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 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 the LDAP directory server is

'TNS aliases' or 'service names' are defined locally to each workstation. Thus different workstations could have a completely different alias to refer to the same database. SolutionCheck what aliases or service names are defined on the workstation and specify that value http://web.synametrics.com/oratns.htm in the ODBC DSN. An invalid or non-existent name will result in this error. The following methods can be used to view existing TNS Service names on your machine: Look in the file 'ORANT\Network\Admin\Tnsnames.ora' (for versions of Oracle prior to 8.1) or 'Oracle\Ora81\ Network\Admin\Tnsnames.ora' (for versions of Oracle from 8.1 onwards). In this file each defined name will normally have ".world" appended to it.For Oracle 8, run "Oracle Net8 Easy Config". This will list the available service names.For Oracle 7, run "SQL Net Easy Configuration". This provides the option to list the available service names.For Oracle 8.1 onwards: Try specifying the full service name, i.e. as it appears in the tnsnames file. User commentsPosted by Ed Giarrusso on 1/19/11 10:18 AMWe had this problem after completing a default on a 2008 x64 server. ODBC connectivity test passed but WinSQL would fail to connect using the same ODBC. To resolve this problem I uninstalled and reinstalled to a folder that did not have the (x86) in the path.

Article: 00951 Last Reviewed: 7th September 2006 Revision: 1 This error indicates that Oracle is unable to locate the service name specified http://www.easysoft.com/support/kb/kb00951.html in your Easysoft ODBC-Oracle Driver ODBC data source. You need to check 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/ the Database attribute value in the data source.If you are using the standard Oracle client, the Database attribute value must specify a valid service name defined in tnsnames.ora. For example, for the following tnsnames.ora entry, the Database attribute value needs to be my_database: my_database = (DESCRIPTION = (ADDRESS = (PROTOCOL = could not TCP)(HOST = my_host)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = my_database) ) ) If you are using the Instant Client without a tnsnames.ora file, the Database attribute value needs to be a SQL connect URL rather than a service name: //host:port/service_name where host is the host name or IP address of the Oracle database server, port is the Oracle listener port could not resolve and service_name is the service name. 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.

while creating a linked server to Oracle ★★★★★★★★★★★★★★★ SnehadeepJune 30, 201028 0 0 0 This is one of the most common errors while creating linked server to Oracle database. Today I will discuss the reason for this error and possible resolutions.
Full error message: OLE DB provider "MSDAORA" for linked server "LINKED_ORA" returned message "ORA-12154: TNS:could not resolve 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 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 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. 1. Verify that the tnsnames.ora file has the alias and the service name that the customer is using.
