How to configure the fine tuning mode of NTP on each platform

Editor to share with you how to configure NTP fine-tuning mode on various platforms. I hope you will get something after reading this article. Let's discuss it together.

For versions prior to 11.2, the restart of many environments (in the case of top5) is caused by the excessive pace of NTP adjustment time, so we recommend that users in RAC environments need to be configured in fine-tuning mode if they use NTP

For the specific reasons for the restart, please refer to Allen Gao's blog: how to diagnose node restart problems.

Here are several configuration methods of NTP fine-tuning on mainstream linux and unix platforms:

For Linux:

1. Please make sure that the ntp package for each node has been installed. I have a version 4.2.2 here.

[oracle@nascds10 ~] $rpm-qa | grep ntp

Ntp-4.2.2p1-9.el5_4.1

two。 Please edit the ntp.conf file of each node

[oracle@nascds10 ~] $su-root

Password:

[root@nascds10 ~] # vi / etc/ntp.conf

# New ntp server added by Robinson
