Oracle Linux: How to Start NTP Service With Slewing Enabled
(Doc ID 2422934.1)
Last updated on AUGUST 04, 2018
Applies to:Linux OS - Version Oracle Linux 5.0 and later
The goal of this document is to set NTP slewing option on NTP clients so that the service starts with slewing enabled.
The NTP daemon will periodically update the system clock with the time from a reference clock. If the time on the reference clock is behind the time on the system clock, the system clock will be set backwards in one large decrement. Such swift changes in time can lead to Oracle shutting down the node due to inconsistent timers. To avoid this problem, NTP can be configured to slew the clock. When slewing the clock the time on system is incremented slower until the system clock is in sync with the time on the reference system.
