Hi

How often the time is changing?
Did you set NTP?
Did you set time zone?

[Shehan]

We saw this yesterday. At that time, we saw only one hour difference. But it 11 hour difference.

In addition to that we didn't do any changes in the server.

Anyway,While this is examined, can we know whether we can change the current time in to correct time while oracle is running.

It seems that you have a problem with the ntp server that's giving out the time.

Another problem, could be change of timezone. Make sure that you are using the correct timezone and reconfigure it all to make sure.

# vi /etc/TIMEZONE
TZ=MET-1METDST
export TZ

# vi /etc/ntp.conf
server your.timeserver.com version 3 prefer

# vi /etc/rc.config.d/netdaemons
export XNTPD=1

Can we do this in a live system? or else do we need to take it into single user mode.

no, you need not go to single user mode to change the Time zone. biut you need reboot to change effect.

[Dennis Handly]

Do you have the right TZ settings?
What does this show:
date; date -u

[Dave Johnson_1]

Did you apply the TZ patch when the dates for start/end of daylight savings time in the US changed last year?

set_parms timezone

Select a timezone based on your country of location.Also allows you to set a user-supplied timezone.
The system must be rebooted for any change to take effect.

set_parms date_time

Set the system date and time interactively: This is similar to calling date as a privileged user but without having to format a time specification. The change takes effect immediately.

Hi All

I am in GMT+6 time zone. How do I change server time into GMT+6. Also once we set GMT+6 , what does it give from "date -u " command

>I am in GMT+6 time zone. How do I change server time into GMT+6. Also once we set GMT+6 , what does it give from "date -u " command


your /etc/TIMEZONE should show the following:
SRV2:etc>cat TIMEZONE
TZ=GMT-6
export TZ


And when you run the "date" and "date -u" the following should be displayed:
SRV2:etc>date
Fri May 2 08:14:15 MRU 2008
SRV2:etc>date -u
Fri May 2 02:14:18 UTC 2008
SRV2:etc>


hope this helps!

hi again Nirukshitha,

is this is production system, you may wish to shutdown your databases and applications before making the changes.

when you finish making the changes, a reboot would ensure that everything has been properly setup.

good luck!
