How to Connect Airflow to oracle database

Question

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

You have a problem in your connection settings, either your setting is not loading properly to the oracle hook or you are missing a python package that save/load your connection settings. You can test it by hard coding your credentials.

https://github.com/airbnb/airflow/blob/master/airflow/hooks/oracle_hook.py

conn = self.get_connection(self.oracle_conn_id)
dsn = conn.extra_dejson.get('dsn', None)
sid = conn.extra_dejson.get('sid', None)
service_name = conn.extra_dejson.get('service_name', None)
if dsn and sid and not service_name:
    dsn = cx_Oracle.makedsn(dsn, conn.port, sid)
    conn = cx_Oracle.connect(conn.login, conn.password, dsn=dsn)
elif dsn and service_name and not sid:
    dsn = cx_Oracle.makedsn(dsn, conn.port, service_name=service_name)
    conn = cx_Oracle.connect(conn.login, conn.password, dsn=dsn)
else:
    conn = cx_Oracle.connect(conn.login, conn.password, conn.host)
