Question

I have a Powershell script file called “ExecutBizTalkAppMSI.ps1” This contains a single function called “Install-BizTalkApplication”. I need to execute the function on a remote server, so I use the “Invoke-Command” cmdlet as follows:

Invoke-Command -Computer $TargetServer -FilePath .\ExecuteBizTalkAppMSI.ps1 -argumentlist $MSI, $InstallFolderOnTargetServer, $Environment

Problem is, although the target script runs (I added a Write-Host directly after the Param() section), the function “Install-BizTalkApplication” is not executed.

Can anyone please let me know what I need to do to make this happen?

Answer 1

I suspect the script looks like that:

# start
function Foo {}
# end

That won’t work. Two options:

• get rid of function name {} and run script as is
• define a function first, and run it as last step in a script

Example:

# script 1
param ($foo, $bar)
# function body...

# script 2
param ($foo, $bar)
function foo {
param ($foo, $bar)
# function body
}

foo -foo $foo -bar $bar
