Erreur 28545 dblink oracle > mariadb
Bonjour à tous,
J’essaie de mettre en place la fonction dblink entre une base Oracle 10.2.0.4. et un mariadb 10 sur un environ Redhat 5 (oui c'est pas récent).
J'ai suivi cette doc http://www.dbasupports.com/2014/01/c...r-through.html mais au lieu de passer dg4odbc j'utilise hsodbc.
La connexion avec isql depuis mon serveur oracle vers la base mysql est ok, le tnsping est ok mais lorsque je souhaite faire un select depuis sqlplus vers mariadb j'obtiens l'erreur

Je ne suis pas très à l'aise avec Oracle et je n'arrive pas à trouver la cause du problème.
Si vous avez une piste je suis preneur :)
Merci.
