Oracle Enterprise Edition Database on on Linux x86-64 on RHEL 5.2

Hi gurus,

My requirement is to install Oracle Enterprise Database 11.2.0.2 on RHEL 5.2 Linux x86-64(bit).   I am good with OS requiments and every other thing.  The only question I have is which software I have to download to do it.

I am seeing right now at oracle.com --> Downloads.  I am seeing the following:

(11.2.0.2.0)

zLinux64                    File 1, File2 (2GB) See All

(10.2.0.1.0)

under this many operating systems.  Among them

Linux x86-64    File 1, File 2 (2 GB)

My question is do I need zLinux64(11.2.0.2.0) to download ?  the word zLinux is confusing me.

or

download (10.2.0.1.0) Linux x86-64 and apply some patch to make it 10.2.0.2.0) ?
