Oracle.DataAccess.Client错误

Question

背景:本网站使用oracle和spring.net.
版本的Oracle.DataAccess:4.112.2.0
版本的Spring:1.3.2.40943

Webconfig文件

<db:provider id="SDDbProvider" provider="Oracle.DataAccess.Client"
           connectionString="User Id=****; Password = *****; Data Source = (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=****)(PORT=****))(CONNECT_DATA=(SERVER=dedicated)(SERVICE_NAME=*****)))" />

这在调试模式下工作正常.我在本地IIS(7.5)上发布了这个网站,并且工作正常.但是,当我将发布的文件夹复制到远程服务器(也运行IIS 7.5)时,它会给出以下错误信息.

注意:我检查了已发布文件夹中的bin,它具有Oracle所需的所有DLL

知道为什么会这样吗？它与远程服务器中的GAC有关吗？谢谢

我猜了一周后我解决了这个问题.想分享我的经验.

首先,此错误消息与Spring框架有关.基于该DBprovider我们在我们的配置文件指定(在我的情况下,它Oracle.DataAccess.Client),Spring.Data DLL尝试解析数据库提供商.(有关Spring dbproviders的更多信息)

它使用资源文件(Spring.Data.Common.dbproviders.xml)来解决此问题.从dbproviders.xml文件中的以下行抛出错误.(文件位置:Spring.Net/src/Spring/Spring.Data/Data/Common/dbproviders.xml)

 <constructor-arg name="connectionType" value="Oracle.DataAccess.Client.OracleConnection, Oracle.DataAccess, Version=2.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342"/>

由于某种原因,dbproviders.xml尝试在GAC(windows/assembly/GAC)中找到Oracle.DataAccess DLL.根据我的经验,它不会在bin文件夹中查找.如果它无法在GAC中找到DLL,则会抛出上述错误消息.所以我使用GACUtil在GAC中安装了Oracle.DataAccess(版本2.102.4.0)DLL.我认为它也看起来是dbproviders.xml中指定的版本.(如果我错了,请随时在这里发表评论)

这是针对Spring框架的.但是,为了工作NHibernate你应该在你的BIN文件夹中有Oracle.DataAccess DLL(否则它会抛出" 提供程序与oracle客户端的版本不兼容 "错误)和相关的oracle即时客户端在同一位置(否则它会抛出" 无法加载文件或程序集"Oracle.DataAccess"或其中一个依赖项.尝试加载格式不正确的程序."错误).

如果你使用oracle即时客户端,你不必在机器上安装oracle客户端(很确定每个人都知道它).在我的bin文件夹中,我放了Oracle.DataAccess(版本4.112.2.0)和即时客户端DLL(如问题中所述).我使用版本4.112.2.0因为我找不到版本2.102.4.0的即时客户端DLL.(我知道这是一团糟,但它是如何工作的)

所以现在一切正常.

小提示:如果有人想在远程服务器中使用GacUtil并且不想安装.net framework SDK,请将gacutil.exe和gacutil.exe.config文件复制到远程服务器并从那里运行.确保使用version ="v2.0.50727".如果您使用version ="v4.0.30319",那么它会将DLL添加到C:\ Windows\Microsoft.NET\assembly而不是C:\ Windows\assembly.
