In this best practice, we implemented Network Time Protocol (NTP). The NTP protocol synchronizes the clocks on the servers so the time is consistent across all the databases.

Overview
NTP is used to synchronize clocks between computer systems using the network. In implementing NTP our Oracle database servers will be synchronized which is important for analyzing the systems, scheduling jobs, and perhaps implementing Oracle Real Application Clusters. This is a configuration best practice as the goal is to have all our database servers synchronized from the same NTP server.
Recommendation
We did not expect a significant impact to performance in implementing NTP on our servers. The following performance metrics did not change when NTP was running on the database servers:
Implementation Steps
In Red Hat 8, the NTP protocol is implemented by the chrony damon through the chrony package
