Explanation:
Because Oracle Clusterware works closely with the operating system, system administrator
access is required for some of the installation tasks. In addition, some of the Oracle Clusterware
processes must run as the system administrator, which is generally the root user on Linux and
UNIX systems and the LocalSystem account on Windows systems.
