From the article:

"After you get the users out of the system and lock it down so that you’re not contending with them (if there are connections into a database, you can’t restore it),"

Yes, there's the rub. How do you get the users out of the system and lock it down? We do not have a DBA here, so as senior programmer, I get to do most of these tasks. I haven't found a good explanation as to how to do this. Can someone enlighten me?

TIA,
