This article guides you through the steps required to configure the automatic time synchronization via NTP servers on EXASolution clusters.
If the time shift is greater than one hour it is required to set the time at first manually, which is described in Manually setting time via EXAoperation. There is no downtime need if the time shift is less than one hour.
⚠️ Please note that:
The cluster nodes constantly exchange configuration and vitality information and depend on proper time synchronization. While it is possible to manually set the time on EXASolution clusters, it is highly recommended to supply NTP servers for time synchronization.
The tasks performed in EXAoperation requires a user with at least "Administrator" privileges.
Please ensure that the NTP servers provided to EXAoperation
are connectible from the cluster (port filtering, firewalling) and
can be addressed by name or IP address (i.e.: hostnames must be resolvable through DNS). Check the gap between the currently configured time and the actual time
