A Better Way to Take a XenApp Server Offline http://www.theshonkproject.com Wed, 08 Sep 2010 20:05:14 +0100 FeedCreator 1.7.2 http://www.theshonkproject.com/index.php?option=com_content&task=view&id=52#josc58 Hello, it is great to see new methods emerging to handle Presentation Server / XenApp. Unfortunately, there is a clear message about the state of CPSCOM. Vishal Ganeriwala has commented on my CDN page about CPSCOM [url]http://community.citrix.com/display/xa/First+Dive+into+CPSCOM[/url] that it is not supported by Citrix and that MFCOM is to be used instead. I have expressed my concerns [url]http://blogs.sepago.de/nicholas/2008/07/21/the-unavailability-of-cpscom/[/url] about officially publishing a CPSCOM-based script while not supporting the underlying API. Nevertheless, removing the server from the load balancing tables greatly helps on automated reboot schedules because no ONSTART tasks are necessary to get the server online. Regards, Nicholas Dille - [url]http://blogs.sepago.de/nicholas[/url].

Other than posting to CDN, you cannot get support or help for your scripts. Hey Joe, This is great. I like the idea of using the HMR, but haven\'t had enough time to get comfortable with it yet. As you pointed out I believe the two biggest advantages are by far... 1) A reboot will place the server back on to the LB table 2) Use HMR. Automatically have a server skip its scheduled reboot if too many servers are offline. I use an \"Out of service\" load evaluator instead, which I\'ve scripted here: http://www.jhouseconsulting.com/index.php/blog/2008/09/08/place-a-xenapp-server-in-and-out-of-service-the-easy-way/ My method makes it easy to take a whole lot of servers off line by using a PSEXEC script, and put them back on line again with enough intelligence so that it knows what load elaluator it was previously set to. If using your script, you first need to change the HMR settings to ensure it doesn\'t work against you. Would that be a fair statement? Cheers, Jeremy. Jeremy Saunders Sun, 05 Oct 2008 06:14:57 +0100 http://www.theshonkproject.com/index.php?option=com_content&task=view&id=52#josc65 Jeremy, in my opinion, MFCOM is fully supported by Citrix. The API is documented including all interfaces, enumerations and types. Citrix provide examples how to achieve typical tasks. I don\'t think Citrix can be expected to offer support for writing a script based on MFCOM other than reporting bugs in the API. I have had several dealing with Citrix Support concerning MFCOM-based scripts which stopped working after a new major release of Presentation Server / XenApp. I have been pointed to a new or updated interface to correct the script. If you are stuck with a script which should be working according to the documentation, just take it on with them ;-) In addition, some System Engineers are quite skilled in this area and are able to help you or forward your question to a colleague. Hope that helps, Nicholas.

Thank you, Tom Tom Mon, 12 Jan 2009 08:39:22 +0100 http://www.theshonkproject.com/index.php?option=com_content&task=view&id=52#josc196 The short answer is no. The HMR feature was added to 4.5 of which this depends on. This goes for the VB script and Powershell. Joe Joe Shonk Mon, 12 Jan 2009 10:34:26 +0100
