Can Oracle Client 11.2.0.2.0 work with an Oracle 12c Database?

I have a perl script running SQLLoader which was working before the DB upgrade. Yes, I could upgrade the client but that involves more env touching that I want to do at the moment.  Any experience with this issue?

I dont get a .bad file, I dont get and error.. it just doesnt do anything.

Yes, it will work.  Oracle clients will work with current version as well as with three newer versions and three older versions.  Below is product support matrix link:

I agree that there should be no reason 11g sqlloader would not connect to a 12c database.

I'm not sure about the hard and fast three versions...


What happens if you run sqlldr from a command prompt?

Maybe Perl is trapping the actual errors.
I'm starting to think it's just a bad install in the VM we spun up.  I have now been able to hit the DB with a 10 client from a different server.  Thanks
