Hi, I do have client currently using Oracle 11.2.0.3 on windows 2008R2 server, they are planning upgrade their server to Windows 2012 R2. I did check with google and found only 11.2.0.4.14 or later support Windows 2012 R2. My question is can my client using 11.2.0.4 instead 11.2.0.4.14? If not, where can they download all the patch from 11.2.0.4.1 to 11.2.0.4.14?
