I’m verry happy to announce that since the 10.1 build 122.11 all is fine again and there is no need to change Java settings. If you are not able to upgrade right now please continue reading.
Normally I’m not all that in to short articles about fixing bugs but this one is nagging so many people I couldn’t resist in jumping in.
Some time ago I started running into issues with the Citrix NetScaler Java applets build in to the GUI. I ignored it for a while because I’d always had my own laptop with me that worked every single time . So here I was thinking I was so smart because I had the only working system in the world……. But then one day it just stopped working, it would load the applet up to 1% and then froze.
After countless hours of troubleshooting I finally gave up and went to Google to notice I of course wasn’t the only one having problems. The fact is that none of the threads on the Citrix support forums ended up in a completely working solution until I started combining them.
So here’s the fix!
Open up the Windows Control Panel and start the Java Control panel.
Now go to General -> Temporary Internet Files -> Settings and Unselect Keep temporary files on my computer.
Now go to General -> Advanced and configure the following options
“Mixed code (sandboxed vs trusted) security verification” = “Disable verification”
“Perform certificate revocation checks on” = “Do not check”
I hope this was of help! Please use the comments sections for your questions.
With the release of Citrix XenDesktop 7 two provsioning methods are now available which fully support hosted shared (HDC) and hosted private (HDC). The first provisioning method is Citrix Provisioning Services (PVS) and the second is Machine Creation Services (MCS).
There are a couple of important differences between the two provisioning methods which you need to know before choosing the right method for your design. In one of my earlier articles I showed a decision tree which helps choosing between both methods. I would recommend to read this great article about storage resource usage, by Nick Rantalan, as well.
This article focusses on a very important difference between Citrix Provisioning Services and Machine Creation Services, Advanced Image Management.
Advanced Image Management
Advanced Image Management (AIM) is more than simply assigning an image to a specific machine or a group of machines. It’s about a proper way of upgrading and assigning images according to DTP principles in a simple and time efficient manner. Automation plays an important part of AIM as it saves time and more importantly leaves out the possibility of human errors. Andrew Morgan wrote an excellent article about why you want to prevent human errors by using automation.
PVS offers great image versioning functionality, automated DTP and even automated image updates with the integration of third party solutions like Microsoft System Center Configuration Manager. This Citrix article explains the functionality in fine detail.
Citrix XenDesktop 7 VDA
This will be a short article about an issue I ran into automating the Citrix XenDesktop 7 VDA installation.
As described on the Citrix edocs a silent install of the XenDesktop 7 VDA should be really straightforward. This is exactly what I was seeing when installing the VDA on Microsoft Windows 7, Windows 8 and Windows Server 2012.
Citrix XenDesktop 7 is probably one of the biggest product releases by Citrix ever. The consolidation of two of the strongest products, XenApp and XenDesktop into one single product is a huge step forward on so many levels!
For those of you who worked with me or who I had the honor to discuss IT in general, know that I focus on simplicity. I can get really irritated about products with great functionality but are managed with terrible management tools and a lot of different consoles. This is why I love products like SMS Passcode and RES Software products.
For what I’ve seen in the latest announcements and while testing preview releases of XenDesktop 7 (also known as Excalibur), this really is a product that comes close to true simplicity. I’m really happy with the consolidation of products, features and consoles.
This article is not going to be a “what’s new and hip style” article, there are plenty of those out there. What I want to show you is how much simpler this release makes our lives on a product and architectural level. Not only on the implementation side but especially on the management side.
NetScaler Sizing Guide intro
About a year ago Citrix started with the NetScaler Tri-Scale method to scale up, in or out the Citrix NetScaler platform. Although this sounds great and gives you an option to pay-as-you-grow we all understand that we should take proper care for initial sizing. Doing so makes sure your users won’t be disappointed and plain simply pay less $$$.
Citrix NetScaler Access Gateway MPX
My focus for this article is small to midrange sized Citrix NetScaler platforms up to the MPX 8600 6 Mbit/s. My experience is based on projects within the Netherlands and unfortunately for me this is as big as it gets. This doesn’t mean you can’t use the information when sizing larger platforms. This is also the reason why you will not find any information about clustering in this article.
This article is a follow up on two earlier articles mainly focused on the performance and sizing of a virtual (VPX) Citrix NetScaler
Access Gateway, now called NetScaler Gateway.
How to maximize your virtual Citrix NetScaler Access Gateway performance
Citrix NetScaler Access Gateway VPX user scalability numbers explained
This leads to questions about why there is a difference in theoretical and practical numbers. I’m not Google and therefore can’t answer them all but I will try to answer some of them.
In the Enterprise Mobility Management playing field Citrix is betting big on Citrix XenMobile with new products, new editions and great integration. It’s clear that the EMM playing field is growing rapidly and according to Gartner it’s already on the nr 1 and 2 position of Strategic Technology trends for this year.
To understand the true value of the Citrix XenMobile Enterprise Mobility Management suite it’s important to know the definitions for the different kinds of Enterprise mobile solutions.
