Analyzing SQL Agent Job and Job Step History in SQL Server

Problem
Almost every DBA configures SQL Agent Jobs for automation of repetitive tasks. This valuable facility works in the background in SQL Server and saves a lot of effort and manual rework. You may have a number of jobs scheduled and often there is the need to analyze the data to see which jobs are taking a long time or which job steps are taking a long time. As you add more jobs and overhead to the server these times become even more critical and analyzing the data is key. SSMS offers some insight into your jobs, but there is no easy way to slice and dice the data to see what is going on for a particular job or at a particular time of the day.

Some of the questions you may want to ask include:

  • How much difference in performance is there for the current scheduled time compared to changing the time to midnight?
  • Exactly how much time is consumed now to complete the job?
  • Have jobs performed better after changes or there is some negative impact?
  • Which step of a specified job is taking longer than it takes normally to complete?

Questions like these require analysis performed over the history of the jobs. So how do you generate the required set of data in a form that is suitable for analysis? Or a situation where someone does not have access to SSMS or EM to access the job history for verification and analysis?

Asynchronous Socket Programming in C#

Image
Objective The objective of this article is to demonstrate a socket-based client/server application that will allow two-way asynchronous communication between a server and multiple client applications. Because this example uses asynchronous methods, the server application does not use threads to communicate to multiple clients (although internally the asynchronous communication mechanism uses threads at the OS level). The Difference Between Synchronous and Asynchronous Communication in Network Programming The key difference between synchronous and asynchronous communication can be explained with an example. Consider a server application that is listening on a specific port to get data from clients. In synchronous receiving, while the server is waiting to receive data from a client, if the stream is empty the main thread will block until the request for data is satisfied. Hence, the server cannot do anything else until it receives data from the client. If another clien
