I am trying to create a connection to an oracle db instance (oracle:thin) using Airflow.
According to their documentation I entered my hostname followed by port numb
this worked for me in extra field
{ "dsn":"192.168.x.x" , "service_name":"some.service.name" }
I get from https://github.com/apache/airflow/blob/master/airflow/hooks/oracle_hook.py#L49
