Welcome to StackOverflow!

From the Doc. If tnsnames.ora isn't being used.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': '(DESCRIPTION=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS_LIST=(ADDRESS=(COMMUNITY=XXX.xxxx)(PROTOCOL=TCP)(Host=xxx-xx.xxx.com)(Port=1521)))(CONNECT_DATA=(service_name=xxxx.xxxxx)))',
        'USER': 'a_user',
        'PASSWORD': 'a_password',
        'HOST': '',
        'PORT': '',
    }
}

Or you have made sure your oracle client has tnsnames configured

tnsnames.ora

MY_AWESOME_TNS_ALIAS=(DESCRIPTION=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS_LIST=(ADDRESS=(COMMUNITY=XXX.xxxx)(PROTOCOL=TCP)(Host=xxx-xx.xxx.com)(Port=1521)))(CONNECT_DATA=(service_name=xxxx.xxxxx)))

Now django can be configured by alias name. You hide the connection-details from the django application.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.oracle',
        'NAME': 'MY_AWESOME_TNS_ALIAS',
        'USER': 'a_user',
        'PASSWORD': 'a_password',
        'HOST': '',
        'PORT': '',
    }
} 

Best of luck!
