我尝试在我的页面上设置跟踪，但没有帮助，因为页面只是挂起，我无法查看堆栈跟踪

在ISeries方面，我可以看到程序正确执行（对于测试，我在程序末尾的测试文件中写入一条记录）

以前有其他人遇到过这个错误吗？如果能在这方面得到任何帮助，我将不胜感激

谢谢

        GridView2.DataBind();

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

我一直在做以下工作：

    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();
我不记得该怎么做了，但这基本上就是我过去实施的方式。

这是很久以前提出的问题，但我还是会回答的

请查看此错误消息：

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

在搜索文本“没有上下文策略”后，我发现：

在这里，您将看到以下内容：

    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();
返回值
类型：
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“There no context policies”（无上下文策略）形成的字符串

那么，这意味着什么？ 最有可能的原因是：

ConfigurationManager.ConnectionStrings  ["db2IBM"].ConnectionString
你就是这么写的

该错误可能由以下任一原因引起：

  • 这些空格导致了错误，或者
  • db2IBM
    在Web.config文件的连接字符串部分中不存在
    • 有关设置连接字符串部分的帮助，请参阅以下内容：

        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();

    嗨，迈克，这和我现在的做法是一样的。该代码与Oledb驱动程序配合良好，因此我怀疑该代码是否存在问题。错误消息说“没有上下文策略”。这可能是因为我的机器上存在一些权限问题，还是因为我在DB2安装过程中遗漏了一些设置？我知道IBM iSeries.NET驱动程序可能很挑剔。在这样一个奇怪的错误中，尝试可能没有坏处。尤其是在OLEDB中工作时。对不起，除了三次检查你的权限之外，我没有其他建议。
