When trying to Run the Runcluvfy command to check RAC pre requsiites the NTP failed , but at the same time it’s gives you the solution to solve it :-
in the following file :- /etc/sysconfig/ntpd open it and edit it, add the following :-
[root@prddb2 .ssh]# cat /etc/sysconfig/ntpd
# Drop root to id ‘ntp:ntp’ by default.
OPTIONS=”-x -u ntp:ntp -p /var/run/ntpd.pid -g”
Add the above letter in RED color only.
Thanks
