[EN] Run root.sh from a directory that has read/execute access to the grid owner 'oracle'

Problem:
To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user:
/oracle/app/oracle/product/11.2.0/grid/perl/bin/perl -I/oracle/app/oracle/product/11.2.0/grid/perl/lib -I/oracle/app/oracle/product/11.2.0/grid/crs/install /oracle/app/oracle/product/11.2.0/grid/crs/install/roothas.pl

xynndp09:/oracle/app/oracle/product/11.2.0/grid/perl/bin/perl -I/oracle/app/oracle/product/11.2.0/grid/perl/lib -I/oracle/app/oracle/product/11.2.0/grid/crs/install /oracle/app/oracle/product/11.2.0/grid/crs/install/roothas.pl
Using configuration parameter file: /oracle/app/oracle/product/11.2.0/grid/crs/install/crsconfig_params
su: Illegal option -c
usage:   su  [-]  [username  [arguments]]
         su  [-]  -d  [username]
Run root.sh from a directory that has read/execute access to the grid owner 'oracle'



Solution:
The line in /etc/passwd file belonging to oracle user was like this:

oracle:*:300:300:Oracle Generic User,,,:/home/oracle:/usr/bin/sh

and changed to;

oracle:*:300:300:Oracle Generic User,,,:/home/oracle:/bin/ksh

then the problem solved.
