SQL Agent Job: Determine how long it has been running

Question

The Scenario

There are certain SQL Agent Jobs that are scheduled to run every few minutes throughout the day.

There are legitimate times when it

Answer 1

What you're doing manually sounds like what's known as a "watch dog loop". Basically, an SQL job that starts and/or monitors agent jobs, killing them if need be.

The code below was taken from here, and should help, removing the need for you to manually monitor and kill jobs if they've been running for a lengthy period of time:

/****************************************************************
--This SQL will take a list of SQL Agent jobs (names must match),
--start them so they're all running together, and then
--monitor them, not quitting until all jobs have completed.
--
--In essence, it's an SQL "watchdog" loop to start and monitor SQL Agent Jobs
