In this best practice, we implemented Network Time Protocol (NTP). The NTP synchronizes the clocks on the servers to ensure they are consistent across all databases.
Overview
NTP is used to synchronize clocks between computer systems using the network. By implementing NTP our Oracle database, the servers will be synchronized. Time synchronization is important for analyzing the systems, scheduling jobs, and 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.
Implementation steps
In Red Hat Enterprise Linux 8, the NTP protocol is implemented by the chrony daemon through the chrony package.
The steps to configure the daemon:
# yum install chrony -y
For example, adding NTP server 10.230.82.70 with this entry: “server 10.230.82.70 iburst”
# systemctl start chronyd
# systemctl stop chronyd
# systemctl enable chronyd
# chronyc tracking
# chronyc sources
# chronyc sourcestats
