Oracle Linux 6 Update 4 ships with two sets of kernel packages:
Unbreakable Enterprise Kernel Release 2 (
kernel-uek-2.6.39-400.17.1.el6uek
)Red Hat Compatible Kernel (
kernel-2.6.32-358.el6
)
By default, both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel for the specific architecture (i386 or x86_64) are installed and the system boots the Unbreakable Enterprise Kernel.
To make your system use the Red Hat Compatible Kernel by default:
Edit
/etc/grub.conf
and change the value of thedefault
parameter to indicate the Red Hat Compatible Kernel. (Each entry for a bootable kernel in the file starts with atitle
definition. The entries are effectively numbered from 0 upwards, where 0 corresponds to the first entry in the file, 1 to the second entry, and so on. To view the GRUB manual, use the info grub command.)Edit
/etc/sysconfig/kernel
and change the setting for the default kernel package type fromDEFAULTKERNEL=kernel-uek
toDEFAULTKERNEL=kernel
.
