdapter syncOnWrite="false"
directory="d:/temp/activemq/default" maxFileLength="20 mb"/>
</persistenceAdapter>
I have created a queue (IN) and a message on the Master activeMq. If I
shutdown the Master activemq server, I see that the slave who was
sleeping wake up BUT
if I look (using jconsole) to the activemq config of the slave, I
don't see the queue IN + message posted and not consumed.
Is it normal or an issue ?
Additional remark : If I shutdown the SMX4 server (master) and restart it,
then the message + queue have been lost. Very strange isn't it !!!!
Kind regards,

Re: ActiveMq Master/Slave & ServiceMix 4

I use now the ProducerTool class to send "persistent" messages to my 'IN'
queue. So this problem is ok now.
Nevertheless, the second problem is always there. When I stop the activemq
master broker, the slave wakes up and becomes the master but through
Jconsole I cannot see the queue 'IN' + messages. I can see the following
components :
- broker
- connector
- openwire
- MasterConnector
IT SEEMS THAT THE JCONSOLE DOES NOT DISPLAY THE CORRECT INFO. If I use a JMS
client, it works fine as I'm able to get the messages from the queue IN.
Kind regards,
Charles

Re: ActiveMq Master/Slave & ServiceMix 4
Posted by cmoulliard <cm...@gmail.com>.
Hi Gary,
The persistence is on as I can it from jconsole (persistent = true).
When we create a message using the jconsole and command sendTextMessage, is
the message persisted or not ?
Here is the config of the master :
<broker xmlns="http://activemq.apache.org/schema/core"
brokerName="master" useShutdownHook="false">
<!-- Use the following to configure how ActiveMQ is exposed in JMX
-->
<managementContext>
<managementContext createConnector="true"/>
</managementContext>
<persistenceAdapter>
<kahaDB directory="d:/temp/activemq-data"
journalMaxFileLength="32mb"/>
</persistenceAdapter>
<!-- The transport connectors ActiveMQ will listen to -->
<transportConnectors>
<transportConnector name="openwire" uri="tcp://localhost:61616"/>
</transportConnectors>
</broker>
and the slave
<broker xmlns="http://activemq.apache.org/schema/core"
masterConnectorURI="tcp://localhost:61616" brokerName="slave"
useShutdownHook="false">
<!-- Use the following to configure how ActiveMQ is exposed in JMX
-->
<managementContext>
<managementContext createConnector="true"/>
</managementContext>
<persistenceAdapter>
<kahaDB directory="d:/temp/activemq-data"
journalMaxFileLength="32mb"/>
</persistenceAdapter>
<!-- The transport connectors ActiveMQ will listen to -->
<transportConnectors>
<transportConnector name="openwire"
uri="tcp://localhost:61617"/>
</transportConnectors>
</broker>
Kind regards,
Charles

you got to post your activemq.xml or broker bean, seems like u have
persistence turned off!
Or is the message non persistent?
