Identify the differentiation between Oracle Enterprise Linux from Redhat Enterprise Linux

Identify the differentiation between Oracle Enterprise Linux from Redhat Enterprise Linux

We can differentiate the OEL from RHEL by checking below things

1. Kernel  - uname -mrs command

RHEL runs with normal Redhat Kernel
[root@nsk ~]# uname -mrs
Linux 3.10.0-693.5.2.el7.x86_64 x86_64

OEL runs with Unbreakable Enterprise Kernel
[root@testserver ~]# uname -mrs
Linux 3.8.13-118.16.2.el6uek.x86_64 x86_64

2.  Yum repositiry

RHEL points to  RHEL repo name (only 3)
ex: RHEL-7 - Base 
      RHEL-7 - Extras
      RHEL-7 - Updates

OEL points to Oracle repo name ( customized many repo)
ex: Oracle Linux 6Server Latest (x86_64)
      OL 6Server - x86_64

3. MTA

RHEL: comes with sendmail and postfix
OEL : supports sendmail as a preferred MTA

4. Patching

RHEL gets update from  RHN satellite server
OEL gets update from  Oracle Spacewalk server
