Create and run SQL Server Agent jobs on Linux
SQL Server jobs are used to regularly perform the same sequence of commands in your SQL Server database. This tutorial provides an example of how to create a SQL Server Agent job on Linux using both Transact-SQL and SQL Server Management Studio (SSMS).
- Install SQL Server Agent on Linux
- Create a new job to perform daily database backups
- Schedule and run the job
- Perform the same steps in SSMS (optional)
For known issues with SQL Server Agent on Linux, see the Release Notes.
The following prerequisites are required to complete this tutorial:
- Linux machine with the following prerequisites:
The following prerequisites are optional:
- Windows machine with SSMS:
- SQL Server Management Studio for optional SSMS steps.
Enable SQL Server Agent
To use SQL Server Agent on Linux, you must first enable SQL Server Agent on a machine that already has SQL Server 2017 installed.
To enable SQL Server Agent, follow the step below.
sudo /opt/mssql/bin/mssql-conf set sqlagent.enabled true
Restart SQL Server with the following command:
sudo systemctl restart mssql-server
Starting with SQL Server 2017 CU4, SQL Server Agent is included with the mssql-server package and is disabled by default. For Agent set up prior to CU4 visit, Install SQL Server Agent on Linux.
Create a sample database
Use the following steps to create a sample database named SampleDB. This database is used for the daily backup job.
On your Linux machine, open a bash terminal session.
Use sqlcmd to run a Transact-SQL CREATE DATABASE command.
/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -Q 'CREATE DATABASE SampleDB'
Verify the database is created by listing the databases on your server.
/opt/mssql-tools/bin/sqlcmd -S localhost -U SA -Q 'SELECT Name FROM sys.Databases'
Create a job with Transact-SQL
The following steps create a SQL Server Agent job on Linux with Transact-SQL commands. The job runs a daily backup of the sample database, SampleDB.
You can use any T-SQL client to run these commands. For example, on Linux you can use sqlcmd or Visual Studio Code. From a remote Windows Server, you can also run queries in SQL Server Management Studio (SSMS) or use the UI interface for job management, which is described in the next section.
Use sp_add_job to create a job named
Daily SampleDB Backup.
-- Adds a new job executed by the SQLServerAgent service -- called 'Daily SampleDB Backup' USE msdb ; GO EXEC dbo.sp_add_job @job_name = N'Daily SampleDB Backup' ; GO
Call sp_add_jobstep to create a job step that creates a backup of the
-- Adds a step (operation) to the job EXEC sp_add_jobstep @job_name = N'Daily SampleDB Backup', @step_name = N'Backup database', @subsystem = N'TSQL', @command = N'BACKUP DATABASE SampleDB TO DISK = \ N''/var/opt/mssql/data/SampleDB.bak'' WITH NOFORMAT, NOINIT, \ NAME = ''SampleDB-full'', SKIP, NOREWIND, NOUNLOAD, STATS = 10', @retry_attempts = 5, @retry_interval = 5 ; GO
Then create a daily schedule for your job with sp_add_schedule.
-- Creates a schedule called 'Daily' EXEC dbo.sp_add_schedule @schedule_name = N'Daily SampleDB', @freq_type = 4, @freq_interval = 1, @active_start_time = 233000 ; USE msdb ; GO
Attach the job schedule to the job with sp_attach_schedule.
-- Sets the 'Daily' schedule to the 'Daily SampleDB Backup' Job EXEC sp_attach_schedule @job_name = N'Daily SampleDB Backup', @schedule_name = N'Daily SampleDB'; GO
Use sp_add_jobserver to assign the job to a target server. In this example, the target is the local server.
EXEC dbo.sp_add_jobserver @job_name = N'Daily SampleDB Backup', @server_name = N'(LOCAL)'; GO
Start the job with sp_start_job.
EXEC dbo.sp_start_job N' Daily SampleDB Backup' ; GO
Create a job with SSMS
You can also create and manage jobs remotely using SQL Server Management Studio (SSMS) on Windows.
Start SSMS on Windows and connect to your Linux SQL Server instance. For more information, see Manage SQL Server on Linux with SSMS.
Verify that you have created a sample database named SampleDB.
Verify that SQL Agent was installed and configured correctly. Look for the plus sign next to SQL Server Agent in the Object Explorer. If SQL Server Agent is not enabled, try restarting the mssql-server service on Linux.
Create a new job.
Give your job a name and create your job step.
Specify what subsystem you want to use and what the job step should do.
Create a new job schedule.
Start your job.
In this tutorial, you learned how to:
- Install SQL Server Agent on Linux
- Use Transact-SQL and system stored procedures to create jobs
- Create a job that performs daily database backups
- Use SSMS UI to create and manage jobs
