Basic Administration for Citrix XenApp 6 – Additional content

Two weeks ago I had the pleasure of delivering the first XenApp 6 class in Denmark. Even though we experienced some technical issues in the labs, due to the extremely high hardware requirements for the lab computers (A problem that was solved late in the evening on day two), it was a great experience. I had the pleasure of teaching a great team of students and I think we all had a good time learning what’s new in XenApp 6.

I promised one of the student to post links to some of the information, that I mentioned as part of the class. Some of this content I used as part of my preparation for the class and some was actually shown as part of the class.

Whiteboard introduction to the Citrix HDX technologies by Michael Harris:

I love the simplicity by which Michael Harris introduces the HDX technologies. I normally use this short presentation as part of my classes, either by playing the video, or by doing it myself at the whiteboard. I actually meet Michael in San Francisco, at Synergy, but forgot thank him for the great presentation.

XenApp 6 to be released Marts 24th

Last week Citrix announced the release of XenApp 6 on Marts 24th. With less than 10 days to go I want to summarize some of the great new features in the upcoming release.

The last months I have had the opportunity to play around with the tech preview of XenApp 6 in my lab. I’m surprised how many great new features will be added in XenApp 6. Now we just ned to see the stability and scaling in real-life.

First of all XenApp 6 will support Windows Server 2008 R2. Citrix has rewritten the code-base to fully support Windows Server 2008 R2 x64 architecture.

I have made a list highlighting most of the new features:

    • New Citrix Receiver for Windows, Mac and Linux.
    • Single auto-updating client using plug-ins.

    • Group Policy templates and integration. Rapid server, application and user access configuration.

XenApp tuning document re-born

For what seems to be a life-time ago, Rick Dehlinger was the editor on the ”Citrix MetaFrame for Windows Servers – Installation and Tuning Tips” guide.

This great pdf-document featured tips and tricks for the Citrix administrator. I remember both me and my colleges, had great use of the document and every release was closely examined.

I don’t recall when Rick published the last version, but a quick search in my old documents returned the version from April 2000.

I had a quick look at it and to my surprise there’s still a lot of great tips in the guide.

For the fun of it I have included the document here.

Now the project has been reopened and will be updated on a voluntary basis through the Danish Citrix User Group. The editor of this new edition is Christian Fenneberg from Arrow ECS in Denmark, a long time friend and college of mine. The first release of the document is a ”beta” release, this release is lacking some sections, but there is still a lot of useful information. If we all help, this document have the potential to get as good as its predecessor.

Even though it’s a Danish initiative, the document is in english, for all the world to enjoy. I know for a fact that everybody welcome to participate.

You can download the new document from the Danish Citrix User Group’s site.
