我们正在切换到 Windows Server 2008 R2 64 位服务器并且遇到了一些问题。我们的 Windows 服务在 Windows 事件日志中抛出“AccessViolationException”异常。我们在旧的 Windows 2003 32 位服务器上从未遇到过这个问题。唯一的应用程序更改是重新编译为 64 位应用程序。

不知道是代码问题,还是服务器设置问题。任何人都知道为什么会发生这种情况?

更新:

这是两个堆栈跟踪:

讨论了由大于 40 字节的连接字符串引起的缓冲区溢出问题。我怀疑这是同一个问题,但是您可以尝试 OP 的解决方法来查看它是否相关:

作为解决方法,我不会解析连接字符串中的数据源(目标是在不使用 tnsnames.ora 的情况下分发 Oracle 应用程序)。

如果您的 conn 字符串小于 40 字节,并且您仍然看到异常,我会联系 oracle 并查看他们是否有更新的驱动程序。
