While running root.sh , we got below error , after little bit of googling I found that we need more packages
Note:  there was no error reported regarding missing packages

What I found that we have these two packages installed 

[root@host dev]# yum list installed | grep -i libcap

Unable to read consumer identity

libcap.x86_64                      2.16-5.5.el6         @anaconda-RedHatEnterpriseLinux-201206132210.x86_64/6.3

I went ahead and installed these two packages and root.sh went fine.

[root@host dev]# yum install compat-libcap1.i686

[root@host dev]# yum install compat-libcap1.x86_64 -y

[root@host dev]# yum list installed | grep -i libcap
