I have installed Toad for Oracle 12.5 (32 bit) but unable to connect Database. I have recieved the error unable to resolve TNS names. Toad is detecting my TNS file but still giving the above netioned error
in command prompt execute:
(where xxx is your tns entry that point to some instance).
Please the result of whole operation (from top to bottom) here.
As Damir Suggested it is the Only Way of Knowing the Issue and
else better to import which is similar to TNS File names Ora
