無法使用Powershell爲Oracle加載文件或程序集

Question

我無法使用OTP .NET庫在Windows Server 2012計算機上從Powershell查詢Oracle。

我下載ODP.NET_Managed_ODAC12cR4.zip與

install_odpm.bat c:\oracle x64 false 

在我沒有安裝Oracle的服務器上安裝。

這條線：

Add-Type -Path "C:/oracle/odp.net/managed/common/Oracle.ManagedDataAccess.dll" 

或該行：

[System.Reflection.Assembly]::LoadFrom("C:/oracle/odp.net/managed/common/Oracle.ManagedDataAccess.dll") 

兩個給我下面的錯誤：

PS C:\temp> .\impoinftel.ps1 
Exception calling "LoadFrom" with "1" argument(s): "Could not load file or 
assembly

vcredist_x64.exe安裝在我的服務器

上

powershell.exe.c onfig如下：

<?xml version="1.0" encoding="utf-8" ?> 
<configuration> 
    <startup useLegacyV2RuntimeActivationPolicy="true"> 
     <supportedRuntime version="v4.0" />  
    </startup> 
</configuration>

您可能需要解鎖這個文件，所以只要進入「C：/oracle/odp.net/managed/common/Oracle.ManagedDataAccess.dll」，右鍵單擊它，並選擇「常規」下的「屬性」，選中「取消阻止」複選框（位於底部），然後單擊「應用」，然後單擊「確定」按鈕。

我在我的Windows 10中遇到了完全相同的問題，經過各種嘗試後，終於解決了這個問題。
