oracle - NHibernate 2.1 和 Oracle 10g 客户端出错

Question

我需要让 NHibernate 2.1 与 oracle 数据库对话。我需要使用 Oracle 10g 客户端。尝试构建 session 工厂时出现以下错误:

Unable to cast object of type 'Oracle.DataAccess.Client.OracleConnection' to type 'System.Data.Common.DbConnection'.

我不记得在 NHibernate 2.01 中遇到过这个错误。我试图让服务器管理员安装 11g 客户端，但看起来这是一场失败的战斗。

以下是我的 web.config 中的重要部分:

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <qualifyAssembly partialName="Oracle.DataAccess" fullName="Oracle.DataAccess, Version=10.2.0.100, Culture=Neutral, PublicKeyToken=89b483f429c47342"/>    
  </assemblyBinding>
</runtime>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
 <session-factory>
   <property name="dialect">NHibernate.Dialect.Oracle10gDialect</property>
   <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
   <property name="connection.driver_class">NHibernate.Driver.OracleDataClientDriver</property>
   <property name="connection.connection_string_name">Demo</property>
   <property name="show_sql">false</property>
   <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
  </session-factory>
</hibernate-configuration>

我在 NHUsers 组中问了同样的问题，并得到了可以接受的答案。
将以下内容添加到休眠配置中:

<property name="hbm2ddl.keywords">none</property>
