在尝试浏览 MFP Operational Analytics 的安装指南时，我在尝试启动 MFP 服务器时遇到了 OverlappingFileLockException。但是，当我从 Liberty Core 的 server.xml 中排除 Operational Analytics 时，不会发生此类问题。有没有人可以帮助我们解决这个问题？

我没有遇到这个问题，但这可能是因为我的做法是在自己的 Liberty 实例上安装 Operational Analytics 服务器。虽然这不是必需的，但它更接近于您在生产中使用的模式，您不仅会有一个单独的 Java EE Server 实例，而且可能会有一个或多个专用的 OA 机器。

技术说明http://www-01.ibm.com/support/docview.wss?uid=swg21664366解释说这是由于“JVM 中有多个 com.ibm.db2.jcc.DB2Driver 类的实例”。换句话说，应用服务器配置包含两个或多个“库”：

  • 在 Liberty 中，您有两个或更多元素来声明 DB2 JDBC 驱动程序。
  • 在 WebSphere Application Server Full Profile 中，您有两个或多个使用 DB2 JDBC 驱动程序的“JDBC 提供程序”。

解决方法是改用单个元素或单个 JDBC 提供程序。
