I'd used a private "DBA" database for years until my latest position which involves a large farm of database servers dedicated to a prominent third party ERP software product. Man, I had used that database for maintenance procedures, backup jobs, growth tracking, the works. When I suggested creating one on each of the servers for this purpose I suddenly had a very quiet room and the undivided attention of an angry mob. To paraphrase and summarize the answer: "No."
Actually, the long and complete answer: "No." <LOL>
Nice solution, though; good work!
