Updates and displays the system time, NTP time server settings, and NTP server status.
SYNOPSIS
time { [ ‑list | ‑modify ] | ‑usage | ‑help }
DESCRIPTION
When using an external time source to provide the Oracle FS System with the current date and time, specify up to three external Network Time Protocol (NTP) servers by their IP addresses. The Oracle FS System uses port 123 to communicate with the NTP servers.
The Oracle FS System selects a server from a list of NTP servers to be the primary NTP server. After synchronizing with the primary server, the Oracle FS System periodically polls the primary server. If the discrepancy between the internal clock and time that is provided by any of the NTP servers is greater than 1000 seconds, the Oracle FS System stops attempting to synchronize.
Important! Default Windows environments use the Simple Network Time Protocol (SNTP) to synchronize Windows clients to one or more domain controllers. The Oracle FS System uses the standard NTP implementation for UNIX environments. Because SNTP and NTP are known to be incompatible, do not attempt to use a Windows system as an NTP server without a third party NTP service installed that is compatible with UNIX.
Important! In mixed environments, configure the NTP service on a UNIX system. Synchronize the domain controllers that the Windows clients are using to the defined NTP service. Then, synchronize the UNIX‑based clients to the NTP service. Do not synchronize the Oracle FS System or the UNIX clients to a Windows domain controller. When using NFS or CIFS file services, synchronize the Oracle FS System to the same time source that the clients are using to prevent loss of time synchronization.
Do not run the
time ‑modify ‑dateTime command to set the internal hardware clock as the time source unless the
Oracle FS System cannot reach any NTP servers or any file servers. If the management network becomes unavailable or access to the NTP service fails, disable the NTP service. Then, manually set the time. Run the following two commands separately.
time ‑modify ‑noNtpService
time ‑modify ‑dateTime date-and-time
Note: The GUI displays the time using the local time zone that is set on the GUI client. The CLI does not present any client-based information, including local times. All time information that is presented to you in the CLI is in Coordinated Universal Time (UTC).
SUBCOMMANDS
- ‑list
- Displays the current system time in UTC and provides information about the Network Time Protocol (NTP) servers if external time servers are being used. The status of each NTP server is displayed, including whether the server is being used by the Oracle FS System.
- ‑modify
- Configures the Oracle FS System to use the internal hardware clock or an external NTP service or configures the date and time on the Oracle FS System.
EXAMPLE
- Task
List the NTP servers configured and their detailed status.
- Parameters
-
