When Oracle 11gR2 11.2.0.2 RAC is installed on Linux today, the following error is reported.
By querying the log file content, the following prompt is displayed:
- INFO: 11rac2,11rac1
- INFO: PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "-x"
- INFO: Clock synchronization check using Network Time Protocol(NTP) failed
- INFO: PRVF-9652 : Cluster Time Synchronization Services check failed
It turned out that the NTP service was started and the-X parameter was not added. Add this parameter. Different parameter systems use different methods. The following is the LINUX method.
To the/etc/sysconfig/directory
- root@node01 sysconfig]# cat ntpd
- # Drop root to id ‘ntp:ntp’ by default. Requires kernel >= 2.2.18.
- OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"
Restart the ntp service.
Go to the RAC installation page and click "Re-check.
