XMS - 如何在網絡中斷後恢復與WebSphere SIBus的連接

我正在連接到JMS隊列。隊列由WebSphere Application Server（版本8.0.0.5）使用SIBus進行託管。XMS - 如何在網絡中斷後恢復與WebSphere SIBus的連接

我有一個簡單的程序來重現一些有問題的行爲，它用C＃編寫並使用XMS（IBM的.NET API）連接到隊列。注意：我得從這裏IBM.XMS dll文件：MQC71: WebSphere MQ V7.1 Clients

的情況是這樣的：

運行程序（使用空隊列，所以它坐落在等待阻塞收取來電）
斷開網絡（拔掉以太網）
幾分鐘後，接收呼叫拋出異常
程序試圖重新連接
失敗由於網絡是向下
...讓它循環一點來驗證這個錯誤持續發生
恢復網絡（以太網插頭）
同樣的錯誤繼續出現（驗證使用Wireshark該connectionFactory.CreateConnection（）調用期間沒有出現網絡流量）

所以，問題是：爲何創建連接（）調用什麼都不做（不發送任何數據包），但失敗了呢？

注意，在上面的輸出我拔掉了網後不久，「接收...」並插入它再次16點43分52秒，但之後錯誤繼續，直到我殺了程序。

它讀取像ConnectionFactory在網絡再次可用時不會正確重置它的狀態。

我已經在參考手冊上找到了工廠的任何重置功能提示 - 但沒有找到。但我會試試這個：將GetInstance(...)和createConnectionFactory()移出循環，以及SetStringProperty()行。

如果這不起作用，我不明白爲什麼你的客戶不會工作。你有沒有考慮過，如果這是服務器的問題？你拔下了哪根以太網電纜？連接到客戶端或服務器的那個？如果是服務器，拔出客戶端電纜時是否會發生同樣的問題？如果你重新啓動程序，它會工作嗎？

重新啓動後，程序會正常連接到隊列。我拔掉了將客戶端連接到網絡的網線。 – Anssssss 2013-03-22 13:39:17

然後，要麼在循環之外移動一些行的建議應該可行 - 或者看起來它很可能是框架中的一個錯誤。 – fredrik 2013-03-22 14:28:03

我試過你的建議（移動循環外部的connectionFactory的創建和初始化）。相同的錯誤條件結果。請注意，如果您擁有IBM的客戶帳戶並且可以創建它，那麼我會接受IBM的錯誤報告作爲足夠的答案。如果沒有解決方法/修復，那麼我將開始研究如何卸載/重新加載XMS DLL（希望這相當於重新啓動應用程序）。 – Anssssss 2013-03-22 14:54:44

我知道這是一箇舊帖子，但也許它仍然有幫助。

在創建65.535連接後收到此錯誤。關閉連接/處理對象無關緊要。

我看到以下解決方案：

1。）您可以創建一次連接，並將連接重新用於隊列上的所有操作，直到連接中斷。然後你必須重新連接。（是的，這是壞的和反對的共同模式，我不會建議這樣做）

2.）有一個版本8.0.0.6可用的錯誤修正。 編輯：APAR＃（IJ01244） 我還不知道它何時會包含到未來版本中。我想你可以聯繫IBM的支持，並參考這個PMR ID來接收IBM.XMS.SIB.dll的更新版本

希望這會有所幫助。
