The Configuration Logging feature allows you to keep track of administrative changes made to your server farm environment. By generating the reports that this feature makes available, you can determine what changes were made to your server farm, when they were made, and which administrators made them. This is especially useful when multiple administrators are modifying the configuration of your server farm. It also facilitates the identification and, if necessary, reversion of administrative changes that may be causing problems for the server farm.
Prerequisites:
The following pre-requisites are required to install and operate Desktop Studio:
Microsoft Management Console (MMC) 3.0
Microsoft PowerShell 2.0
Microsoft .Net Framework 3.5 SP1
This is not platform specific and can be installed using the XenDesktop media at Support\DotNet35SP1\dotnetfx35.exe or using Windows Update.
Microsoft Shared Management Objects 2008 R2
This can be installed using the XenDesktop media at:
Support\SharedManagementObjects\x**\
where x** is the platform (x86 or x64).
It is important to select the correct version for your operating system.
Where multiple administrators make modifications to a XenApp farm, Citrix recommends implementing Configuration Logging. By tracking the changes that each administrator has made to the system and correlating any subsequent issues reported, it is easy to identify any modifications that may need to be rolled back.
For example, if an administrator changes the properties of a published application at 10:00 and help desk associates escalate issues related to multiple sessions being launched by users, it would be simple to correlate that the modification impaired session sharing.
Image Compression Policy Settings The Image compression section contains settings that enable you to remove or alter compression. When client connections are limited in bandwidth, downloading images without compression can be slow.
Extra color compression This setting controls the degree of extra color compression used on images delivered over client connections thta are limited in bandwidth, improving responsiveness by reducing the quality of displayed images. When enabled Extra Color Compression is applied only when the client connection bandwidth is below the Extra Color Compression Threshold value.
Working with Load Evaluators These load evaluators are included in Load Manager:
Default. Load Manager attaches the Default load evaluator to each server after you add your license to the server farm. It contains two rules: Server User Load, which reports a full load when 100 users log on to the attached server; and Load Throttling, which specifies the impact that logging on has on load and limits the number of concurrent connection attempts the server is expected to handle.
Profile management ensures that the user’s personal settings are applied to the user’s virtual desktop and applications, regardless of the location and end point device.
Profile management is enabled through a profile optimization service that provides an easy, reliable way for managing these settings in Windows environments to ensure a consistent experience by maintaining a single profile that follows the user. It auto-consolidates and optimizes user profiles to minimize management and storage requirements and requires minimal administration, support and infrastructure, while providing users with improved logon and logout.
About Secure Gateway:
The Secure Gateway for Windows helps you to secure access to enterprise network computers running Citrix XenApp and provides a secure Internet gateway between Citrix XenApp and user devices. The Secure Gateway transparently encrypts and authenticates all user connections to help protect against data tampering and theft. All data traversing the Internet between a remote workstation and the Secure Gateway is encrypted using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol.
When a GPU is normally present on a physical workstation, this is a great way to accelerate the performance of these applications on a desktop computer. When you’re using these products in a virtual desktop environment, things change slightly. All of the major virtual desktop solutions (VMware View, Citrix XenDesktop and Microsoft RDVH) enable a software GPU in the virtual desktop session when their VM enlightenment drivers are installed into the virtual desktop image.
Below are the values for load manager:
0 to 9998: This is the normal range for Load Manager.
9999: No load evaluator is configured.
10000: Load is at 100 percent (full load).
20000: The Presentation Server Console contains an incorrect server edition or a license mismatch.
99990: Results when a custom administrator with restricted rights runs the following QFARM commands:QFARM SERVER /APP QFARM /APP QFARM /APP <appname> QFARM /ZONEAPP
Note: The QFARM command may not return any results when a custom administrator runs the following queries:
Session initialization
No matter how an ICA session is invoked (Program Neighborhood, Web Interface, double-clicking an ICA file, etc.), the ICA client engine (wfica32.exe for Win32 clients) fires up and loads the module.ini file from the root folder of the ICA Client. The module.ini file defines the specific capabilities that the ICA client should or can use. Therefore, when troubleshooting, it’s possible (and useful) to change settings in the module.ini to change the capabilities of the ICA Client.
