I have a WinForms program that connects to an Oracle database server using deprecated System.Data.OracleClient. When I try installing that program on another computer, this program is trying to use SID's from that is defined in the tnsnames.ora file, but can't find the file.
Where do I put the tnsnames.ora file so that it is visible to the program?
If you have the oracle client installed, use the tnsping command from a cmd promt. the path of tnsname file will appear
