Session reliability works at the client end. It allows a client to reconnect and avoid inconvenience to a user during a short network interruption. Instead of removing all unresponsive apps and desktops from the client workbench, they will be kept open until the ICA client is able to reconnect to the terminal server. It uses port 2598 and is available with Advanced and Enterprise versions.
Whereas ICA Keep-Alive works at the server end allowing a server to detect broken sessions and put them into a ‘disconnected’ state if it can’t ping the client device.
**How does IMA traffic get sent and processed amongst Citrix servers?
**Citrix has what we call a transport “function” that is responsible for getting packets of information from one host to another. The transport component is relatively small and does not actually care about the data it is transporting. This is a small set of functions for setting up bindings to host and subsequently sending packets to those hosts.
How does IMA know who the hosts in a farm are to ensure communication requests are from approved sources?
Command to know in which server is the Web Interface installed.
How to know in which server is the web interface installed?
ans: psinfo \\servername -s | find “web interface” ex: psinfo \\citrixservername -s | find “web interface”
If you have more number of servers, you can use the same command in a batch script and use it.
Some applications, such as CRM and CTI, use an IP address for addressing, licensing, identification, or other purposes and thus require a unique IP address or a loopback address in sessions. Other applications may bind to a static port, which, because the port is already in use, causes the failure of multiple attempts to launch an application in a multiuser environment. For such applications to function correctly in a XenApp environment, a unique IP address is required for each device.
In order to replicate or autoadd printer drivers to all our xenapp servers, use printer management in xenapp advanced configuration. Install the printer driver first into your xenapp server, using the printer management, replicate it to other xenapp servers.
We can also set autoreplicate option in printer management so that any new xenapp server added to this farm will get that printer drivers added automatically. In order to use autoreplicate feature, right click on the driver and choose autoreplication option.
1). Enter credentials at the Web Interface
2). Web interface reaches out to the XML broker, and passes the credentials
3). XML broker reaches out to AD Domain Controller, and authenticated credentials.
4). After being authenticated, user can request an ICA file for application launch
5). The best server will be selected based on load evaluators
6). Best server will respond back to the web interface with ICA file
7). ICA file is passed from Web Interface to client machine
While most applications can be successfully virtualized for use with SoftGrid, some applications may have certain characteristics that would prevent them from being completely virtualized using the current version of Microsoft SoftGrid. This includes:
Applications that install and rely on a system-level driver, i.e. an application that installs a print driver or a USB device driver. Some applications may allow for the drivers to be installed independent of the other components of the application.
Citrix XenConvert is a tool to migrate (P2V) physical (or virtual) Windows systems to XenServer.
XenConvert is similar to VMware Converter but without some of the advanced features and functions. XenConvert is installed and executed on the source system and only one local disk can be converted at a time. You must have 115% free space to convert a disk, the free space does not have to be on the same local disk, but it cannot be a mapped network drive.
XML
The XML service handles all client communication. Client communication like user authentication to the published app list, resolving the Citrix Zone Preference Policies, user application requests, and user connections requests. The XML service also hosts the Secure Ticket Authority that is used for storing secure tickets for user session requests and session reliability in case of a network interuption. Citrix Web Interface is considered a web-based client component, that can also be used in conjunction with Program Neighborhood Agent.
Hi All,
Thank you very much for your responses for my XenApp 6 Version 0 script. It just installs the executables on your server, but doesnt check if it is installed. So, I have designed another script which would install the softwares, checks if it is installed successfully and gives result.
Installation is exactly as same as for the version 0 (Click here for version 0), only the way in which softwares are installed is changed a bit.
