ntpd[]: frequency error PPM exceeds tolerance

edited Oct 21, 2019 6:04AM in Database - RAC/Scalability (MOSC) 3 commentsAnswered ✓

Yesterday we had to reboot one node of our 3node RAC-Cluster. After reboot and startup of all instances we noticed the following message in /var/log/messages :

ntpd[]: frequency error PPM exceeds tolerance

When checking the date we noticed that the time was 4/5 min behind when comparing with the other 2 nodes.

Question : Can we run the following :

# service ntpd stop

# service ntpdate start

# service ntpd start

on a running rac-cluster to sync the time ?

Howdy, Stranger!
