Oracle - tnsping - Message 3513 not found; product=NETWORK; facility=TNS
Read OriginalThis technical article details troubleshooting an Oracle database connectivity issue on Windows XP. After installing Oracle 11.2 XE alongside an existing 11.1 client, the author encountered the obscure 'Message 3513 not found' error with tnsping and ODBC failures. The solution involved analyzing the system PATH variable, which was invoking 11.2 binaries before 11.1 client binaries, and fixing it by reordering the PATH entries.
