As of today, 220.127.116.11 is not released. It is planned to be released in 2nd half of calendar year 2014.
Reference: Release Schedule of Current Database Releases (Doc ID 742060.1)
I raised an SR to ask if 18.104.22.168 will be supported on Windows 2012 R2,
I have just been told today by oracle support that 11gr2 is planned to be certified on Windows 2012 R2.
"Oracle has plan to certify, the dates not yet confirmed" ( I quote ).
Could you clarify please ?
Oracle is not planning to certify 22.214.171.124 on Windows 2012 R2.
Only 126.96.36.199 or higher is only planned.
