Explaining ICA Session Reliability, Common Gateway Protocol, on TCP Port 2598. Preparation; Delivery Controller Install. Create Site; Second Controller; Delivery Controller Updates. Delivery Controller Hotfixes Update 3; PowerShell. Is it possible to run Unified Gateway behind this solution? I also want to use Citrix Receiver adn Receiver for WEB with this solution, possible? Citrix Policy Settings Citrix PVS: Optimize endpoint with Power. Shell. With Citrix PVS the content of a disk is streamed over the network to an endpoint. This requires sufficient bandwidth and an optimized configuration. If both criteria are not met the endpoint suffers from delays, retries or failures. Frequently asked questions for Tricerat software support. These steps are recommended when ScrewDrivers Server cannot be removed with Add or Remove Programs. Version 2.8.300 resolves known delays during user logon. Performance improvements in. A number of best practices apply when using Citrix PVS, most of them probably apply for your situation. In the past I had to optimize my VM’s manually each and every time I had to create a new v. Disk! Ain’t nobody got time for that (link)! I wrote a Power. Shell script that optimizes the endpoint for Citrix PVS and would like to share it with you. Updated on June 1. Applied best practices. The script applies a number of best practices to optimize the performance of the PVS endpoint. Some are enabled by default, some are not. Disable Task Offload. The most generic best practice that applies for (almost) every PVS environment, disabling all of the task offloads from the TCP/IP transport. See also CTX1. 17. Disable IPv. 6Although Citrix is working hard to get IPv. Citrix products, PVS does not support IPv. Disabling IPv. 6 on your PVS endpoints prevent intermittent failures. For each network adapter the IPv. This utility is included in the download. Also, slow boots could occur due to IPv. See also this Tech. Net article. Disable TSO and DMA on Xen. Tools. When you’re running your PVS endpoints on Citrix Xen. Server 5. 0 or 5. This is a known bug that’s solved in (a hotfix of Xen. Server 5. 6). Increase UDP Fast. Hpcmpmgr.exe software is installed. Send threshold. For every UDP packet larger than 1. Windows network stack waits for a transmit completion interrupt before sending the next packet. Unlike for earlier releases, v. Sphere 5. 1 does not provide a transparent workaround of the situation. See also KB2. 04. Set multiplication factor to the default UDP scavenge value. High CPU usage occurs when a Windows Server 2. R2- based server is under a very heavy UDP load. This issue occurs because a table is too aggressively scavenged. See also KB2. 68. Icons are hidden. To prevent users from accessing system tools like the PVS target device software or VMware tools the icons are removed. Disable VMware debug driver. The virtual machine debug driver was disabled for this virtual machine message displays in event log. The virtual machine debug driver is not required in an ESX host. The driver is used for record/play functions in Fusion and Workstation products. See also KB1. 00. Receive Side Scaling is disabled. VMXNET3 resets frequently when RSS is enabled in a multi v. CPU Windows virtual machine. When Receive Side Scaling (RSS) is enabled on a multi v. CPU Windows virtual machine, you see Net. Port messages for repeating MAC addresses indicating that ports are being disabled and then re- enabled. See also KB2. 05. Remove non- present NICs. After removing a network adapter – for instance to replace an E1. Windows machine. The network adapter is not visible in device manager (see KB2. IP stack and, most likely, has a higher priority. As a result the PVS target device software is unable to communicate with the streaming server. All Ethernet adapters that are not present on the machine are removed using the Dev. Con utility. The utility is included in the download, in case you lost it make sure you use version 6. Windows 7 WDK for x. Default setting: Enabled Network Adapter specific optimization. For each network adapter (E1. TCP offloading. Depending on the network adapter this has different names and some have more than one feature to disable. Default setting: Enabled. The script changes the following sets the following properties: Network Adapter. Property. Value. E1. VMware)Large Send Offload (IPv. Disabledvmxnet. 3 (VMware)IPv. Giant TSO Offload. Disabled.

All known properties and values are provided in the script, all you have to do is uncomment (removing the #- character) and set the value you want. The default value is 3 (Tx and Rx Enabled), to disable the feature you need to set the value to 0. In case your missing a hypervisor (or a version) feel free to contact me at . Within the script you can enable / disable the features in the global options section (eg removing hidden NIC’s or unbinding IPv. If wanted you can set advanced NIC properties by uncommenting the statement and providing the new value. The script is best executed before the v. Disk is uploaded but can also be run in Private mode (starting v. You can download the files here. Optimize. PVSendpoint. Thanks. I would like to thank the following people who where kind enough to test the script and provide me with feedback and test data: Kees Baggerman – link. Wilco van Bragt – link. Iain Brighton – link.

Navigation. It does not include settings that are native to Microsoft group policies. See the VDA Group Policies articles. However, they are not portable, meaning that you can. If you use the GPO method, make sure the GPOs are linked to OUs that contain VDAs. CTP Carl Webster et al compiled a complete list of 4. Citrix Group Policy Settings at Group Policy Settings Reference for Citrix Xen. App and Xen. Desktop. Login to a machine (e. Controller) that has Group Policy Management. If this machine doesn’t have Citrix Studio installed then install the Citrix Group Policy component from the \x. Citrix Policy folder on the Xen. App/Xen. Desktop 7. Make sure all Group Policy consoles are closed first. Citrix sometimes releases updates for this component, so whenever you update your Delivery Controllers. Note: Citrix (Daniel Feller Xen. Desktop 7. 7 and Windows 7) has found that the High Server Scalability template can increase user density by 3. On the Policies. Below the policy, click the Settings tab. As you edit the policy settings, make note of the Applies to field. Some of the settings do not apply to Virtual Delivery Agent 7. Also notice that some settings apply to Desktop OS (virtual desktop) or Server OS (Remote Desktop Session Host) but not necessarily both. Read the Applies to section to verify.

Click Add next to the setting Client USB device redirection. Change the selection to Allowed and click OK. This is the last generic setting. See the next couple sections for more settings. Citrix Policy Templates. The Citrix Policies node of a GPO (or Citrix Studio) has a Templates tab. Each of these templates has pre- defined settings that you can use as a basis for new policies. Citrix recommends only enabling it for users on lossy connections with high bandwidth. More details in the Framehawk Virtual Channel Administrator Guide at docs. In either case you need the updated Group Policy Management 2. Hotfix 2. 2. 9 included in Xen. App 7. 1. 1) on the machine where you are editing the policy. If configuring a GPO, you. This is the same process as enabling DTLS for UDP Audio. Note: there are limitations of Framehawk with Net. Scaler Gateway. For example, HA, App. Flow, and double- hop are not supported. Open this between the Net. Scaler SNIP and the VDAs. VDA 7. 8 and newer opens these ports automatically. VDA 7. 6. 3. 00 and VDA 7. Graphics. EDT improves HDX/ICA performance across WAN links, Internet, etc. In 7. 1. 2, EDT was Tech Preview. In 7. 1. 3, EDT is officially supported. EDT has several requirements: In 7. Policy Setting. Install the Intel Graphics Drivers before installing the VDA. If VDA is already installed, run. To see them, set the middle drop- down to All Settings and then search for clipboard. The setting Readonly clipboard does not apply to 7. Instead, review the three clipboard settings below it. Or you can turn off clipboard altogether by setting Client clipboard redirection to Prohibit. Under File Redirection is a setting for Read- only client drive access. This allows client drive mapping but prevents files from being copied to the client device. For VDAs in Legacy Graphics Mode, the following ICA/HDX protocol tuning options should be evaluated to optimize bandwidth consumption and virtual desktop resource utilization: User \ ICA \ Desktop UI \ Desktop Wallpaper = Disable. User \ ICA \ Desktop UI \ Menu animation = Disable. User \ ICA \ Desktop UI \ View window contents while dragging = Disable. User \ ICA \ Multi Stream Connections \ Multi- Stream = Enable (and Qo. S)User \ ICA \ Printing \ Direct connection to print servers = Disable. User \ ICA \ TWAIN devices \ TWAIN Compression Level = High. User \ ICA \ Visual Display \ Target Frames per Second = 1. User \ ICA \ Visual Display \ Moving Images \ Minimum Image Quality = Low. User \ ICA \ Visual Display \ Still Images \ Extra Color Compression = Enabled in very low bandwidth scenarios.
