Try to cluster instances and obtain... Journal is locked... what is that?

[Grzegorz Kokosiński <gk...@touk.pl>]

Hi.
I try to cluster two instances of servicemix. Each of them is run  
independly. I set network connector to each other. In each brokerName is  
the same.
One of them writes in logs that:

INFO  - org.apache.activemq.store.DefaultPersistenceAdapterFactory   -  
Journal is locked... waiting 10 seconds for the journal to be unlocked.

After that I can not close that instance, I have to kill it.

What does it mean?

This a piece of $SMX/conf/activemq.xml:

First one:

<beans xmlns:amq="http://activemq.org/config/1.0">

   <amq:broker id="broker" brokerName="broker" depends-on="jmxServer"  
useShutdownHook="false">

     <amq:transportConnectors>
        <amq:transportConnector uri="tcp://localhost:61617"/> <!--  
discoveryUri="multicast://default"/-->
     </amq:transportConnectors>

     <amq:networkConnectors>
       <amq:networkConnector uri="static://(tcp://localhost:61616)"/>
     </amq:networkConnectors>

      <!-- the rest of config -->

</beans>

Second one:
<beans xmlns:amq="http://activemq.org/config/1.0">

   <amq:broker id="broker" brokerName="broker" depends-on="jmxServer"  
useShutdownHook="false">

     <amq:transportConnectors>
        <amq:transportConnector uri="tcp://localhost:61616"/> <!--  
discoveryUri="multicast://default"/-->
     </amq:transportConnectors>

     <amq:networkConnectors>
       <amq:networkConnector uri="static://(tcp://localhost:61617)"/>
     </amq:networkConnectors>

      <!-- the rest of config -->

</beans>

Thanks in advance.

You transportConnector and networkConnector entries look fine.  I am
guessing that since you appear to be running these instances on the same
host, you probebly need to look at the ActiveMQ persistenceAdapter entry in
activemq.xml and make sure they are pointing to different locations for the
journal data.  This message leads me to believe that the instances are
looking at the same location, so the first instance starts fine, and the
second one can't lock the journal.
