Atomikos，Tomcat，事務日志並且不觀察系統屬性

Question

我們看到的內容與Strange Atomikos異常中描述的相同-init（）中的錯誤：日志已在使用中？ 除了我們已遵循文檔並指定日志目錄和基本名稱作為-D參數外。 在我們的案例中，這是一個部署到朴素的Tomcat7容器實例中的war文件。

日志中沒有證據表明正在讀取系統屬性。

這是Atomikos的3.9.3版本。

我不知道此時該去哪里-我可能希望它試圖打開的任何文件名都包含在日志中，但我視而不見。 除了通常的catalina和localhost日志外，沒有在/ var / log / tomcat7內部創建任何文件。

想法？

Answer 1

這是因為該應用程序尚未完全關閉，並且留下了一些殘留的日志鎖，進而阻止了它的啟動。

您需要找到應用程序的tmlogs文件夾。 在此之下，您將找到一個.epoch文件和一個.lck文件。 刪除這些，您的應用程序應該可以正常啟動。
