Getting all automation connections from within SMA of a given type

I'm currently looking at how I can migrate some runbooks from System Center Orchestrator 2008 R2 to Service Management Automation (SMA). One issue I have in Orchestrator is that it isn't possible to subscribe to a configuration activity if you package it up into an Orchestrator Integration pack (OIP). To get around this, you can use the activity and call the Class directly from the DLL.

Why does it matter your thinking?  One scenario we have is that we want to be able to have a common runbook, and execute it against multiple load balancers. Each of these connections is then stored in Orchestrator.. and the caller passes the configuration name in (which is actually the lb hostname) and then it connects with the correct credentials.

Anyway I was thinking about how I could do the same or achieve the same in SMA, and realised that it was a non issue, I then started migrating some other runbooks, and one task requires running against all instances of an env.. for example VMWare - Go get all VM's across all vcenters..

I thought I'll just get all the connections of a given type and easy done, however Get-AutomationConnection has a mandatory parameter of the name.. and wildcards don't work.

I had a quick nosy in the database and realised it should be easy to do what I needed, so what I have done is create a workflow that queries the relevant table in the DB for the connections and then returns the name so you can use that to return the credential / connection pair required. This maybe achievable in other ways but I am new to SMA :)

The scripts are available here: Get-AutomationConnections.ps1 and an example of calling it here: UseMultipleConnections.ps1
