Answer 1

show the output of tnsping command, using that you can find your corresponding sqlnet.ora file location for your database.
example:-
C:\Windows\System32>tnsping DEMODB
TNS Ping Utility for 32-bit Windows: Version 10.2.0.3.0 - Production on 12-AUG-2

Used parameter files:
D:\oracle\product\10.2.0\db_2\network\admin\sqlnet.ora
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = xxxxxxxx)(PORT = 1522)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = demodb)))
OK (60 msec)
