Spring JMS Oracle AQ 事务过多

Question

我创建了一个基本的 Spring 应用程序来读取 Oracle AQ。我遇到以下问题。请在这方面帮助我

1)- 在启动我的 Spring 应用程序之前放置在队列上的消息（通过 PL/SQL 代码）不会被它出列。 2)- 从队列中成功读取的消息应从队列中删除。这并没有发生。所有消息都保留在队列表中。 3)- 一旦读取了一条消息，进程就会进入阻塞/等待状态，如下面的日志所示，如果在此期间有任何消息放入队列，则该消息将被忽略。提交事务需要 30 - 40 秒

2012-02-08 13:26:37,700 DEBUG [org.springframework.data.jdbc.jms.listener.oracle.AdtMessageListenerContainer] - <Received message of type [class oracle.jms.AQjmsAdtMessage] from consumer [oracle.jms.AQjmsConsumer@1989b5] of transactional session [oracle.jms.AQjmsSession@189c036]>

4)- 为什么会进行如此多的事务？在等待队列时
