remote host. Action: Reestablish connection. 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. For example, if the type error while trying to retrieve text for error ora-12154 of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached. 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 t

ORA-28547: connection to server ora-12154 tns could not resolve service name oracle 11g failed, probable Oracle Net admin error tips Oracle Error Tips by Stephanie F. The Oracle docs note this on the ORA-28547 error: ORA-28547: connection to https://docs.oracle.com/cd/B19306_01/server.102/b14219/net12150.htm server failed, probable Oracle Net admin error Cause: A failure occurred during initialization of a network connection from a client process to the Oracle server: The connection was completed but a disconnect occurred while trying to perform protocol-specific initialization, usually due to use of different network protocols by opposite sides of the connection. http://www.dba-oracle.com/t_ora_28547_connection_to_server_failed_probable_oracle_net_admin_error.htm This usually is caused by incorrect Oracle Net administrative setup for database links or external procedure calls. The most frequent specific causes are: -- The connection uses a connect string which refers to a Heterogeneous Services agent instead of an Oracle server. -- The connection uses a connect string which includes an (HS=) specification. ********************************** Action: Check Oracle Net administration in the following ways: -- When using TNSNAMES.ORA or an Oracle Names server, make sure that the client connection to the ORACLE server uses the correct service name or SID. -- Check LISTENER.ORA on the connection end point"s host machine to assure that this service name or SID refers to the correct server. -- Confirm in TNSNAMES.ORA or the equivalent service definition that the connect string does NOT contain (HS=).

First of all make sure could not 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 64 could not resolve 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 service nhere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 6.2 million programmers, just like you, helping each other.
