标签： c# asp.net mono oracle11g

我是linux ubuntu和mono运行时的新手我尝试连接到oracle 11G，就像通常在windows 中一样（我在Windows中用System.Data.OracleClient和Oracle.OracleClient试了一下，两者都工作正常）< /强> 但 我在ubuntu中遇到这个问题： System.DllNotFoundException：libclntsh.so 这是堆栈跟踪：

    libclntsh.so

Description: HTTP 500. Error processing request.

Stack Trace:

这是我连接到oracle的连接字符串我使用的是System.data.oracleclient 

string oradb = "Data Source=(DESCRIPTION="
                        + "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))"
                        + "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)));"
                        + "User Id=hr;Password=hr;";
            OracleConnection conn = new OracleConnection(oradb);
            conn.Open();
            OracleCommand command=new OracleCommand();
            command.Connection=conn;
            command.CommandText="select * from employee";
            OracleDataReader reader=command.ExecuteReader();
            while(reader.Read())
            {
                Response.Write(reader[0]+"<br>");
            }
            conn.Close();
            command=null;
            reader.Close();
            reader=null;

您需要安装OCI，per the documentation。另外，请记住不再支持Oracle Data Client（在Mono和Microsoft .NET中），所以最安全的选择是use a commercial provider。你已经为这个数据库支付了几笔资金，几百个人有什么不同？

更新，因为原来的答案是2岁。

只需使用Oracle的托管驱动程序即可。你只需要它，没有别的。然后，您可以直接使用简单的连接字符串连接到数据库。

<system.data>
  <DbProviderFactories>
    <remove invariant="Oracle.ManagedDataAccess.Client" />
    <!-- If any should be in the machine.config -->
    <add name="Oracle Data Provider for .NET" invariant="Oracle.ManagedDataAccess.Client" description="Oracle Data Provider for .NET" type="Oracle.ManagedDataAccess.Client.OracleClientFactory, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral" />
  </DbProviderFactories>
</system.data>
<connectionStrings>
  <clear />
  <add name="OracleContext" providerName="Oracle.ManagedDataAccess.Client" connectionString="DATA SOURCE=<IP_ADDRESS>:1521/XE;PASSWORD=<PASSWORD>;USER ID=<USER_ID>;Connection Timeout=600;Validate Connection=true" />
</connectionStrings>

我使用ServiceStack的OrmLite作为ORM，但如果您不想使用ORM或其他任何东西，它也可以直接使用。您需要确保的是，您的ORM库也使用托管驱动程序而不是旧驱动程序。我写了一篇关于黑客的博客文章，我不得不更改ServiceStack.OrmLite.Oracle以使用新的托管驱动程序。这解决了我所有的问题。
