Citrix Admin Do’h Moment – AMC 4.6.4

Last night, I upgraded a couple of our XenApp administration servers to the latest version of the Access Management Console (v. 4.6.4).  Ah, the AMC, we didn’t know how good we had it with the old CMC.  Anyway, I did the upgrade to address the slowness of using this console in our environment.  Discovery and doing most functions took a long time.

So, the upgrade went without issue and in the morning my co-workers remarked that the AMC is a lot more usable.  Of course, within an hour I found the same issue that several have written about in the Citrix forums like here and here.  Looking at a published application list on any of the servers resulted in stopping the IMA service on the server used for discovery.

There is a private hotfix available here.  You will have to have a valid MyCitrix login to get this hotfix.  I’m trying to get it now to see if it resolves the issue.

We also found the same issue with AMC 5.0.1 for Windows Server 2008.



XenApp Power and Capacity Management (Project Litoria) Technology

Out since late May of this year, Citrix XenApp Power and Capacity Management Technology is currently available as a tech preview here.  iForum 2009 in Melbourne just finished and they demonstrated this technology in the closing keynote.  The use of this technology can really make a difference in your bottom line in terms of power and cooling savings.  It is a rethinking of XenApp’s mature load balancing technology and is another way of looking at server utilization (which was much of the argument for moving towards server virtualization a few years ago).   This product, combined with Provisioning Server, is perfect for the environment I manage.  Our farm is over-built in anticipation of an event that would force most employees to telework, so our servers are typically underutilized.  Check out the video below.


Creating a Green Dashboard – Part 2

In the first part of this series, we covered gathering data on external users and how to parse that data into a database.  To generate the data to show how your Citrix farm positively impacts the environment and quality of life for your teleworkers, you need to get the average statistics for them.  Governments gather this data as it pertains to their own telework programs.

The U.S. government site,, provides a one-stop-shop for general information, but no hard data except for number of participants at the various agencies.  We need a site that will give us savings on money, fuel, and pollutants. 

The Telework Exchange has a lot of papers and studies, and it provides statisics for yourself, based on location and miles driven.

The most detailed information I’ve been able to find so far, is the Undress4Success site.  This site has quite of bit of information as well as links to job boards and details of “work at home” scams.  They also have done a lot of the work of analyzing many telework studies and making it available to visitors.

For this example dashboard, I’ll track gas saved and green house gas savings.

For gas saved in my geographic area, this is 2,847,724 gallons saved per year or approximately 177 gallons per teleworker (16,058) or roughly 0.50 gallons saved per person/per day teleworking.

Following the same method for greenhouse gases, 26,991 metric tons are saved annually.  Using Google to convert this to pounds, gives us 59,504,969 pounds saved.  This breaks down to 10 pounds saved per person/per day teleworking.

Using these amounts to start with we can show the amount of gas and greenhouse gas emissions someone is saving per day when they use our Citrix farm.   This is just a starting point, we could expand this to other cost savings for the teleworker and for the company as well which I’ll cover at the end of this series.

A hard, rough, abrasive look at camel spotting…no dromedaries…no virtualization.
