How to use PowerShell script variables?

[chadlockwood]

I have a PowerShell MID Server Script file, Out-MyNameIs.ps1:

[CmdletBinding()]

Param(

      [string]$name

)

Write-Output "%%MyNameIs%%"

Write-Output "$($name)"

Write-Output "%%"

I expect the Output of a Run PowerShell workflow activity to look like this:

%%MyNameIs%%

Chad

%%

In the activity, I have selected Out-MyNameIs.ps1 in the Script file field. Since my script requires the $name parameter, I have created a simple JSON string to put in the PowerShell script variables field:

{

        "name" : "Chad"

}

I have replaced "name" with "$name" and "powershell_name"(based on comment in Run PowerShell activity definition), and have changed the $name parameter in the script to $powershell_param_name as it appears in the ecc queue:

<parameter name="powershell_param_name" value="Chad"/>

So far, all I have seen is:

%%MyNameIs%%

%%

Has anyone any experience with using PowerShell script variables that can help me get this working?

Thanks,

Chad

Hi chadlockwood,

In Service Now-->Mid Server--> Script Files can we write a power shell script to start a Run book on System Center Orchestrator and get response ?

Vinay,

I don't have any experience with System Center Orchestrator, however, I have not yet found a PowerShell script that I could not run through ServiceNow. I'm guessing that you would need to have the SCO module installed on your MID server, or otherwise be able to create an implicit remote connection to your SCO server then you could import any necessary SCO cmdlets into your MID server script file. Basically, if there is already a PowerShell cmdlet, or you can write PowerShell to accomplish it, you can do it from inside ServiceNow.

On a side note, are you going to be at Knowledge 16 and if so, would you be interested in getting ServiceNow administrators who use PowerShell together to share info and discuss pitfalls/successes? I feel like we need a subculture to emerge at Knowledge.

Regards,

Chad

Hi Chad,

Thanks for your response.

Well I am not attending the Knowledge 16, to attend need to cross overseas.

Surely will be part of Administrator sub group. I support.
