Django Connection Error(Oracle 11g Database)

Hi, Guys.
When my django program connected to Oracle 11g DB, an error occured.
When I input “python manage.py migrate” command, a below error occured.
When my django connected to sqlite3 DB, no problem.
How do I solve it?

Django 1.11.22
cx-Oracle 7.2.2
python 3.6
Oracle 11g

Error Message.
