Hello all I am experiencing troubles getting ActiveMQ use the master/slave on shared file system new feature.
Configuration : ActiveMQ 4.0.1 (home dir = /vol03/ActiveMQ/4.0.1) RedHat 4 Disk Array on GFS It looks straight forward on the web site, but I can't get it work. Here is what the web site suggests : <persistenceAdapter> <journaledJDBC dataDirectory="/sharedFileSystem/broker"/> </persistenceAdapter> What I am trying to reach is pretty simple : 2 brokers in cluster: "BrokerA" and "BrokerB". Each one of them has its slave...respectively: "BrokerAbck" and "BrokerB2bck" So I created 4 xml files: BrokerA.xml BrokerAbck.xml BrokerB.xml BrokerBbck.xml BrokerA.xml : =========================================== <beans xmlns="http://activemq.org/config/1.0";> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/> <broker useJmx="false" brokerName="BrokerA" persistent="true" deleteAllMessagesOnStartup="false" start="true" shutdownOnMasterFailure="false" useLoggingForShutdownErrors="true" useShutdownHook="true" populateJMSXUserID="true" > <managementContext> <managementContext connectorPort="1099" jmxDomainName="org.apache.activemq"/> </managementContext> <persistenceAdapter> <journaledJDBC journalLogFiles="5" useJournal="true" dataDirectory="/vol03/ActiveMQ/4.0.1/data/BrokerA"/> </persistenceAdapter> <transportConnectors> <transportConnector name="default" uri="tcp://localhost:4501" discoveryUri="multicast://default"/> </transportConnectors> <networkConnectors> <networkConnector name="default" uri="multicast://default"/> </networkConnectors> </broker> </beans> BrokerAbck.xml : =========================================== <beans xmlns="http://activemq.org/config/1.0";> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"/> <broker useJmx="false" brokerName="BrokerAbck" persistent="true" deleteAllMessagesOnStartup="false" start="true" shutdownOnMasterFailure="false" useLoggingForShutdownErrors="true" useShutdownHook="true" populateJMSXUserID="true" > <managementContext> <managementContext connectorPort="1099" jmxDomainName="org.apache.activemq"/> </managementContext> <persistenceAdapter> <journaledJDBC journalLogFiles="5" useJournal="true" dataDirectory="/vol03/ActiveMQ/4.0.1/data/BrokerA"/> </persistenceAdapter> <transportConnectors> <transportConnector name="default" uri="tcp://localhost:4501" discoveryUri="multicast://default"/> </transportConnectors> <networkConnectors> <networkConnector name="default" uri="multicast://default"/> </networkConnectors> </broker> </beans> =================================================== BrokerA starts perfectly. BrokerAbck fails with the following error: ACTIVEMQ_HOME: /vol03/ActiveMQ/4.0.1 Loading message broker from: xbean:file:../conf/BrokerA2.xml ERROR: java.lang.RuntimeException: Failed to execute start task. Reason: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.activemq.store.PersistenceAdapterFactoryBean': FactoryBean threw exception on object creation; nested exception is java.io.IOException: Journal is already opened by another application ERROR: java.lang.Exception: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.apache.activemq.store.PersistenceAdapterFactoryBean': FactoryBean threw exception on object creation; nested exception is java.io.IOException: Journal is already opened by another application Can anyone help? I really need this to be working very soon. I haven't tried the Pure Master/Slave solution....and do not really want to as the recovery procedure isn't automatic.
