CreateTopic上的IBM MQ XMS錯誤2085

Question

我正在嘗試創建主題並將消息發佈到IBM MQ主題。我正在獲取2085 MQ異常，並確定如何解決此問題。
我使用的IBM.XMS.dll版本是8.0.0.6。

控制檯應用程序代碼：

static void Main(string[] args) 
    { 
     try 
     { 
      XMSFactoryFactory factoryFactory = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ); 

      IConnectionFactory connectionFactory = factoryFactory.CreateConnectionFactory(); 
      Console.WriteLine("Connection Factory created."); 

      connectionFactory.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, "MQ_TX_MGR"); 
      connectionFactory.SetStringProperty(XMSC.WMQ_CONNECTION_NAME_LIST, "10.10.10.10(1414)"); 
      connectionFactory.SetStringProperty(XMSC.WMQ_CHANNEL, "CL.SVRCONN"); 

      connectionFactory.SetIntProperty(XMSC.WMQ_CONNECTION_MODE, XMSC.WMQ_CM_CLIENT); 
      connectionFactory.SetIntProperty(XMSC.WMQ_CLIENT_RECONNECT_OPTIONS, XMSC.WMQ_CLIENT_RECONNECT); 
      connectionFactory.SetIntProperty(XMSC.WMQ_CLIENT_RECONNECT_TIMEOUT, 3); 

      mqConnection = connectionFactory.CreateConnection(); 
      Console.WriteLine("Connection created."); 

      session = mqConnection.CreateSession(false, AcknowledgeMode.AutoAcknowledge); 
      Console.WriteLine("Session created."); 


      IDestination destination = session.CreateTopic("topic://TOPIC/NAME"); // destinationName 
      Console.WriteLine("Destination created."); 

      // create producer 
      IMessageProducer producer = session.CreateProducer(destination); //My Code is erroring out at this line. 

     } 
     catch (Exception ex) 
     { 
      Console.WriteLine(ex.Message); 
     } 
     finally 
     { 
      Console.WriteLine("Program waiting for message:"); 
      Console.ReadLine(); 
     } 

    }

確保您的SVRCONN頻道的SHARECNV值等於或大於1。

IBM MQ V8知識中心頁面 「MQI client: Default behavior of client-connection and server-connection channels」 記錄了以下有關SHARECNV(0)：

This value specifies no sharing of conversations over a TCP/IP socket. The channel instance behaves exactly as if it was a Version 6.0 server or client connection channel, and you do not get the extra features such as bi-directional heartbeats that are available when you set SHARECNV to 1 or greater. Only use a value of 0 if you have existing client applications that do not run correctly when you set SHARECNV to 1 or greater.

IBM的MQ V8知識中心頁面 「XMSC_WMQ_PROVIDER_VERSION」 記載了以下內容：

By default this property is set to "unspecified".

...

IBM WebSphere MQ Version 7.0 specific features are disabled if XMSC_WMQ_PROVIDER_VERSION is set to UNSPECIFIED and SHARECNV is set to 0.

這將導致XMS嘗試使用STREAM隊列發佈排隊發佈/訂閱的消息。將其設置爲1或更高可獲得v7風格的連接，並使用普通的v7集成發佈/訂閱。

在以前的某些版本中，設置SHARECNV(0)是解決某些問題的方法，我不知道有任何v8問題可以解決此問題。

指定主題目標必須以 「主題：//」 開頭的語法。例如session.CreateTopic("topic://Score/Football")。有關更多詳細信息，請參閱文檔 here。
