Moving your host configuration from one server to another can be daunting and time consuming task. This usually needs to be done when you hand over stuff from development to test, or from test to production. On those environments you mostly want to have the exact same host configuration as you have on your development box.
Another option is that a new development team member has just started on a fresh development box and you want him to use the same host configuration that you have. There are a lot of other scenarios where you want to copy the configuration of your hosts and host instances to another machine.
A lot of great BizTalk people have already showed how this can be done in an automated way. Some samples are:
- VBScript and WMI
- Custom tool 1
- Custom tool 2
In this post I want to show you how this can be done using PowerShell and the PowerShell provider for BizTalk. So this is actually the next post in my series on more advanced things you can do with the provider.
I use a slightly different approach compared to the existing tools. I use a PowerShell script that can be executed on the source server. This is the server that already has the host configuration set up, for example a development server. The output of running this script is actually another PowerShell script that you can run on the destination server. This output scripts contains all necessary statements to create the hosts, corresponding host instances and settings.
This is how it works:
- execute the script
- the script prompts for the name and path of the output file:
- after a short while the script is finished and a PowerShell script is created. You can run this script on the destination server or send it to an administrator who will run it on another server.
This is the created script:
#Determine BizTalk root and switch to host container.
$BizTalkRoot = (get-psdrive -PsProvider BizTalk).Root
Join-Path $BizTalkRoot 'Platform Settings\Hosts' | Set-Location
$RunningServer = $Env:ComputerName
#Create hosts
#Create host 'ReceiveHost' and set properties.
New-Item -Path 'ReceiveHost' -HostType 'InProcess' -NtGroupName 'BizTalk Application Users' -AuthTrusted:$False
Set-ItemProperty -Path 'ReceiveHost' -Name HostTracking -Value False
Set-ItemProperty -Path 'ReceiveHost' -Name Is32BitOnly -Value True
#Create host 'ProcessingHost' and set properties.
New-Item -Path 'ProcessingHost' -HostType 'InProcess' -NtGroupName 'BizTalk Application Users' -AuthTrusted:$False
Set-ItemProperty -Path 'ProcessingHost' -Name HostTracking -Value False
Set-ItemProperty -Path 'ProcessingHost' -Name Is32BitOnly -Value True
#Create host 'SendHost' and set properties.
New-Item -Path 'SendHost' -HostType 'InProcess' -NtGroupName 'BizTalk Application Users' -AuthTrusted:$False
Set-ItemProperty -Path 'SendHost' -Name HostTracking -Value False
Set-ItemProperty -Path 'SendHost' -Name Is32BitOnly -Value False
#Create host 'TrackingHost' and set properties.
New-Item -Path 'TrackingHost' -HostType 'InProcess' -NtGroupName 'BizTalk Application Users' -AuthTrusted:$False
Set-ItemProperty -Path 'TrackingHost' -Name HostTracking -Value True
Set-ItemProperty -Path 'TrackingHost' -Name Is32BitOnly -Value False
#Switch to host instances container.
Join-Path $BizTalkRoot 'Platform Settings\Host Instances' | Set-Location
#Create host instances
#Create host instance 'Microsoft BizTalk Server ReceiveHost BTS2K9-DEV' and set properties.
$Credential = $Host.UI.PromptForCredential('Host Instance user credentials', 'Please enter credentials for host instance ''ReceiveHost''', '', '')
New-Item -Path 'hostinstance' -HostName 'ReceiveHost' -RunningServer $RunningServer -Credentials $Credential
Set-ItemProperty -Path 'Microsoft BizTalk Server ReceiveHost BTS2K9-DEV' -Name IsDisabled -Value False
#Create host instance 'Microsoft BizTalk Server ProcessingHost BTS2K9-DEV' and set properties.
$Credential = $Host.UI.PromptForCredential('Host Instance user credentials', 'Please enter credentials for host instance ''ProcessingHost''', '', '')
New-Item -Path 'hostinstance' -HostName 'ProcessingHost' -RunningServer $RunningServer -Credentials $Credential
Set-ItemProperty -Path 'Microsoft BizTalk Server ProcessingHost BTS2K9-DEV' -Name IsDisabled -Value False
#Create host instance 'Microsoft BizTalk Server SendHost BTS2K9-DEV' and set properties.
$Credential = $Host.UI.PromptForCredential('Host Instance user credentials', 'Please enter credentials for host instance ''SendHost''', '', '')
New-Item -Path 'hostinstance' -HostName 'SendHost' -RunningServer $RunningServer -Credentials $Credential
Set-ItemProperty -Path 'Microsoft BizTalk Server SendHost BTS2K9-DEV' -Name IsDisabled -Value False
#Create host instance 'Microsoft BizTalk Server TrackingHost BTS2K9-DEV' and set properties.
$Credential = $Host.UI.PromptForCredential('Host Instance user credentials', 'Please enter credentials for host instance ''TrackingHost''', '', '')
New-Item -Path 'hostinstance' -HostName 'TrackingHost' -RunningServer $RunningServer -Credentials $Credential
Set-ItemProperty -Path 'Microsoft BizTalk Server TrackingHost BTS2K9-DEV' -Name IsDisabled -Value False
There are a couple of things to mention about the generated script:
- This is by no means a script applicable for all situations and environments. The purpose is just to show the output script as a result of running the source script. The source script will probably need some modification to make it apply to your environment. For example the script does not take into account multi server configurations, etc.
- The output script will prompt for credentials for each host instance it will create. There are also ways to script this from source to destination. See for example here. In most cases hosts in different environments will run under different accounts which is why I choose to show a prompt each time.
- Also in this script the windows group for the host is kept the same for the destination environment. This might not be the case in your particular situation.
After running this script on the destination server I have a exact copy of my host environment on the source server.
The source script looks like this:
$ScriptFile = Read-Host 'Enter full path of script file:'</pre>
'#Determine BizTalk root and switch to host container.' | Out-File $ScriptFile
'$BizTalkRoot = (get-psdrive -PsProvider BizTalk).Root' | Out-File $ScriptFile -Append
'Join-Path $BizTalkRoot ''Platform Settings\Hosts'' | Set-Location' | Out-File $ScriptFile -Append
'' | Out-File $ScriptFile -Append
'$RunningServer = $Env:ComputerName' | Out-File $ScriptFile -Append
$BizTalkRoot = (get-psdrive -PsProvider BizTalk).Root
Join-Path $BizTalkRoot 'Platform Settings\Hosts' | Set-Location
'#Create hosts' | Out-File $ScriptFile -Append
$HostArray = @()
Get-ChildItem -Path . | Foreach-Object {
if (!$_.IsDefault -and $_.HostType -ne 'Isolated') {
$HostArray += $_.Name
"#Create host '$($_.Name)' and set properties." | Out-File $ScriptFile -Append
"New-Item -Path '$($_.Name)' -HostType '$($_.HostType)' -NtGroupName '$($_.NtGroupName)' -AuthTrusted:`$$($_.AuthTrusted)" | Out-File $ScriptFile -Append
"Set-ItemProperty -Path '$($_.Name)' -Name HostTracking -Value $($_.HostTracking)" | Out-File $ScriptFile -Append
"Set-ItemProperty -Path '$($_.Name)' -Name Is32BitOnly -Value $($_.Is32BitOnly)" | Out-File $ScriptFile -Append
'' | Out-File $ScriptFile -Append
}
}
'#Switch to host instances container.' | Out-File $ScriptFile -Append
'Join-Path $BizTalkRoot ''Platform Settings\Host Instances'' | Set-Location' | Out-File $ScriptFile -Append
'' | Out-File $ScriptFile -Append
Join-Path $BizTalkRoot 'Platform Settings\Host Instances' | Set-Location
'#Create host instances' | Out-File $ScriptFile -Append
Get-ChildItem -Path . | Foreach-Object {
if ($HostArray -contains $_.HostName) {
"#Create host instance '$($_.Name)' and set properties." | Out-File $ScriptFile -Append
"`$Credential = `$Host.UI.PromptForCredential('Host Instance user credentials', 'Please enter credentials for host instance ''$($_.HostName)''', '', '')" | Out-File $ScriptFile -Append
"New-Item -Path 'hostinstance' -HostName '$($_.HostName)' -RunningServer `$RunningServer -Credentials `$Credential" | Out-File $ScriptFile -Append
"Set-ItemProperty -Path '$($_.Name)' -Name IsDisabled -Value $($_.IsDisabled)" | Out-File $ScriptFile -Append
'' | Out-File $ScriptFile -Append
}
}
In the script I skip the default and isolated host. As with the generated output script this is just a sample and might not apply to your specific situation. The source script should be modified to confirm to your requirements and environment.
You can download the source script from here.
