DAYLIGHT SAVINGS TIME PATCH QUESTION

[rmueller58]

I found the PHCO_24673 Patch for the upcoming daylight saving time change.

Can someone provide me with the "swinstall command to avoid an auto-reboot? would it be

swinstall -x autoreboot=false -x patch_match_target=true -s /tmp/PHCO_34673.depot

Where the readme shows:
swinstall -x autoreboot=true -x patch_match_target=true \
-s /tmp/PHCO_34673.depot

any insight appreciated. We reboot nightly I'd prefer to install this and wait for rebooting the system.

Hi Rex:

*NO* reboot will occur during the patch's installation.

The '-x autoreboot=true' simply tells 'swinstall' that its acceptable to reboot if any patch requires it.

You can install the patch in question using the syntax shown and reboot at *your* convenience.

Regards!

James or anyone, are you aware whether the DST patch forces a reboot?

[James R. Ferguson]

Hi Rex:

No, the patch does not force you to reboot. However, it is advisable to do so sometime before the Daylight Saving transition.

This allows all long-running processes to re-read/re-cache the updated '/usr/lib/tzlib' configuration.

You should at least restart 'cron' and any databases if you don't elect to reboot.

Regards!

As James already said, NO, the DST patch does not force a reboot.

You can also verify this in the patch text file. There is a section "Automatic Reboot" and it will say Yes or No.

In this case:

Automatic Reboot?: No

thanks guys.. I am little out of it.

The patch does NOT require a reboot.

However it would be a good idea to have a scheduled reboot after the patch install in order to insure all your apps have read the correct time.

Also, Java requires either an upgrade or an update (in the form of the tzupdater applet.

We reboot nightly, I want to apply the patch before I head home at 5:00 our reboot happens at 11:30 PM.

We have an Informix sysdate updater that runs after reboot.

>We reboot nightly

Do we dare ask why?

[rmueller58]

Dennis,

we reboot nightly to kill informix connections before running exports, it was the only thing that seemed to kill the open procs.

Thanks all, Sorry for the late closing
