The title of the post is a question taken from a MOS Doc ID 1189783.1 named “Important Changes to Oracle Database Patch Sets Starting With 220.127.116.11”. Yes, the first patch set for 11gR2 is out for Linux x86 and x86-64 (patch number is 10098816). It’s 5G in size, BTW. There’s no patch set release notes, though. I’ll update the post when they become available.
Update 11-SEP: the patch is no longer available for downloading.
Update 13-SEP: the patch is now available.
Update 16-SEP: patch set release notes are now available
