There appears to be a collection of tables in our MSDB database taking up a some 3.5GB of space. These tables are all prefixed with DTA_ (i.e. DTA_reports_index, DTA_reports_indexcolumn) and so I assume were created as part of some prior database tuning exercise?
Is there a way I can safely flush the content of these tables, or preferably remove them as they are taking up space unnecessarily on a production server.
Any advice you can provide is most appreciated.
Many Thanks,
John
