I had a look into my documentation and found the following:
Cause: This message occurs usually because the SQL*Net driver is not loaded
into memory or there is a mismatch of the version of the driver. A user
program linked with an obsolete library may also cause this message. Only
programs provided by Oracle Corporation should use this interface.
I should try to reinstall SQL*Net, and try again.
Keep me updated of the proceedings...
