A number of customers have reported issues with 'smpatch' / Update Manager resulting from the recent migration to the My Oracle Support (MOS) infrastructure.
My colleagues BethB, PeterM, and EthanR have published Document 1288579.1 which explains what to do if you are unable to register systems & download patches via sconadm, smpatch, and Update Manager . This document is also accessible via the Oracle Sun OS Community page too.
I apologize most sincerely for any inconvenience caused.
