【问题描述】：

我正在尝试建立与 ORACLE 10g 数据库的数据库连接。我在下面粘贴了错误信息。我正在寻找有关该问题的一些信息。

系统配置：

Windows XP SP2
ARCH：AMD 64 位
TIBCOE SpotFire 64 位

错误消息：无法打开数据源。

【解决方案1】：

这里的关键错误是：

BadImageFormatException at System.Data.OracleClient: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) (HRESULT: 8007000B)

如果您尝试将 32 位 DLL 加载到 64 位应用程序中，则可能会出现 BadImageFormatException，反之亦然。

从它的声音来看，要么：

您没有安装 64 位 Oracle 客户端驱动程序，或者
连接字符串正在尝试加载 32 位 Oracle 客户端驱动程序，或者
客户端驱动程序实际上已损坏。

似乎有一种方法可以强制 Spotfire 在 32 位模式下运行，https://tibbr.tibcommunity.com/tibbr/#!/messages/66091，但我不知道怎么做。有谁知道如何强制 Spotfire 在 32 位模式下运行？
