移动到Glassfish-2.x群集导致连接在1小时后超时

Question

我们最近从Glassfish-2.x非集群环境迁移到了Glassfish-2.x集群环境。移动的一部分包括使用RMI over IIOP，而不是连接到静态服务器。一切都运行得很好，除了当我们的客户端应用程序空闲超过一个小时时，服务器会终止与服务器的连接，从而阻止我们进行任何查找。我们想知道如何使连接保持活动状态几个小时。操作系统设置为使连接保持打开2小时(/proc/sys/net/ipv4/tcp_keepalive_time)。在glassfish中是否为IIOP上的连接设置了超时限制?如果有，我如何更改它？

您的服务器和客户端之间是否有防火墙？我们遇到了同样的错误，结果发现防火墙正在丢弃连接。
