I've never seen that not work.
When you open the jobs up in Management Studio and go to Notifications, does it still say "On Completion" or does it say "On Failure"?

I build my own tool for this purpose.
I have a database called DBA that has tools in it for DBAs. One of the tools has these objects:

If it's less than 100 rows, use a table variable. If it's more, use a temp table. That's the simple version.
Really, it's not quite that simple, and the...

Keep in mind that tracking the last time something was updated is only good for knowing if the row has been refreshed recently. It doesn't tell you how often...

I once saw a performance improvement with and OLTP database on RAID-5 when the files were split in two and some of the most commonly used indexes were moved into...

I'm curious, I must admit, about the connection between the title and the actual post. What do missing records have to do with performance tuning? Same for non-responsive...

I think I must be missing the point. Why would you run something for a weekly notification, but run it every hour?
