uname -a on my server show me 2.6.32-200.13.1.el5uek, that mean that it's a Entreprise Linux 5 ?
what the diff betwenn OEL5, OEL6 EL5UEK, EL6UEK, i'm lost.There is no OEL, just OL. :) Oracle Linux 5 (OL5) and Oracle Linux 6 (OL6) are completely different major versions of Oracle Linux. Each of those has two kernels, the Red Hat Compatible Kernel (RHCK) or the Unbreakable Enterprise Kernel (UEK).
Oracle Linux kernel appear as UEK ?Yes.
I just go to edelivery and found theses download :This is the complete install DVD, which includes both the RHCK and UEK as well as most of the packages available for OL6.
1) Oracle Linux Release 6 Update 4 for x86_64 (64 Bit) V37084-01 3.5G
2) Oracle Linux Release 6 Update 4 Boot iso image for x86_64 (64 bit) V37088-01 197MThis is a small bootable image that uses the RHCK during install but only contains the installation program, but none of the packages. You need to have the contents of the ISO from (1) available somewhere on your network.
3) Oracle Linux Release 6 Update 4 UEK Boot ISO image for x86_64 (64 bit) V37090-01 196MThis is a small bootable image that uses the UEK Release 2 kernel during install but only contains the installation program, but none of the packages. You need to have the contents of the ISO from (1) available somewhere on your network. This image also has btrfs support during installation, something that (1) and (2) do not.
If I build a server with the 1) what will be the result of a uname -a ?The default kernel is 2.6.39-400.17.1.el6uek, but it will also install the RHCK 2.6.32-358.el6.
Perhaps it might be worth adding that Oracle Enterprise Linux (OEL) was re-branded to Oracle Linux (OL) in October 2010 during release version 5.5, which introduced the Unbreakable Enterprise Kernel (UEK).
I sometimes wonder though if the UEK kernel was the reason for the renaming of the product, in particular since previous versions were also renamed.
