Atomikos、Tomcat、事务日志和不观察系统属性

Question

我们在init（）中看到了与Strong Atomikos exception-error中描述的相同的内容：Log已经在使用？只不过我们遵循了文档，并将日志目录和基名指定为-d参数。在我们的例子中，它是一个war文件，部署到一个简单的Tomcat7容器实例中。

我不知道在这一点上我应该去哪里--我可能希望它试图打开的任何文件名都包括在日志中，但我盲目地飞行。除了通常的catalina和localhost日志之外，在/var/log/tomcat7中没有创建任何文件。

想法？

这是因为应用程序没有干净地关闭，它留下了一些剩余的日志锁，从而阻止了它的启动。

您需要找到应用程序的tmlogs文件夹。在该文件下，您将找到一个.epoch文件和一个.lck文件。删除这些，您的应用程序应该启动良好。
