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

Hi Friends,

I installed 11.2.0.3 Grid Infrastructure software on Red Hat Enterprise Linux 6.3. After installation I executed root.sh script and got following error.

/oracle/grid11g/bin/clscfg.bin: error while loading shared libraries: libcap.so.1: cannot open shared object file: No such file or directory Failed to create keys in the OLR, rc = 127, Message:

Especially, you can get this error during execution of root.sh script on Linux 6.X

When I executed root.sh script, the output was below.

[root@dbtestvm1 ~]#  /oracle/grid11g/root.sh 
Performing root user operation for Oracle 11g

The following environment variables are set as: 
ORACLE_OWNER= ora11g 
ORACLE_HOME= /oracle/grid11g

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
The contents of “dbhome” have not changed. No need to overwrite. 
The contents of “oraenv” have not changed. No need to overwrite.

I checked libcap rpm is installed or not.

[root@dbtestvm1 ~]# rpm -q libcap 
libcap-2.16-5.5.el6.x86_64

H?mm libcap-2.16-5.5.el6.x86_64  is installed. The error message shows that it searches for libcap.so.1.  I configured YUM according to my article

I checked the availability of rpm files which contains libcap.

[root@dbtestvm1 ~]#  yum list | grep libcap 
libcap.i686 2.16-5.5.el6 @cd 
libcap.x86_64 2.16-5.5.el6 @anaconda-RedHatEnterpriseLinux-201206132210.x86_64/6.3 
libcap-devel.x86_64 2.16-5.5.el6 @cd 
libcap-ng.x86_64 0.6.4-3.el6_0.1 @anaconda-RedHatEnterpriseLinux-201206132210.x86_64/6.3 
libcap-ng-devel.x86_64 0.6.4-3.el6_0.1 @anaconda-RedHatEnterpriseLinux-201206132210.x86_64/6.3 
compat-libcap1.i686 1.10-1 cd 
compat-libcap1.x86_64 1.10-1 cd 
libcap-devel.i686 2.16-5.5.el6 cd 
libcap-ng.i686 0.6.4-3.el6_0.1 cd 
libcap-ng-devel.i686 0.6.4-3.el6_0.1 cd

So I need to install compat-libcap1.x86_64 rpm rpm. (My operating system is x86_64)

Complete!

Now, we can continue. Before rerunning of root.sh script, we must deconfigure it.

[root@dbtestvm1 ~]#  /oracle/grid11g/crs/install/roothas.pl -deconfig -force

let’s rerun root.sh script. It will run successfully.
