SharePoint TIP: working with the farm property bag

Farm Property Bag

List farm properties	$farm = Get-SPFarm $farm.Properties.GetEnumerator() | Sort Name | fl -Auto or (Get-SPFarm).GetEnumerator() | Sort Name | fl -Auto
Add a farm property	$farm=Get-SPFarm $farm.Properties.Add("[name]", "[value]") $farm.Update()
Set a farm property	$farm.Properties["[name]"] = $value $farm.Update()
Remove a farm property	$farm.Properties.Remove("[name]") $farm.Update()

Notes

• Properties are stored in Hash-Table (Key-Value) format.
• Not case-sensitive.
• Same approach is used at the web application, site collection, web and list levels.  Each of these has a "Properties" collection.  For web application properties, you would use a web application object, for site collections, get an instance of the site collection object, and so on.
• I have found that some SharePoint solution (e.g., farm solution) providers add properties to the farm properties bag for internal sharing of licensing information.
• Properties must be added as key-value pairs.
