Are there any tools built into Domino 7 or 8 that an Administrator can use to find inactive or unused databases?
Subject: Find inactive databases
I am not sure about inbuilt functionality but you can either
check the database Catalog.nsf if “List in database catalog” is enabled for all your databases. Chek for the item value “DbActSummDisp”
Or you can programatically find it using the “useractivity” class, if Record activity for the databases is enabled. The class is available at http://www-10.lotus.com/ldd/sandbox.nsf/ecc552f1ab6e46e4852568a90055c4cd/c12a2fd2142758b68525688d00708397?OpenDocument
