Virtualization Strategies for the CIOCitrix has chosen PowerShell as their scripting and development platform for XenApp. This has lead to the creation of the XenApp cmdlets; providing the administrator with a wealth of power. Follow these steps for installing and configuring cmdlets and learn the many ways these scripts can be utilized to simplify day-to-day administrative tasks.

PowerShell
automation for Windows Server 2008. You should also be aware that XenApp cmdlets require XenApp
4.5 with Hotfix Rollup Pack 3 (HRP3) and above. This is primarily due to the fact that the .NET
classes the cmdlets were built on are not available prior to HRP03.
XenApp cmdlets must also be installed on a XenApp server. Citrix made a conscience decision to rely on PowerShell remoting. This was primarily a performance and quality control decision.
The XenApp cmdlets are still in CTP so you will need to have a MyCitrix account. This account is free and you can sign up while following the download link.
Install
After you download MSI the install is as simple as a double click. This will start the installer.
Step through the wizard and it will register the snap-in, as well as create the shortcut (figure
1).

Configure
By default, the snap-in is installed but the registered PowerShell does not load it. Therefore, you
will need to take an extra step to make this happen. You have two options:
- Load the snap-in on demand: Add-PSSnapin Citrix.XenApp.Commands
- Add the above command to your profile.ps1 file so it is loaded every time.
Utilizing XenApp cmdlets
Getting the farm
Getting the farm information is done with two different cmdlets. The first cmdlet is
Get-XAFarm (figure 2) and is used for getting the farm object which provides general
information about the farm .The second cmdlet is Get-XAFarmConfiguration (figure 3) which is
used to get the farm configuration information.

Getting applications
To get application information, use Get-XAApplication (figure 4). To list the application
configuration information, including users and groups, use the cmdlet
Get-XAApplicationReport (figure 5).

Getting XenApp server information
There are two cmdlets for getting server information. Get-XAServer (figure 6) is used for
getting basic information about the server. Get-XAServerConfiguration (figure 7) gives
detailed information about the XenApp Server.

Now that the XenApp cmdlets are downloaded, installed and configured you are ready to get started using these cmdlets to manage your farm and make your day-to-day adminstrative life easier.
