In addition to installing the software on the node where you
initiated the installation, the installed directory structure is copied to every node on the cluster,
or to a shared disk location if you are using a file system such as OCFS2 for the shared Oracle
binaries.

After installation is complete, you are prompted to run two scripts as root on each node of the
cluster:
/u01/app/oraInventory/orainstRoot.sh
/u01/app/11.1.0/crs/root.sh
Here is the output from running the commands on the first node:
[root@oc1 ~]# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory to 770.
Changing groupname of /u01/app/oraInventory to oinstall.
