This issue appear on my Presentation Server 4 HR5, 32bit only, x64 servers (Windows 2003 & 2008) were fine after deploying Citrix Edgesight Agent for XenApp 5.2 SP1. (build 5.2.3012.0) Impacted applications : All java applications using more than 706mb of reserved memory, command line example :  c:\Progra~1\Java\jre1.5.0_07\bin\javaw -Xms8m -Xmx1024m -Dcai.starter.jvm.options="-Xms8m -Xmx1024m" -classpath d:\xxxxxxxxxxxxx Visual Studio 2008 Pro SP1 x64 crashes when Citrix Edgesight 5.2SP1 is installed, process CL.exe. Reminder : -Xmsn Specify the initial size, in bytes, of the memory allocation pool. This value must be a multiple of 1024 greater than 1MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 2MB.       -Xmxn Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB.  Affected system : Microsoft Windows 2003 R2 Sp2 x32 with Citrix Presentation Server 4 HR5 Error message : Or Even if the Presentation Server all have 4Gb of ram,  and freshly rebooted (567mb memory occupation) the java application doesn't want to start. I first uninstall Citrix Edgesight, and checked everything was fine, it was fine with prior Edgesight for XenApp's version. Someone had the same issue, only one person posted this issue with a java application on Citrix's forums : http://forums.citrix.com/thread.jspa?threadID=261266&tstart=0  About the Visual Studio 2008 SP1 x64 the process CL.exe seems the one to exclude to make it work. Workaround : To avoid EdgeSight for XenApp agent "blocking" a process, you need to hade the executable program to the following registry key : You need to keep in mind, adding file to this registry key excluding them from statistics (information to confirm) Update 30 march 2010 : There is no fix yet for this issue, Edgesight for XenApp 5.3 next version should include the fix, but not before Q2 2010...

With this new version, Citrix give support to XenApp 6 and Microsoft Windows 2008 R2. Beware, the new Edgesight XenApp Client 5.3 is only made for Windows 2008 R2 and XenApp 6. For prior OS and XenApp version you must use the 5.2.1 version. There are a bunch of new reports available now, since Resource Manager is dead, Citrix needs to implement everything what we were use to find in RM. This is a small step but nothing big except for the licensing part, a brand new section is dedicated for licenses reporting. What's new ? Monitoring of Citrix License Servers and reporting on license usage by product group or individual products. The license servers to be monitored are specified at Configure > License Monitor Configuration > License Servers. License usage reports are available on the Track Usage tab. Monitoring of Published Applications and reporting on application launches and unique users. Published application reports are available on the Track Usage tab and the Browse tab. Monitoring of session duration by farm or user group. Session duration reports are available on the Track Usage tab and the Browse tab. EdgeSight Agent support for XenApp 6 Warning : if you have a SQL 2000 database, you need to upgrade to SQL 2005 or SQL 2008 ! So here are some screen shot about the new tab with the two licenses nodes : It looks very nice, but you cannot subscribe these license reports to generate an automatic email (yet)... There still an annoying bug with the filter option on many pop-up pages... The problem is, if you don't know there is a filter button outside the actual windows you can reach while playing with tab key, you cannot apply your filter... It has always been here in Edgesight 5.x versions... (I will post more detail about that tomorrow) Next blog about Edgesight will be all architecture I've deployed for different customers

Citrix XenApp 6 Sets New Standard in On-Demand App Delivery for Physical and Virtual Desktops New Release Simplifies Management, Enhances Scalability and Expands High-Definition Support for Macs, Smart Phones and Microsoft Platforms 3/10/2010 » SANTA CLARA, CA » Citrix Systems, Inc. (NASDAQ: CTXS), today announced Citrix® XenApp™ 6, the de facto standard for centralizing applications in the datacenter and delivering them as an on-demand service to both physical and virtual desktops. XenApp 6 offers major new enhancements that simplify computing for IT, including easier central management, enhanced enterprise scalability and seamless integration with Microsoft technologies like App-V and Windows Server 2008 R2. XenApp 6 also improves productivity for end users with extensive new high-definition HDX™ technology enhancements and simplified self-service access to apps from any device, including PCs, Macs, laptops and smart phones. The new enhancements to XenApp 6 will also be available as an integrated feature of the company’s comprehensive desktop virtualization solution, Citrix XenDesktop™ 4. Mainstream adoption of desktop virtualization requires a proven, scalable solution with the ability to deliver any type of virtual desktop to any user on any device, and to be able to interchange delivery technologies at any time. With more than half the ROI of virtual desktops coming from centralized app management, this integration provides an unparalleled advantage over any other desktop virtualization solution on the market today. This powerful combination makes it easy for customers to deliver apps as an on-demand service to any user, on any device, across a broad range of both physical and virtual desktops. Bill Burley, Group Vice President and General Manager, XenApp Product Group at Citrix “Citrix XenApp 6 delivers an entirely new level of IT simplification and user experience that goes beyond anything we’ve ever done with XenApp. The new simplified management capabilities and increased scalability reduce the cost of application management by up to 50 percent for both physical and virtual desktop environments. Combined with Citrix Dazzle, the self-service enterprise app store, and broad new support for Macs, laptops and smart phones with Citrix Receiver, customers can now deliver apps as an on-demand service to any user in any location at a fraction of the cost of traditional application management.” Garth Fort, General Manager of System Center Marketing, Server and Tools Business at Microsoft Corp.   “With support for Windows Server 2008 R2 in XenApp 6 and new integration with Citrix XenApp and Microsoft App-V, we…

In this post I explain how I tried to troubleshoot this issue, if you need the solution, go at the end of this post. My company (Activlan) had to renew our certificate installed on our Citrix Secure Gateway 3.1.3. As you might know, Citrix has issued some virtual appliance and I had to chose between, Citrix Access Gateway 4.6.2 VPX and Netscaller VPX Express (Free !). My choice was to integrate a Citrix Access Gateway (CAG) mainly because we are using other product to manage VPN to all our customers and I wanted to install what I needed, nothing less, nothing more. So here we go, I got my xva file from MyCitrix account and I just deploy it on our XenServer, very easy, very simple, just some clicks. Once installed and basics configuration set, I had to generate the CSR (Certificate Signing Request) and wait for Verisign to send me the certificate I had to use with the CAG. This was a big adventure and of course I should have read the manual before, and configuration isn't so easy but I guess when you do it all day long you begin to know everything and I can say now, I know how to troubleshoot a CAG from the client side to the Web Interface. This error I got with my Mac didn't show up on my Windows computers. In fact Apple doesn't have a very big list of root certificate install on their OS compare to Windows. Here is the error message I got when I wanted to launch published application (XenApp). I was able to login in the CAG and the Web Interface as well, but not able to launch application. SSL Error 61: You have not chosen to trust "Verisign Class 3 Secure Server CA - G2", the issuer of the server's security certificate. Error number: 183 Sexy message, isn't it ? After searching around a bit I found this thread on Citrix's forums : http://forums.citrix.com/message.jspa?messageID=447656 everything went clear, I didn't had the root certificate on my computer to validate my brand new certificate from Verisign... So I tried to find how to get these root certificates, especially Verisign Class 3 Secure Server CA - G2, the one I needed. I found this Verisign address http://www.verisign.com/repository/roots/pca_certificate.html where you just have to fill a form to get a zip with everything what you might need : As you…
