Hi Eduardo,

I haven't found anything specific to the Oracle 12 driver that could prevent it from working, but with that said, it's possible that some drivers might not be working with the database plugin, as we cannot always guarantee compatibility with all drivers. See if you can find other drivers for Oracle 12, make sure it's a 32 bits driver as well. Of course, make sure that your connection string has the proper user and password, and that you haven't made any typo.

Feel free to contact Technical Support if you want further investigation on this issue.

Regards,
