Configuring Auto-Retry on SQL Server Agent

The goal of this post is to explain how to take advantage of Auto-Retry and why you will want to use it. I hope to clarify in which circumstances an auto-retry works best and when not to use it also. The (disclaimer!) point is that every job has its own constraints, requirements, and has to be evaluated individually for whether an auto-retry will work. I will try and keep this summary short and crisp, but still with enough detail to understand auto retry best.

This paper outlines what it took: the software, hardware, and configuration used. We will describe what we did to achieve that result, and offer suggestions for how to relate these techniques to typical scenarios.
