Question

我遇到一个问题，我的JMS消息桥似乎每隔30秒就被WLS停止并重新启动。

据我所知，网桥实际上正常工作，WLS控制台将其报告为“活动，转发消息”。在桥梁两端的两个队列都是我所知道的最佳工作。

每30秒在我的WLS日志中显示的消息如下所示。每次都会重复这六行。

####<2011-sep-20 kl 12:48 CEST> <Info> <MessagingBridge> <host> <server> <[ACTIVE] ExecuteThread: '20' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1316515696279> <BEA-200020> <Bridge "NameOfBridge" is stopped.>

查看配置后，唯一相似的数字是“Transaction Timeout”，设置为30。这意味着网桥直接打开一个事务，然后失败（或者因为我配置了错误，或者只是因为没有发生任何事情），然后关闭事务/网桥并重新启动它。我不希望这种行为，但也许它是如何运作的？

我正在使用WLS 10.3.0.0。

更新：config.xml的相关配置：

<messaging-bridge>
  <name>NameOfBridge</name>
  <target>servercluster</target>
  <source-destination>NameOfBridgeLocalDest</source-destination>
  <target-destination>NameOfBridgeRemoteDest</target-destination>
  <selector></selector>
  <quality-of-service>Exactly-once</quality-of-service>
  <started>true</started>
</messaging-bridge>

As per this Oracle support document（需要Oracle帐户），这是异步JMS网桥的正常行为。

文档中的问题描述如下：

使用WebLogic Server 9.2及更高版本;在已配置JMS并设置JMS消息传递桥的域中，JMS消息桥的日志记录显示每30秒断开连接并重新连接到源目标。

从Oracle的角度来看，这是正常的预期行为：

这是一种轮询机制，通常在源目标中没有消息时以及消息桥处于空闲状态时发生。

由于这是预期的异步桥，因此停止它的方法是禁用JMS消息传递桥的“启用异步模式”选项，这将停止轮询。

为什么我的JMS消息桥接器在WLS中每30秒停止/启动一次
