[Solved] Oracle TNSPING Resolve Name Error (TNS-03505)

Scenario: Issue while connecting to SYS schema in a newly installed database from SQL Developer. So we tried to TNSPING the ORCL connection and we faced a 'failed to resolve name' error as below,

Failed to Resolve Name.

Cause: The issue is because we had both Oracle DB Home and Client installed. The tnsnames.ora file was present only in the network/admin folder in DB_Home and not in Client/network/admin 

Resolution: Copy the tnsnames.ora file and paste a copy to the network/admin folder in client installed directory. Try again as below and connection will be fine.

Error resolved.
