I like Upgrade Workshops for a very different reason:
Hopefully people feed back with questions and information I wasn't aware off before. So for myself these workshops are also a learning experience. And thanks to a customer in Singapore (Thanks a lot, Hanh!!) I learned something about Oracle's Bundle Patches for MS Windows.
Customer asked about a specific issue when using RMAN Duplicate command in 12c failing with a nice ORA-600 [KSRPCSEXEC_1]. This got logged a while ago as bug16883554 - and it will be fixed in database patch set 220.127.116.11. But this customer asked for an earlier delivery.
So after a quick check of the SR and the bug it was clear that this patch will be also included for the MS Windows platform into the Bundle Patch 18.104.22.168.4 on Win.
Well, my first thought: Ouch! That will be the July 2014 PSU.
But in fact it isn't meant here. So I learned that on Windows patching runs on a different schedule and notation.
