问题
I am trying to connect to an Oracle DB through the Oracle Provider for OLE DB in SSIS, but am getting the following error when testing the connection: "tns listener was not given the service_name in connect_data". I am not too familiar with Oracle, so could someone provide me some direction for how to fix this error?
回答1:
You can add the service name after the host name with a forward slash between them. This has worked in both the Microsoft and Oracle OLE DB providers.
IP/Service_Name also works, "12.12.123.123/Server1.domain.com"
回答2:
First of all, always use Oracle driver. Not the Microsoft one.
Then, when connecting, supply the TNSNAME, USERNAME and PASSWORD to a OLEDB Connection.
That's all!

Ok ok, been here, and this is what works:
You need oracle data access components http://www.oracle.com/technetwork/topics/dotnet/utilsoft-086879.html
Download the one that applies to you (11g, 12c...) It installs an OLE DB provider which is FAST and also .NET connectors (wich also work really well), so I recommend using OLEDB (also, attunity connector works wonders aswell after you installed ODAC).
Then just connect using ip/service name + credentials, for example

You need to type "Servername/ServiceName" to Server Name Field .
