在ASP.NET上使用Oracle Instant Client。出现ORA-12154或12545错误

Question

我有一个已部署的Web服务，并且正在bin文件夹中使用Oracle Instant Client实例。问题是，无论我在测试服务器上使用什么连接字符串，都会出现ORA-12154错误或ORA-12545错误。

这是我尝试过的连接字符串： 通用标签

我尝试在系统中设置TNS_ADMIN变量，但这对我没有任何帮助。当然，在我的机器上一切正常。只是不在部署的服务器上。

you may have already solved this issue but did you do the following

1. Download the ODAC xcopy version
   • http://www.oracle.com/technetwork/database/windows/downloads/utilsoft-087491.html

2. Copy the following dll’s from the ODAC folder to either the bin (if web) or location of the exe file

   • oci.dll (Client Code Library)
   • ociw32.dll
   • Oracle.DataAccess.dll
   • orannzsbb11.dll (Security Library)
   • oraocci11.dll (OCCI Library)
   • oraociei11.dll (OCI Instant Client Data shared Library)
   • OraOps11w.dll

3. I created a blog post that walks though the steps along with a link to a sample application.
