两个HornetQ服务器之间的HornetQ JMS Bridge无法提供

(编辑于11.11.11,编辑在底部)

我有两台运行HornetQ(版本2.2.5 AS7)服务器的JBoss AS 6.1服务器。 让我们调用另一个CLIENT和另一个MASTER。

CLIENT有一个Queue(“sourceQueue”),由我们的Web应用程序写入。

在CLIENT和MASTER服务器之间设置了JMS桥, 它会在CLIENT上使用来自sourceQueue的消息,并且应该生成它们 MASTER上的targetQueue。该桥正在CLIENT JBoss上运行。

问题:而不是从源上消费并在目标上生成消息,表面上似乎没有任何事情发生:源有1条消息,目标没有。也可能一次又一次地向源发送消息。

使用netty连接器的网络连接正在运行,已经测试重新启动网桥并观察netstat -n -c输出。

哪种问题会导致这类问题?

  • 网络问题?
  • 交易经理?
  • 连接器错误?

你将如何诊断HornetQ桥的问题?

以下是hornetq-jboss-beans.xml上的桥接定义(在CLIENT / jboss / server / default / deploy / hornetq上)。定义是HornetQ manual上的JMS桥示例的近似变体:

CLIENT端hornetq-jms.xml上的队列定义:

修改 出于某种原因,如果我在两个服务器完全部署后停止并重新启动网桥,则网桥会开始传输消息。这是一个手动过程,我不喜欢使用hack来定期重启桥。我欢迎任何关于这个问题的建议。

我还通过使桥接器依赖于它读取的队列来改进启动顺序 - 否则桥接器在队列之前启动,导致错误记录。

查看此帖子: https://issues.jboss.org/browse/HORNETQ-247 它提供了一些有关如何公开核心队列并在核心桥中使用它们的见解。

为什么不使用核心桥?
