Solaris

Hello all,

I just want to update the timezone file with new file to update the time, so the zone in /etc/TIMEZONE will be the same but the file it refers to will be changed, and the local time should be changed, can this take effect without rebooting Solaris 10?

Timezone is the representation of the system time.
If you change the timezone, applications might continue with the old representation, until they are restartet.

It is both unclear what file you plan to change and what need to be changed in it.

Can you provide more details about what is precisely expected?

Thanks for your Reply

/etc/TIMEZONE contains a timezone for example TZ=Africa/Tripoli as i know in solaris 10 to change this timezone i must restart the server so I will leave it as is and replace Tripoli file itself that contains new time (GMT+2 instead of GMT+3) so how to make this file take effect on the system without restarting the server?

No matter what files you change, the TZ setting of already running processes will not be affected. If you want to change the TZ setting in an application that is running, you need to restart that application.

If I understand properly, you do not want to change the timezone which will remain TZ=Africa/Tripoli but you want to replace the file storing the timezone definition, here /usr/share/lib/zoneinfo/Africa/Tripoli, by a file containing a different definition, presumably built with the zic command.

Assuming this is what you want to do, changes should affect the existing and future processes time representation immediately, i.e. without requiring a reboot. However, this is unsupported and there is a risk for a Solaris patch to overwrite your customized timezone.

Of course any new processes after the update will pick up the new timezone and that could mess up any logs that you write.
