Answer 1

from the primary; look athe parameter log_archive_dest_x you'll see something like:
SQL> select name, value from v$parameter where name like '%log_ar%' ;
log_archive_dest_2
SERVICE=TEST_STANDBY LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_
UNIQUE_NAME=test DELAY=120
tnsping TEST_STANDBY and here is your standby.
From the standby; query if fal_server is configured:
SQL> select name, value from v$parameter where name='fal_server';
NAME VALUE
fal_server TESTPROD
tnsping TESTPROD and here is your primary.
