CCM 4.0(2) and Unity DST Changes

marcuscastellanos · ‎03-05-2007

I'm preparing for the DST Changes this sunday. I am on CCM 4.0(2) and Unity 4.0(4). I read through the forums and found this post: "it is apparent that those customers running 4.0(2a) don't have a solution to this issue."

After doing a little digging around, Unity appears to have a fix from:

CCM 4.0(2) If I am reading correctly from:

http://www.cisco.com/en/US/customer/products/sw/voicesw/ps556/products_field_notice09186a00807e02b1.shtml

I should be able to apply the following patch:

CM Appliance OS - 4.1(3)

Includes SR's 4.1(3)SR4d and below

SR's 4.1(3) and below should work for 4.0(2) no?

Appreciate any help anyone can give.

Thanks

Hi Marcus,

You would have to upgrade CCM to 4.1.(3) to be able to use the DST Patch you are referring to. This is why there are people so unhappy with Cisco for not working up a patch for CCM 4.0.(2) There are only patches available for the latest release in each train (3.3(5), 4.1.(3) and 4.2.(1)) :(

Given that fact,

There is also a manual workaround just in case you are running out of time;

CCM OS Manual Workaround 3.x and 4.x

On the new US DST date, Logon with sufficient privileges to CCM Windows Server (starting with Publisher)

Click Start, Settings, Control Panel, Date and Time

Adjust the time accordingly

Click on TimeZone tab

Uncheck the Automatically adjust clock for daylight savings changes

Click Apply or Ok

Repeat steps for all servers in the cluster.

When DST ends in the Fall, the clock would have to be manually adjusted again using the same method described in steps 1-3 and 6-7 above. Please note, however, that manually adjusting the clock on CCM servers could result in a conflict in time which may produce time synchronization issues.

From this doc;

Hope this helps! Sorry to bum you out with this news,
