使用IBM DB2 Connect驱动程序在i Series上调用存储过程

我有一个C＃应用程序，我试图调用一个ISeries存储过程（包装一个RPGLE程序）。此RPGLE程序将结果集返回给我的C＃应用程序。当我尝试调用存储过程时，它会发生错误并无限期挂起。在调试模式下，我可以看到SQL错误消息，如帖子末尾所示。如果我使用OleDBConnection它可以正常工作，但它不适用于DB2 Connect。我试图在我的页面上设置跟踪，但它没有帮助，因为页面只是挂起而我无法查看堆栈跟踪。在ISeries方面，我可以看到程序正确执行（为了测试，我在程序结束时在测试文件中写一条记录。）之前有其他人遇到过此错误吗？我将不胜感激任何帮助。谢谢。码：-

DB2Connection conn1 = new DB2Connection(ConfigurationManager.ConnectionStrings  ["db2IBM"].ConnectionString);
        conn1.Open();

        string callString5 = "PGMLIBLE.GETCONSIGNMENTS";

        DB2Command cmd1 = new DB2Command(callString5, conn1);
        cmd1.CommandType = CommandType.StoredProcedure;
        cmd1.CommandTimeout = 5;

        DB2Parameter prmCons = cmd1.Parameters.Add("prmCons", DB2Type.Char, 7);
        prmCons.Direction = ParameterDirection.Input;
        prmCons.Value = "JUT0016";

        DB2Parameter prmCmp = cmd1.Parameters.Add("prmCmp", DB2Type.Char, 3);
        prmCmp.Direction = ParameterDirection.Input;
        prmCmp.Value = "DTA";

        DB2Parameter prmIorE = cmd1.Parameters.Add("prmIorE", DB2Type.Char, 1);
        prmIorE.Direction = ParameterDirection.Input;
        prmIorE.Value = "Y";

        DB2DataAdapter adp = new DB2DataAdapter(cmd1);
        DataTable dt = new DataTable();

        adp.Fill(dt);
     // If I just execute cmd1.executeNonquery it doesn't error.
     //  cmd1.ExecuteNonQuery(); 
        GridView2.DataSource = dt;
        GridView2.DataBind();

        conn1.Close();
        conn1.Dispose();
        cmd1.Dispose();

错误信息：-

我一直做以下事情：

    DB2Connection conn1 = new DB2Connection(ConfigurationManager.ConnectionStrings ["db2IBM"].ConnectionString);
    conn1.Open();

    string callString5 = "PGMLIBLE.GETCONSIGNMENTS";

    DB2Command cmd1 = new DB2Command(callString5, conn1);
    cmd1.CommandType = CommandType.StoredProcedure;
    cmd1.CommandTimeout = 5;

    cmd1.Parameters.Add("prmCons", DB2Type.Char, 7).Value = "JUT0016";
    prmCons.Direction = ParameterDirection.Input;

    cmd1.Parameters.Add("prmCmp", DB2Type.Char, 3).Value = "DTA";
    prmCmp.Direction = ParameterDirection.Input;

    cmd1.Parameters.Add("prmIorE", DB2Type.Char, 1).Value = "Y";
    prmIorE.Direction = ParameterDirection.Input;

    DB2DataAdapter adp = new DB2DataAdapter(cmd1);
    DataTable dt = new DataTable();

    adp.Fill(dt);
 // If I just execute cmd1.executeNonquery it doesn't error.
 //  cmd1.ExecuteNonQuery(); 
    GridView2.DataSource = dt;
    GridView2.DataBind();

    conn1.Close();
    conn1.Dispose();
    cmd1.Dispose();

我不记得如何做方向，但这基本上是我过去实现的方式。

很久以前就问过了这个问题，但无论如何我都会回答。看一下这个错误信息：错误[58005] [IBM] [DB2.NET] SQL0902进程中发生意外异常：5652线程10 AppDomain：名称：aa196883-1-129406018469512609 没有上下文策略。在搜索了“没有上下文策略”之后，我发现了这个： MSDN AppDomain.ToString方法在那里，您将看到以下内容：回报价值键入：System.String 通过连接文字字符串“Name：”，应用程序域的友好名称以及上下文策略的字符串表示形式或字符串“没有上下文策略”而形成的字符串。那么这是什么意思？最有可能的是，它来自于：

ConfigurationManager.ConnectionStrings  ["db2IBM"].ConnectionString

这正是你写它的方式。该错误可能是由以下任何一种引起的：那些空间导致错误，或您的Web.config文件的“连接字符串”部分中不存在db2IBM。有关设置“连接字符串”部分的帮助，请参阅以下内容：在ASP.NET中设置连接字符串到SQL SERVER
