Hi everybody I managed to make my ActiveMQ broker persistent - however I'm not quite sure if it's running the way it should. Every time i start up the broker, it writes the following to the log:
INFO KahaStore - Kaha Store using data directory /usr/local/activemq/activemq-data/kr-store/state INFO AMQPersistenceAdapter - Active data files: [] WARN AMQPersistenceAdapter - The ReferenceStore is not valid - recovering ... INFO KahaStore - Kaha Store successfully deleted data directory /usr/local/activemq/activemq-data/kr-store/data INFO AMQPersistenceAdapter - Journal Recovery Started from: DataManager:(data-) INFO KahaStore - Kaha Store using data directory /usr/local/activemq/activemq-data/kr-store/data INFO AMQPersistenceAdapter - Recovered 310047 operations from redo log in 212.301 seconds. INFO AMQPersistenceAdapter - Finished recovering the ReferenceStore Obviously, recovering from the journal (= redo log, correct?) is quite slow. Shouldn't ActiveMQ recover from the Kaha Reference Store instead? Unfortunately, I'm getting a "The ReferenceStore is not valid" all the time. Here's my config: <broker xmlns="http://activemq.org/config/1.0"; brokerName="localhost" persistent="true" useShutdownHook="false" dataDirectory="${activemq.base}/data"> <!-- The transport connectors ActiveMQ will listen to --> <transportConnectors> <transportConnector name="stomp" uri="stomp://localhost:61613"/> </transportConnectors> <!-- Use the following if you wish to configure the journal with JDBC --> <persistenceAdapter> <amqPersistenceAdapter directory="${activemq.base}/activemq-data" maxFileLength="32mb"/> </persistenceAdapter> </broker> Aside from that, I have some other questions: 1. Persistent messages that are recovered on startup don't appear in the admin console. However, I'm able to subscribe and receive them, which confuses the console even more and makes it show a negative number in "Number Of Pending Messages". Is this normal or is it related to the fact, that my messages are not properly persisting? 2. ActiveMQ chokes (it sometimes takes seconds until the messages start arriving), when trying to receive recovered messages after startup (at least for > 100k messages). I guess, that's normal, since it's a lot of messages... is that correct? 3. What's the useShutdownHook="false" for, which I see in all ActiveMQ conf examples? Thanks in advance! & Cheers!
