This article will explain in detail how to configure the fine-tuning mode of NTP on various platforms. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

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

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
