Question

情况是我们想要使用XA事务来协调ActiveMQ和Hibernate（Sql Server 2008）之间的活动。

我们正在使用：

Spring 3.0.5
Hibernate 3.6.2
ActiveMQ 5.5.0
Atomikos 3.7

我们发现在与事务相关的日志文件中生成的以下错误尚未启动。这些始终与JMS相关。

交易＆＃39; [ID]＆＃39;尚未开始。

这些都会一直生成到日志中。

问题更复杂，因为我们有3个Web应用程序使用相同的JMS队列，并且当只有一个Web应用程序运行时似乎不会生成错误。

这些部署用于在同一台机器上运行的Tomcat 7.0.14的单独实例。

好的，我们在使用Atomikos在同一台机器上运行3个Tomcat Web应用程序时遇到了这个问题，这些应用程序指向同一个ActiveMQ服务器。

应用程序在单独的Tomcat实例中运行，并带有单独的Atomikos日志文件。

问题是XA XID（事务ID）在这三个应用程序中并不是唯一的，这导致ActiveMQ感到困惑。这是因为实例在同一台机器上运行。

如果将Atomikos和ActiveMQ记录设置为TRACE。然后，您可以看到两个或多个应用程序生成相同的XID。

这是因为Atomikos属性设置：com.atomikos.icatch.tm_unique_name

如果未设置，则在生成XID时使用计算机的IP地址，这对于三个应用程序是相同的并且会导致冲突。

这个问题只有在3个Tomcat应用程序彼此非常接近时才会发生。

因此，将com.atomikos.icatch.tm_unique_name设置为每个Web应用程序都是唯一的，问题就消失了。
