轉移到Glassfish-2.x羣集會導致連接在1小時後超時

Question

我們最近從Glassfish-2.x遷移到非Glassfish-2.x羣集環境。部分舉措包括在IIOP上使用RMI而不是連接到靜態服務器。除非我們的客戶端應用程序閒置一個多小時，服務器的連接被服務器終止，從而阻止我們執行任何查找，否則一切都會很好。我們想知道如何保持連接數小時。操作系統設置爲保持連接2小時（/ proc/sys/net/ipv4/tcp_keepalive_time）。是否有通過IIOP連接Glassfish中設置的超時限制，以及如何改變它？

在您的服務器和客戶端之間是否存在防火牆？我們有這個相同的錯誤，事實證明防火牆正在丟棄連接。
