Puh ... I've got many mails over several months asking about the current status of certification of SuSE SLES12 for Oracle Database 12.1.0.2 . It took a while - and I believe it was not in our hands. But anyhow ... finally ...
SuSE Enterprise linux SLES12 is now certified with Oracle Database 12.1.0.2A quick check on MOS showed that it may take a few additional hours or days until this information is displayed. And the certification for Oracle 11.2.0.4 is underway as well but may take a few extra weeks. Be patient please.
I had a SuSE Linux running on my previous laptop as dual-boot for quite a while. And I still like SuSE way more than any other Linux distributions potentially because of the fact that it was the Linux I started developing some basic Unix skills. I picked up my first Linux at the S.u.S.E. "headquarters" near Fürth Hauptbahnhof in 1994. I used to live just a few kilometers away and the version 0.9 a friend had given to me on a bunch of 3.5'' floppies had a disk failure. I believe the entire package did cost DM 19,90 by then - today roughly 10 Euro when you don't consider inflation - and was distributed on floppy disks. The reason for me to buy it was simply that I had no clue about Linux - but SuSE had a book delivered with the distribution.
This is a distribution I had purchased later on as well - they've had good discounts for students by then.
