Is there a way to verify if I have already been patched?

Thanks for the heads up.


How come every time DST comes around there seems to be another bug/patch that needs to be done? It seems ever since the first DST changes 2-3 years ago and patches, we need to keep doing other sets of patches for other DST bugs.

I have to agree on this. Thanks for the heads up on the patch, but come on. Year after year we deal with this. It's not a bug anymore, it's lazy programming.

We installed the patches back in March when this issue occurred. Are these the same patches or do I also need to install the ones you have listed here?

Hi Efrain,


The "Patches" from March will not fix the November DST changeover. You will need to upgrade/patch your boxes with the applicable version :(



This is the March Patch info;


Workaround #3:

Apply a patch from Cisco.com. This patch works on all Versions of CUCM 5.x-7.x


Software Download Center path:

Voice and Unified Communications > Cisco Unified Communications Manager

Version 7.0 > Unified Communications Manager/CallManager Utilities > UCM COP

Files


The same patch file is used for all versions of CUCM Versions 5.x-7.x


Do not install this patch on subscriber server. It is for publisher only.


A new patch has been released. The original patch documentation advised to only install on publisher. However, some users attempted patch subscribers and an extermely few of those experienced catastrophic failure. That failure is captured in CSCsy33380.


The original patch and corresponding md5hash were:

ciscocm.dst_march_2009.cop.sgn d4f5e2562982f9fdaf4446be2ae08df1


The new patch and corresponding md5hash are:

ciscocm.dst1_march_2009.cop.sgn d60c522e294a3ca9e7cceaeda51dc181



A Field Notice is posted on this issue here:

http://www.cisco.com/en/US/customer/ts/fn/632/fn63213.html


Please follow the steps listed in the Field Notice to follow up if you have questions.




Further Information:

The workaround is only a patch to correct time issues for the week of

March 8 - March 15, 2009 for US

March 15 - March 22, 2009 for Argentina


Any timezone which changes on Friday or Saturday is actually addressed by CSCsy33379.



***Here is the reference to this requirement;



After that time will be correct until DST ends in November. ***Additional permanent fixes will be released later this year to correct DST fallback in November and to remove changes for this specific patch so that DST will begin and end correctly correctly in 2010.


Hope this helps!

Rob

When I look at my Publisher it says I have this file installed. ciscocm.dst_march_2009.cop


I'm assuming I'm good to go. I followed the link above and got to a pdf that said the cop file is no longer availab.e.

Hi Efrain,


Let's try this again :) I'm sorry for all the extra info in the earlier post.

I sure thought I had this fixed last year, but apparently not. This morning, November 2nd, I have to keep our publisher set as Mountain Time even though I'm in Central Time. So, something still isn't patched right.


If I'm reading this right, the patch listed above is only for March and only for Argentina Time... I'm scrambling to find the patch I need for CUCM 6.1.3 -- Like I said I thought I did this last year but even so, it's not resolved. Is there a patch available that fixes both the March and November issues for 6.x or is something we need to fight with every year?

Hi Scott,


What a pain in the ...


There is no patch for this anymore, the solution is to upgrade to a version of CUCM that includes the permanent (hopefully) fix :)


For you, these would be the versions;


6.1.3.3000.1 , 6.1.3.2190.5, 6.1.3.2104.1 or 6.1.3.3190.1



Hope this helps!

Rob
