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.

Action: - If you are using local naming (TNSNAMES.ORA file): - Make sure that "TNSNAMES" is listed as one of the values of the NAMES.DIRECTORY_PATH parameter in the Oracle Net profile (SQLNET.ORA) - Verify that a TNSNAMES.ORA file exists and is in the proper directory and is accessible. - Check that the net service name used as the connect identifier exists in the TNSNAMES.ORA file. - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA file. Look for unmatched parentheses or stray characters. Errors in a TNSNAMES.ORA file may make it unusable. - If you are using directory naming: - Verify that "LDAP" is listed as one of the values of the NAMES.DIRETORY_PATH parameter in the Oracle Net profile (SQLNET.ORA). - Verify that the LDAP directory server is up and that it is accessible. - Verify that the net service name or database name used as the connect identifier is configured in the directory. - Verify that the default context being used is correct by specifying a fully qualified net s

Full error message: OLE DB provider "MSDAORA" for linked server "LINKED_ORA" returned message "ORA-12154: TNS:could not resolve error 12154 received logging on to the standby rac the connect identifier specified". Msg 7303, Level 16, State 1, Line 1 Cannot initialize the data source object of OLE DB provider "MSDAORA" for linked server "LINKED_ORA". First https://docs.oracle.com/cd/B19306_01/server.102/b14219/net12150.htm of all make sure 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 https://blogs.msdn.microsoft.com/dataaccesstechnologies/2010/06/30/ora-12154-tns-could-not-resolve-the-connect-identifier-specified-error-while-creating-a-linked-server-to-oracle/ bit then we need to install 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.
