databases are weirdly mechanical in that you have to shut them off now and then to sort of straighten out the rows and columns, and chuck out abandoned or corrupted files.. maybe add some grease in the form of optimizations and then fire it back up so users can get it all messy again inside.. mostly because they're all written just well enough to function..
How do you straighten out rows and columns?
just give the tape drives a little jiggle as they come online
That doesn't sound right. Why would turning a database off let it do anything? It's off. Most databases periodically do stuff like this in the background.
