CCM updates for timezone change?

Are there going to be any Cisco OS or CCM updates for the DST timezone changes coming up , or do people just follow the methods in the MS knowledge article?

Re: CCM updates for timezone change?

Good catch. Hopefully MS comes with an update that automatically does this.

Re: CCM updates for timezone change?

On the Call Manager Side we have 2 defects opened for this issue. They are as follows ...

CSCsf07541 - MCS-OS Update needed for N America DST changes in 2007

CSCsf07523 - Update needed for N America DST changes in 2007

You can view these defects at the following link below ...

http://www.cisco.com/cgi-bin/Support/Bugtool/home.pl

In short we are going to be covered with CallManager versions 3.3(5)ES56 4.1(3)ES89.1 4.2(1)ES38 4.2(3)ES11.1

All the other versions of CallManager will not have this bug fix.

Re: CCM updates for timezone change?

Is the CCM update needed? If you just do OS update and not CCM will be there be any problems in US? Other than maybe date/time groups being off maybe.

How about 4.0(2)? Will those customers have to go 4.1(3) or 4.2 to get the update? Why not a SR and a ES?

Thanks

Re: CCM updates for timezone change?

win-OS-Upgrade-K9.2000-4-3a-sr8 has the fix from an OS perspective. You can check avability at the following link

http://www.cisco.com/cgi-bin/tablebuild.pl/cmva-3des

On the readme notes you can see that.

Re: CCM updates for timezone change?

I thought we only need to run the tzedit.exe tool from MS to adjust the DST on the Windows OS and that should take care of everything since CallManager is getting its time from the Windows OS. Is this true ?

Re: CCM updates for timezone change?

Noooo!!! that is only for Unity, you can not use any tool that is not on CCO for CallManager. For CCM you need to upgrade both the OS and the CCM version to be fully patched for the DST changes.

Re: CCM updates for timezone change?

Thanks for the info. Do you happen to know if anything needs to done with IPCC Express or CER servers for this update?

Re: CCM updates for timezone change?

Jorge,

does this mean, OS update 2000.4.4 (+/- SR2) has this fix already ?

Re: CCM updates for timezone change?

Sankar, I haven't reviewed that OS, but you can check the Readme notes for that OS, it has all the bugs that are fixed the OS.

Re: CCM updates for timezone change?

I just checked that, the fix for CSCsf07541 was included in 2000.4.4sr2 and later.

Re: CCM updates for timezone change?

Hi all,

This is very important to everyone here, please correct me, I got a little confuse here.

Let me conclude what we know:

FOR CCM:

You need 2000.4.4sr2 and later for new daytime saving setting.

FOR Unity (messaging only):

Need tzedit.exe tool from MS.

For Unified:

As long as Domain Controller patch, unifed server should get the right daytime saving from Domain, RIGHT???

Thanks a lot!!!

Ken

Re: CCM updates for timezone change?

For CCM you need:

2000-4-3a-sr8 or later (for this train) or 2000.4.4sr2 and later (for this train) and any of the following ES's: 3.3(5)ES56 4.1(3)ES89.1 4.2(1)ES38 4.2(3)ES11.1

For Unity:

At this moment only the tzedit.exe tool from MS, not sure if the developers will make a patch for Untiy, we haven't been informed on that matter, you can post that question on the Unified Communicatios forum and ask Jeff Lindborg.

Re: CCM updates for timezone change?

What about customers who are running 4.0.2a ? What is the workaround for this release ?

Thanks !

Danny

Re: CCM updates for timezone change?

No workaround, you will have to change the time manually.

Re: CCM updates for timezone change?

Well, with 4.0(2a) they could update to 4.1(3) or 4.2(3).

Is there an issue that will be noticed on systems that are not updated other then the time not changing/adjusting on it's own correctly?

Would call manager date/time features be effected without the CCM updates? IE: How crucial is it for the CCM updates if they are on earlier versions?

Re: CCM updates for timezone change?

If you are using a NTP server for CCM and IPCC, do you still need the patches. I am assuming yes in the event you lose connectivity to the NTP server.

Re: CCM updates for timezone change?

I also found out that for IPCC Express/CRS, there's going to be a notice from cisco going out in a week or so with details.

In short, TAC had told me that IPCC Express/CRS 3.5(4)SR2 will have fix, and anything lower will need to be upgraded. The 3.5(4) SR2 will have a JRE update also for the DST changes.

IPCC 4.0(1), 4.0(2), 4.0(3), 4.0(4), 4.5(1), 4.5(2) will need the OS update and Sun JRE DST patch.

Re: CCM updates for timezone change?

NTP hands out UTC only, the OS performs the DST offset calculations from it's own data.

New Member

Re: CCM updates for timezone change?

Can someone explain how Cisco decided to bypass the fix for 4.0.2a.

New Member

Re: CCM updates for timezone change?

What about other Unified servers? IPCC Express? Meetingplace Express? Ops Manager?

Cisco Just released this...I'm using this currently as a map for 2007 Energy Policy Act

Re: CCM updates for timezone change?

For all CCM and IPCCX, there is ntp server loaded automatically after Cisco application is installed. The time sync path is, IPCC get sync'ed from CCM, CCM Subsriber gets sunc'ed from publisher, and publisher sync with its' local time.

So for the DST, all servers have to be updated with new DST dates, either tzedit.exe or Windows patches shall work.

Re: CCM updates for timezone change?

With this document (http://www.cisco.com/en/US/customer/tech/tk648/tk362/technologies_tech_note09186a00807ca437.shtml) it is apparent that those customers running 4.0(2a) don't have a solution to this issue.

I'd like to understand why it is necessary to have a CallManager patch in the first place. Why would the OS patch (CSCsf07541) be tied to a version of CallManager? What are the dependencies with respect to DST/Timezones and when they begin and end for CallManager and Windows. Why is 4.0(x) not included?

Any guidance will be appreciated.

Thank you.

Re: CCM updates for timezone change?

A new single patch for the Daylight savings was released the day before yesterday, you can find it on CCO:
