Clusterware Installation fails at the end of CRS on Red Hat Linux 5

Problem Description
While installing oracle clusterware on Red Hat Enterprise Linux 5.0 at then end of the installation of Cluster Ready Services OUI prompts for the $CRS_HOME/root.sh script to be run on all
of the nodes in the cluster. The fact is when the root.sh script is run on the last node in
the cluster, the script calls the VIPCA utility which fails in RHEL 5. The same failure occurs on Red Hat Enterprise Linux 5.0, and SUSE Linux Enterprise Linux 10.

Solution of The Problem
As a workaround to solve the problem before running the root.sh script on the last node in the cluster,
alter the $CRS_HOME/bin/vipca script commenting out lines 119 through 123:

arch=’uname -m’
# if [ "$arch" = "i686" -o "$arch" = "ia64" -o "$arch" = "x86_64" ]
# then
# LD_ASSUME_KERNEL=2.4.19
# export LD_ASSUME_KERNEL
# fi

After commenting out run root.sh and it should be able to call VIPCA successfully.
But don't comment out the line 118 that is arch=’uname -m’ as it is needed by the root.sh script to set the arch variable.
