We ware asked to enable a new rule that site/sub site cannot be deleted if any document declared as record. Of course I have added new web deleting event receiver and used a web scoped feature to register the event on web.
But we have more than 100000 sub sites in our SharePoint farm. And enabling web scoped feature for all existing sites became a risk and performance hit.
I had created two scripts to resolve this issue. 1. PS script to collect all site collection from a web application and store it in a XML file. 2. PS script will read the XML file and process the site collection one by one as we got a provision to pass number site to be processed at one time. It reduced the performance hit and trace issue if any feature failed to activate
