Citrix XenApp or XenDesktop: A decision tree

Citrix offers two products to deliver hosted resources to users: XenApp and XenDesktop. Although the products share great similarities (and since v7.x the underlying architecture is now common, FMA rather than IMA),  have their unique characteristics.

What product do you need? When and why? In this article I’m trying  to help you make this decision based on a decision tree.

During the course of this article I’m assuming you’re designing a XenApp / XenDesktop 7.x environment, however the principal is equal for XenApp 6.x and XenDesktop 5.x.

Citrix released “XenBroker 7.5”

Rest In Peace - Citrix XenAppIn 2013 Citrix merged their application and desktop delivery solutions XenApp and XenDesktop into XenDesktop 7. XenDesktop 7 (XD7) combined the ability to provide remote access to single- and multi-user Windows platforms improving their FlexCast technology.

Besides that we got rid of the ancient IMA architecture, what I liked most was the fact that there’s  now one single product to offer access to single- and multi-users applications AND desktops: XenDesktop. Nonetheless we had to let our beloved XenApp go. After numerous evolutions and name changes (WinFrame >> MetaFrame  >> Presentation Server >> XenApp) this was the end of an era. But, Citrix did skip the cursed version 6 for the XenDesktop product range. Hooray!

Citrix Receiver: You have not chosen to trust “COMODO High-Assurance Secure Server CA”, the issuer of the server’s certificate

Citrix ReceiverRecently I started using a MacBook to replace my Windows laptop. Since I work as a technical consultant with Citrix products I frequently connect to a Citrix XenApp / XenDesktop environment, amongst other to our lab.

While the installation was straightforward (just go to receiver.citrix.com and click on Download Reveiver for Mac) I quickly faced a dialog telling me I haven’t chosen to trust the CA certificate with no option to solve this…

Microsoft App-V: Dynamic Configurations or RES Workspace Manager?

Written by Ingmar Verheij on January 22nd, 2014. Posted in Microsoft App-V, Workpace Manager

When you’re using Microsoft App-V 5 to distribute your “virtual” applications it can be cumbersome to apply settings afterwards. With native installed applications you have to ability to update files, registry settings or apply permissions (since App-V 5 always applies default permissions).

Within a virtual application these settings needs to be applied within the virtual environment (often referred to as “the bubble”). Up to App-V 4.x you had the ability to add custom actions in the OSD file, starting App-V 5 this is replaced with Dynamic Configurations.

While Dynamic Configurations are more powerful and flexible then the static OSD files I couldn’t resist to show you how RES Workspace Manager can simplify this.

Citrix NetScaler: Cannot load applet (7u51)

Java Update AvailableOn January 14 Oracle released Java Runtime Environment (JRE) 7 update 51. Just like previous updates the raised the security level which could potentially break existing applications. We saw the same when they released 7u45, back then I found a more constructive (but complex) solution to solve a problem where the GUI hanged at “Downloading Applet..

Citrix updated their NetScaler software to meet the requirements of Oracle on December 3rd (download, release notes) – I hope that back then you reverted to a more secure JRE. Unfortunately JRE 7u51 gave me again problems, this time the Java Applet could not be loaded.
