Impossible de se connecter à la base de données Oracle avec Django sur Ubuntu

Question

Chaque fois que je tente d'exécuter une commande comme python manage.py syncdb, je reçois l'erreur suivante:

 
Traceback (most recent call last):

Est-ce résoluble sur Ubuntu?

Answer 1

essayer easy_install cx_Oracle, il compilera module cx_Oracle de la source

Answer 2

Pour commencer - est-ce vraiment un problème Django, ou tout simplement un problème de cx_Oracle? Cx_Oracle est-il correctement installé? Pouvez-vous vous connecter à votre base de données Oracle dans une session shell Python?

import cx_Oracle 
conn = cx_Oracle.connect('/') # user/password@dsn 
cursor = conn.cursor() 

Si cela ne déclenche pas d'exception, vous vous êtes connecté avec succès.

Answer 3

Vous devez installer à la fois cx_Oracle et un client Oracle.

cx_Oracle peut être found here.

Un client Oracle approprié peut être found here.

Vous devrez également définir la variable LD_LIBRARY_PATH avant de démarrer votre application. Cela peut être fait (par exemple):

export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib 

Maintenant, vous devriez être en mesure de passer le message d'erreur de cx_Oracle.
