you have reviewed the following Microsoft KB article that has a lot of good information on troubleshooting Oracle linked server issues.
How to set up and troubleshoot a linked server to an Oracle database in SQL Server http://support.microsoft.com/kb/280106 Also make sure you have installed Oracle Client on the SQL server. If the SQL server is 64 bit then we need to install ora 12154 tns could not resolve service name 64 bit Oracle provider. You can also create linked server using Oracle ODBC driver together with Microsoft OLE DB provider for ODBC. Once again on a 64 bit SQL server you need to install the 64-Bit OLEDB Provider for ODBC (MSDASQL) and 64 bit Oracle ODBC drivers. However 64-Bit OLEDB Provider for ODBC (MSDASQL) is already there in Windows Vista/Windows Server 2008 and later OS. This particular error message is a very general error message and can happen for quite a number of reasons. For general understanding of the error, you can review oracle documentation like this http://ora-12154.ora-code.com/ In SQL Server Linked Server, it could indicate a few things (not limited to)– 1. SQL Server (and oracle net libraries) is not able to get the TNS alias from tnsnames.ora file. 2. Something is wrong with the way the alias is created in the tnsnames.ora file (incorrect syntax) 3. TNS alias could not be resolved into a connect descriptor Below is a list of things that you can try to resolve this issue. 1. Verify that the tnsnames.ora file has the alias and the serresolve the connect identifier specified"?

You need to check the Database attribute value in the data source.If you are using error ora 12560 the standard Oracle client, the Database attribute value must specify a valid service name defined in tnsnames.ora.

For example: //my_host:1521/my_database If you want to use the Instant Client with a tnsnames.ora file, the Database attribute value must specify a tnsnames.ora service name and you need to set and export the TNS_ADMIN environment variable. Set TNS_ADMIN to specify the location of the tnsnames.ora file.

I am on a project that is using oracle (which I rarely use) I need to create an ODBC connection so I can access the some data via MS Access I have a application on my machine called oraHome90. It seems to allow a configuration of something called a listener in a “net configuration utility”, I think that a “Local Net Service Name Configuration” needs to also be done. The IT support gave me this information to set up the ODBC connection . I have tried every combination that I can think of. I can get past a test that successfully passes a test to “login“ to the oracle server database. When I try to create the ODBC connection I get the following error: ORA-12154: TNS: Could not resolve service name. Assuming that I want to start from scratch and the following information is supposed to allow for me to connect to the database….. Any suggestions or comment ? Note: ultimately the project will have a website .ASP page query the data, but I have to first prove that I can see the data using the ODBC connection via MS Access Service name: SERVICENAME HOST = HOST.XYZi.com User Id: MYUSERID Password: MYPASSWORD ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 'Oracle Connection Dim ocst Dim oconn ocst = "Provider=OraOLEDB.Oracle;" & _ "Data Source=DATASOURCE;" & _ "User ID=CHIJXL;" & _ "Password=password;" set oconn = CreateObject("ADODB.Connection") oracle odbc tns share|improve this question edited Oct 15 '08 at 19:26 David Basarab 35.3k38105144 asked Oct 15 '08 at 19:23 Joe 4164811 add a comment| 19 Answers 19 active oldest votes up vote 8 down vote from http://ora-12154.ora-code.com ORA-12154: TNS:could not resolve the connect identifier specified Cause: A connection to a database or other service was requested using a connect identifier, and the connect identifier specified could not be resolved into a connect descriptor using one of the naming methods configured.
