One SQL, lots of SharePoint 2010 Servers, and lots of Databases to clean

Question

I have a dedicated server running SQL server and many web servers running SharePoint 2010 installations. All the SharePoint web servers are using the same SQL server for storing/creating databases.

As I know, When SharePoint is installed it creates a collection of databases for itself to work (around 8 or 10).

Two Questions:

• How can I know which group of databases belong to which installation of SharePoint?
• When I uninstall SharePoint, the databases remain on the SQL server, how do I clean SQL from a removed/uninstalled SharePoint installation?

Thanks,

Answer 1

Found a way to do it, using the PowerShell:

• Go to Start => All Programs => Microsoft SharePoint 2010 Products => SharePoint 2010 Management Shell.
• Type the Command: Get-SPDatabase

The list of DBs for the SharePoint installation will be shown to you.
