Chapter 3 Using View PowerCLI
Examples of Using View PowerCLI for Enhanced Functionality
You can create PowerShell functions by combining View PowerCLI and vSphere PowerCLI cmdlets to perform
complex operations such as resizing pools, and adding datastores to desktop pools. The following sections
contain sample functions that you can adapt and apply to your own systems.
Checking if a View Connection Server Instance Is Running
Define a PowerShell function to check if a View Connection Server instance is running, and optionally, start
the service.
# WaitForViewStartup
# Parameters
# $ClearError If $true, clear the $error object on completion.
# $StartBroker If $true, start the service if it is not running.
function WaitForViewStartup
{ param ($ClearError = $true, $StartBroker = $true)
$service = Get-Service wsbroker
if($service -and (Get-Service wstomcat)){
$started = $false
if($service.Status -eq "Stopped"){
if($StartBroker){ # Start the broker if it is not running.
Write-Warning "Connection Broker service is stopped, attempting to start."
$errCountBefore = $error.Count
Start-Service wsbroker
$errCountAfter = $error.Count
if($errorCountAfter -gt $errorCountBefore){
break
}
} else {
Write-Error "Connection Broker service is stopped."
break
}
}
while(!$started){ # Loop until service has completed starting up.
Write-Warning "Waiting for View Connection Server to start."
$errCountBefore = $error.Count
$output = Get-GlobalSetting -ErrorAction SilentlyContinue
$errCountAfter = $error.Count
$started = $true
if($errCountAfter -gt $errCountBefore){
$err = $error[0].ToString()
if($err.Contains("NoQueueHandler")){
$started = $false
Start-Sleep -s 1
} else {
if($ClearError){
$error.Clear()
}
Write-Error $err
break
}
}
if($ClearError){
$error.Clear()
}
}
} else {
Write-Error "The View Connection Server services could not be found. Is the Connection
Server installed?"
}
}
