Knowledge Base -Grid Infrastructure Installation Failed with libcap.so.1

When I was installing Grid Infrastructure for Stand Alone Server  following script was to run

/u01/app/11.2.0/grid/root.sh

while running this following error was given.
error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory .

[root@asm3 /]# /u01/app/11.2.0/grid/root.sh

[root@asm3 /]#

Solution:-
For this error what i did was installed following rpms

[root@asm3 /]# yum install libcap.x86_64
[root@asm3 /]# yum install compat-libcap1.*
[root@asm3 /]#yum install compat-libcap2.*
[root@asm3 /]#yum install libcap*

 [root@asm3 /]# /u01/app//11.2.0/grid/crs/install/roothas.pl -deconfig
 [root@asm3 /]# rm /etc/oracle/olr.loc 

 Again you can run the script again

 [root@asm3 /]# /u01/app/11.2.0/grid/root.sh
