在某些平台上使用odbc时出错（32位对64位）

Question

我们使用Installshield来安装我们的一个应用程序。

其中一个步骤需要输入Oracle实例的连接字符串。

在Installshield中，我们使用ODBC打开oracle连接并在数据库上运行一些脚本。

我们在Windows 8或Windows 2012服务器上安装时遇到包问题。

我们在Installshield中遇到此错误，与ODBC版本有关：

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified Source: Microsoft OLE DB Provider for ODBC Drivers SQL State: IM002 Native Error: 0 

我们知道它与ODBC版本（32位对64位）有关，它们都位于此处：

C:\Windows\SysWOW64\odbcad32.exe

要么

C:\Windows\System32\odbcad32.exe

为了真正测试这个问题，我创建了一个控制台应用程序，它将打开和关闭odbc连接并将错误记录在文本文件中。

这是小样本：

using System.Data.Odbc;
using System.IO;

static void Main(string[] args)
{
    TextWriter tw = new StreamWriter("Errors.txt");
    Console.WriteLine("Enter the Server Name:");
    var Server = Console.ReadLine();
    Console.WriteLine("Enter the Instance Name:");
    var instancename = Console.ReadLine();
    try
    {
        OdbcConnection DbConnection = new OdbcConnection("Driver= {Microsoft ODBC for Oracle};Server=" + Server + ":1521/" + instancename + ";Uid=system;Pwd=manager;");
        DbConnection.Open();
        DbConnection.Close();
        tw.WriteLine("No errors");
    }
    catch (Exception e)
    {
        tw.WriteLine(e);
    }
    finally
    {
        tw.Close();
    }
}

如果我从我的具有oracle服务器的计算机上运行这个小工具，它可以正常工作。 我在几个其他服务器和具有oracle实例的计算机上测试它也可以正常工作。

我们发现在Windows服务器2012或窗口8上，连接无法打开。

当我在x86中编译我的应用程序时：

我得到此消息错误，这与安装盾引发的错误相同：

System.Data.Odbc.OdbcException (0x80131937): ERROR [NA000] [Microsoft][ODBC driver for Oracle][Oracle]Error while trying to retrieve text for error ORA-01019

   at System.Data.ProviderBase.DbConnectionInternal.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory)
   at System.Data.Odbc.OdbcConnection.Open()

当我在x64中编译它时，我收到一个不同的错误消息：

   at System.Data.ProviderBase.DbConnectionInternal.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory)
   at System.Data.Odbc.OdbcConnection.Open()

任何提示？

我有一些丢失的dll吗？ 我在哪里可以下载它们？

根据此http://msdn.microsoft.com/en-us/library/ms713590%28v=vs.85%29.aspx “此功能将在未来的Windows版本中删除。避免在新开发中使用此功能工作，并计划修改当前使用此功能的应用程序。而是使用Oracle提供的ODBC驱动程序。“

我的建议是使用ODP.Net（它们有32位和64位驱动程序，可以同时安装） http://www.oracle.com/technetwork/topics/dotnet/downloads/index.html
