This alarm indicates the server's current time
precedes the timestamp of the last known time the servers time was good.
Severity:
Critical

Alarm ID:
TKSPLATCR17
Cause:
The server's current time precedes the timestamp of the last
known time when the servers time was good.
Diagnostic Information:
N/A.
Recovery:
Verify NTP settings and NTP sources are providing
accurate time.
Ensure ntpd service is running with correct
options: -x -g
Verify the content of the /etc/ntp.conf file is
correct for the server.
Type
/usr/sbin/ntpdc -c sysinfo to check the
current state of the ntpd daemon.
Verify the ntp peer configuration; execute
ntpq -p; and analyze the output. Verify peer
data, such as tally code (first column before remote), remote, refid, stratum
(st), and jitter, are valid for server.
Execute ntpstat to determine the ntp time
synchronization status. If not synchronized or the stratum is not correct for
server, then ping the ntp peer to determine if peer can be reached.
If ntp peer is reachable, then restart the ntpd
service.
If problem persists, then a reset of the NTP date
may resolve the issue.
Note:
Before resetting the ntp date, the applications
may need to be stopped; and subsequent to the ntp reset, the application
restarted.
Reset ntpd:
sudo service ntpd stop
sudo ntpdate <ntp server
IP>
sudo service ntpd start
Confirm recommended NTP topology and strategy.
No fewer than tree references are recommended.
If selecting a different number, the number
should be odd.
No intermediate reference should be a
virtualized server.
Additional recommendations and topology are
available in the NTP strategy section in the
DSR Hardware and Software Installation 1/2 customer
document.
If the problem persists, it is recommended to
contact
My Oracle Support.
