Subject A question about persistence using Oracle
Date Mon, 23 Jul 2007 06:06:19 GMT

I've configed my activemq.xml file like this : 

        <broker useJmx="false" xmlns="" > 

                        <transportConnector uri="tcp://localhost:61616" 
                                discoveryUri="multicast://default" /> 

                        <networkConnector uri="multicast://default" /> 

                <jdbcPersistence dataSourceRef="#oracle-ds" /> 

        <bean id="oracle-ds" class="org.apache.commons.dbcp.BasicDataSource" 
                <property name="driverClassName" 
                        value="oracle.jdbc.driver.OracleDriver" /> 
                <property name="url" 
                        value="jdbc:oracle:thin:@MYIP:1521:JDBC_USER" /> 
                <property name="username" value="user" /> 
                <property name="password" value="pass" /> 
                <property name="poolPreparedStatements" value="true" /> 

and i hope i can use Oracle for persistence ,but  it seems that the
persistence is done by Journal(actually , i don't konw what Journal is , it
seems the default persistence model), and the segment of log like : 
  信息: ActiveMQ 4.1.1 JMS Message Broker (localhost) is starting 
2007-7-20 18:27:49 getBroker 
信息: For help or more information please see:

信息: Journal Recovered: 0 message(s) in transactions recovered. 

so, can anybody tell me where the mistake lies?
