SQL Agent jobs starting simultaneously.
Why should you care about them?
Multiple SQL Server Agent jobs are configured to start simultaneously, which will not perform as fast as if jobs would not overlap.
Your SQL Server may be under heavy load for short bursts of time.
By the way, this check is a part of our SQL Server Health Check service.
How can I find the SQL Server jobs that start simultaneously?
You can use the script below to list all Agent SQL Server jobs starting at precisely at the same time.
SELECT j.name As JobName,
j.description AS JobDescription,
a.start_execution_date AS JobStartExecutionDate
FROM msdb.dbo.sysjobs j
INNER JOIN msdb.dbo.sysjobactivity a ON j.job_id = a.job_id
WHERE j.enabled = 1 AND a.start_execution_date IN
(SELECT start_execution_date
FROM msdb.dbo.sysjobactivity
GROUP BY start_execution_date HAVING COUNT(*) > 1)
How to fix them?
- Spread job execution tweaking the job schedules.
