Toad - ORA-12154: TNS:could no resolve the connect identifier specified

Atakan CosgunerOct 15 2022

Hello,
I have successfully installed Oracle on the Linux operating system. I got an error when I tried to connect with Toad. The error stated that the tnsnames.ora file does not exist. I copied the tnsnames.ora file from the /u01/app/oracle/product/19.3.0/dbhome_1/network/admin file path in the Linux Oracle database to the C:\oracle\instantclient file path on the Windows computer where Toad is installed. I am currently getting the error in the picture. Can anyone help for this error?
Thank you.
