Oracle uses the IANA data. It’s currently only Microsoft that doesn’t – at least not everywhere.
I think HP-UX is in a similar boat. That is, although HP-UX uses the IANA tz data, it also has a proprietary time zone database called tztab, originally developed independently from the tz project. As I understand things, HP continues to maintain tztab for backward-compatibility reasons, and there are mappings between tztab and tz names.
