error while loading shared libraries: libcap.so.1: cannot open shared object file:

When I was installing single instance  ASM (grid infrastructure) Software .I came across with following error while running root.sh .

[root@dg2 ~]# /u01/app/11.2.0/grid/root.sh

Failed to create keys in the OLR, rc = 32512, 32512
OLR configuration failed
 
For that what i did was.It is required to install  relevant rpm which  provides above libcap.so.

 * compat-libcap1-1.10-1.x86_64
 * compat-libcap1-1.10-1.i386
 * libcap-*

yum install compat-libcap1-1.10-1.i386
yum install  compat-libcap1-1.10-1.x86_64 
yum install  libcap-* 

After this you may want to run root.sh again. Befor this you may want to deconfigure the instance configuration.


$GRID_HOME\crs\install\rootcrs.pl -deconfig  -force -verbose 
$GRID_HOME\crs\install\roothas.pl -deconfig  -force -verbose

 [root@dg2 install]# ./roothas.pl -deconfig -force -verbose
