Yes, we were. When I was working for MMS last year I was playing with a 4.3.1 system (can't remember if 4.3.1.2 or 4.3.1.1) under Solaris 8 and Mincom TP. I was playing around with Oracle 7 and Oracle 8 for a database conversion test I was doing at the time. It was never in production but I did get a system up and running on both Datbase version on a Sun Ultra 5.
But, for best protection, I'd suggest speaking with the Mincom Help Desk closest to you (you don't say where you're from) and have them certify it against the folks in Brisnbane. Keep in mind I don't think that Mincom TP is supported any more and I never played with it with Tuxedo.
