Test Connection Within ODBC Administrator With 11.2 Fails With ORA-12154 When TNS_ADMIN References a Network Drive

(Doc ID 1177343.1)

Last updated on MAY 30, 2017

Applies to:

Oracle ODBC Driver - Version 11.2.0.1 and later
Microsoft Windows (32-bit)
Microsoft Windows x64 (64-bit)

Symptoms

Testing a connection using the ODBC admin tool with 11.2 fails with ORA-12154 when referencing network configuration files on a network resource. The TNS Server name pick list is empty and is not populated. Generic connectivity is successful with tnsping and SQL Plus. Saving the DSN with a valid alias and connecting from a UDL file, vbs script or other ODBC application connects fine. This is a specific issue with the code within the Test Connection button.

Changes

Upgraded the driver to 11.2 on Windows 7 or Windows 2008R2.
