These last days I had to find out what was wrong with an extranet publish through XenApp. This extranet is using java and the issue users reported was random disconnection with a java popup. Find out what is wrong with extranet application is very hard because this is just a published browser with an URL pointing to a website in another company, everything works well until one day… My goal was to bring as much information and details as possible to the extranet’s support team and I needed to use the java console and grab the most verbose log possible.

First you need to publish the Java Control Panel,

Many new features have been updated with XenApp 6 Technical Preview (Project Parra), UPM, Merchandising Server, Single Sign On, SmartAuditor. I will show you in the post the main part (for me) User Profile Manager 3 Tech Prev, a bit about Merchandising Server 1.2 and Single Sign On 4.8.

User Profile Manager 3 Tech. Prev.

Here is a list of new featured inluded in this TP

• Citrix streamed user profiles. With Citrix streamed user profiles, files and folders are synchronized on the local computer only when they are needed, which speeds up logon and logoff. (Registry entries are cached immediately.) This feature includes the following settings in the ADM file.
• Cache entire profile. Profiles are synchronized locally after logon as a background system task, without any feedback to users.
• Active profile write back. Files and folders (but not Registry entries) that are modified can be synchronized to the user store in the middle of a session, before logoff.
• More supported operating systems. Windows 7 and Windows Server 2008 R2 are now supported.
• Diagnostic enhancements. Administrators can now set the computers and groups to be monitored using the Diagnostic Facility in the Daily Management Console. They no longer have to configure logging in the ADM template and force a group policy update (that they may not have permissions for). In addition, new event log messages display the full path to the user store for each user logon.
• For further deployment information, including how to add the ADM file in the download to Group Policy, see the installation topics in the Version 2.1 documentation.
• Installation enhancements. Profile management checks for more errors during installation and, if they are encountered, writes messages to the event log. A new command-line switch installs Profile management without the .ini files that were previously used for configuration.

You can see bellow installation screenshots :

The Citrix XenApp 6 Technical Preview is now available and works fine, even if there are some “bugs” I haven’t notice yet a BIG problem. Anyways, XenApp 6 is the most important component of this new release because it goes along with Microsoft Windows 2008 R2, but there are many other new stuff like WebInterface 5.3, Single Sign On 4.8, User Profile Manager 3, unified administration console (Yes !), Merchandising Server 1.2 and many other things Sridhar Mullapudi list in his post here : http://community.citrix.com/display/ocb/2009/12/15/XENAPP+SNEAK+PEEK+-+XenApp+for+Windows+Server+2008+R2

I will bring some lights about what you can find in the 2,5Gb iso file and compare what’s new and different with what we are use to administrating every day.

More users, faster logons- Get up to 20% more users per server with XenApp on the R2 platform and faster logons with new Profile management streaming technology that improves user profile load times by up to 80%.

I need  a XenServer at home to work on some project for my company (Activlan), I don’t want a real server because it would be too noisy in my apartment So I’m looking for a silent computer and I think I made it with the element bellow :

• Case : Lian Li PC-V351B
• Power Supply : Silverstone Nightjar ST45NF – 450W
• MotherBoard : Asus Maximus II Gene
• Cpu : Intel® Core™ 2 Quad Q9550
• Ram : G.Skill Extreme Series MQ 4×4096Mo PC6400 Dual Channel CAS6
• Video : PNY Quadro NVS 295 PCI-E 16x (for another workstation #XD4)
• Hard Drive : Seagate Barracuda ES.2 S-ATA – 1000 Go – 32 Mo (x2)

I think it should work fine, just some question remains : The network adapter on the Asus motherboard might not be compatible with XenServer and I choose two hard drive to build a RAID 1 but I’m affraid XenServer won’t be able to recognize the sata RAID controller. So we’ll see… If anyone have an experience with this material, please let me know !

Citrix release today the first update for XenServer 5.5 :

Changes included in this update
LVHD Snapshots
When LVHD snapshots are deleted, disk space is reclaimed by freeing unused snapshot data. This is provided automatically by XenServer while VMs continue to run. However, there is a known limitation in the 5.5 implementation of this feature: when all snapshots are deleted for a given VM?s disks, some disk space allocated to these snapshots may remain. To address this limitation, Update 1 includes an ‘Off-line Coalesce’ tool that can reclaim all disk space previously allocated to deleted snapshots while the VM is temporarily set offline. The Off-line Coalesce tool and its use are described in full in an associated KB article: CTX123400.

XenCenter Improvements
CA-30569, CA-32164, CA-30200

Fixed various ‘Application Errors’ in XenCenter.

 

CA-32241

XenCenter saved searches are now visible under ‘Apply Saved search’ and ‘Delete saved search’ options.

 

CA-33918

Big improvements to XenCenter performance when connecting to multiple pools.

 

 

Storage
CA-30577

Snapshot errors after upgrade from 5.0 to 5.5. Previously released as hotfix XS55E001 and documented in KB article CTX122142.

 

CA-24607

When multipathing is disabled, then this information is now correctly displayed in XenCenter.

Here it is ! We were waiting for this one since few month now and Citrix just release the Technical Preview for XenApp on Microsoft Windows 2008 R2, XenApp 6.

Few things you need to know before beggining to test : Windows 2008 R2 is and will remain only 64bit OS. XenApp 6 can be install only on Windows 2008 R2.

I begin this insallation on a clean naked Windows 2008 R2 without any update. You can check teh system requirements here : http://support.citrix.com/proddocs/topic/xenapp6-w2k8-tp/ps-system-requirements-w2k8-xa6.html

First, few screenshots of the new installation interface to describe the installation process.

DotNet 3.5 Sp1 is updated as soon as the installation beggins, after a new white interface very easy to understand popup and you can choose between reading some more information about what you’re going to install or adding roles to your server.
