Ocfs2-2.6.9-42.EL-1.2.4-2.i686.rpm requires Kernel 2.6.9-42.EL (kernel upgrade rpm for 2.6.9-42. ELsmp could not be found so I had to find an EL handle)
 
First find the kernel-2.6.9-42.EL.i686.rpm on the internet, mkinitrd-4.2.1.6-1.i386.rpm these two rpm,
1. Update mkinitrd
Delete mkinitrd-4.1.18
[Root@www.linuxidc.com for oracle] # rpm-e -- nodeps mkinitrd-4.1.18-2
Install mkinitrd-4.2.1.6
 
[Root@www.linuxidc.com oracle] # rpm-ivh mkinitrd-4.2.1.6-1.i386.rpm

2. Install the kernel-2.6.9-42.EL Kernel
Backup/boot
Root@www.linuxidc.com ~ # Cp-R/boot. old
[Root@www.linuxidc.com oracle] # rpm-ivh kernel-2.6.9-42.EL.i686.rpm

3. Edit grub. conf.

[Root@www.linuxidc.com oracle] # cd/boot/grub

[Root@www.linuxidc.com grub] # vi grub. conf

# Grub. conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a/boot partition. This means that
# All kernel and initrd paths are relative to/boot/, eg.
# Root (hd0, 0)
# Kernel/vmlinuz-version ro root =/dev/VolGroup00/LogVol00
# Initrd-version.img/initrd
# Boot =/dev/sda
# Default = 1
Default = 0
