How to install 11.2.0.4

Hi All,

Am little confused about installing 11.2.0.4 on Windows 2008 R2 server.

Is that i need to install 11.2.0.1 base release and then install 11.2.0.4 on top of that or i can directly install 11.2.0.4

I believe, we had option in 11.2.0.3 that we can directly install without 11.2.0.1.

I searched metalink notes, but none doesnt say about this.

Also, i see there are 7 files part of 11.2.0.4, but not sure which one are database software.

Appreciate if anybody can share some details on this

Thanks in advance
