Concepts
Step 1: Provision Elastic Job Agent
Before you can create and configure elastic jobs, you need to provision an Elastic Job Agent. This agent serves as the execution framework for your jobs. You can provision it through the Azure Portal, PowerShell, or Azure CLI.
Step 2: Create Job Credential
Next, you need to create a credential that defines the security context for the T-SQL script execution. This credential should have the necessary permissions to perform the required tasks across the targeted databases. You can create the credential using T-SQL or PowerShell.
Step 3: Create Job Category
Job categories are used to group related jobs together. You can create a job category to categorize your elastic jobs based on their functionality. This step is optional but can help organize and manage your jobs effectively.
Step 4: Define Job Target Groups
A job target group represents a set of databases on which you want to run a job. You can define the target group based on attributes such as database name filters or elastic database tags. This allows you to selectively choose the databases on which a job will be executed.
Step 5: Create Job
Now, you can create a job and associate it with a job category and target group. A job consists of a T-SQL script that defines the actions to be performed on the databases. You can create a job using T-SQL, PowerShell, or the Azure portal.
Step 6: Schedule and Execute Job
After creating the job, you can define a schedule for its execution. You can schedule the job to run immediately, at a specific date and time, or based on a recurring pattern. Once scheduled, the job agent executes the T-SQL script on the target databases as per the defined schedule.
Step 7: Monitor Job Execution
You can monitor the execution of your jobs using various methods. The Azure portal provides a comprehensive overview of job status, history, and execution details. You can also use T-SQL queries to gather job execution statistics and track progress.
Step 8: Manage and Modify Jobs
Elastic jobs offer flexibility in managing and modifying your existing jobs. You can pause, resume, or delete jobs as per your requirements. You can also modify job schedules, target groups, or job scripts whenever necessary.
Here’s a sample code snippet in T-SQL to create an elastic job agent:
USE msdb;
GO
-- Create an elastic job agent
DECLARE @jobOwnerId uniqueidentifier;
SET @jobOwnerId = dbo.[SystemJobInfo]('OwnerLoginId');
EXEC dbo.sp_add_jobserver
@job_name = N'ElasticJobAgent',
@owner_sid = @jobOwnerId;
-- Verify the job agent creation
SELECT * FROM dbo.sysjobs;
These are the basic steps to create and configure elastic jobs in Azure SQL. By effectively utilizing elastic jobs, you can automate and streamline your administrative tasks, saving time and effort.

Great post on creating and configuring elastic jobs! Very helpful for my DP-300 preparation.
Can someone explain the best practices for scheduling jobs in an elastic job agent?
Sure! It’s important to stagger the jobs to avoid resource contention, and use partitioning to handle large data sets more efficiently.
Also, make sure to monitor the job activity and adjust the schedules based on the workload patterns.
Thanks for the detailed instructions. I was able to set up my first elastic job successfully.
I appreciate the step-by-step guide. Made things much clearer for me!
What’s the difference between elastic jobs and SQL Server Agent jobs?
Elastic jobs are designed to work at scale across multiple databases, while SQL Server Agent jobs are more suited for single server environments. Elastic jobs also provide more flexibility in terms of scheduling and execution.
To add, elastic jobs can be managed in the Azure portal and can target databases across different servers, which is not possible with SQL Server Agent jobs.
This blog post was a lifesaver! I was struggling with configuring the credentials.
Is there any way to monitor the performance of the elastic jobs?
Yes, you can use Azure Monitor to track the performance and logs for elastic jobs. It’s quite powerful for diagnostics.
Additionally, setting up alerts can help you proactively manage any issues that arise.
Just wanted to say thanks for the awesome guide!
