VBScript to Start BizTalk Orchestrations

This blog contains a sample VBScript to start a BizTalk Orchestration

The SDK (Software Development Kit) of BizTalk includes a sample to stop orchestrations.
“c:\Program Files (x86)\Microsoft BizTalk Server 2010\SDK\Samples\Admin\WMI\Stop Orchestration\VBScript\StopOrch.vbs”
I guess, since it is just a sample, they chose not to provide the opposite to “Start” orchestrations.

I was having to deploy just a .DLL, not entire MSI over and over, so I started to make a script to do it. I need to stop the orchestration, run BTSTask with the AddResource option, then start the orchestration.

The trick is that you have to Enlist it before Starting it. So I run both the .Enlist and the .Start methods, one right after the other. I removed the optional UNENLIST parm.

Below is the VBScript:

<pre>
'--------------------------------------------------------------------------
'
' ScriptName: StartOrch.vbs 
' WMI script to start a specific orchestration.
' Neal Walters - 02/10/2016 took StopOrch.vbs in BizTalk SDK to make StartOrch.vbs 
'
'--------------------------------------------------------------------------
' This file is based on samples in the Microsoft BizTalk Server 2009 SDK

    Set objWMIError  = nothing
  End  If

</pre>

To run it:
cscript “VBScript\StartOrch.vbs” “ProjNamespace.OrchName” “AppName”
