can execute and schedule tasks and jobs.

Configuring Jobs
A job is a specified series of operations performed sequentially
by SQL Server Agent.
• A job can perform a wide range of activities, including running
Transact-SQL scripts, command-line applications, Microsoft
ActiveX scripts, Integration Services packages, Analysis
Services commands and queries, or Replication tasks.
• Jobs can run repetitive tasks or those that can be scheduled,
and they can automatically notify users of job status by
generating alerts, thereby greatly simplifying SQL Server
administration. *

• T-SQL scripts
• PowerShell scripts

Configuring Jobs
USE msdb ;
GO
EXEC dbo.sp_add_job
@job_name = N'Weekly Sales Data Backup' ;
GO
EXEC sp_add_jobstep
@job_name = N'Weekly Sales Data Backup',
@step_name = N'Set database to read only',
@subsystem = N'TSQL',
@command = N'ALTER DATABASE SALES SET READ_ONLY', @retry_attempts = 5,
@retry_interval = 5 ;
GO
EXEC dbo.sp_add_schedule
@schedule_name = N'RunOnce',
@freq_type = 1,
@active_start_time = 233000 ;
USE msdb ;
GO
EXEC sp_attach_schedule
@job_name = N'Weekly Sales Data Backup',
@schedule_name = N'RunOnce';
GO
EXEC dbo.sp_add_jobserver
@job_name = N'Weekly Sales Data Backup';
GO
Creating Operators
An Operator is the person to be notified when a certain action
or event occurs on SQL Server or SQL Server Agent.
Creating Operators
Creating Operators
• Only members of the sysadmin fixed server role can create operators.
• SQLAgentUserRole
• SQLAgentReaderRole
• SQLAgentOperatorRole
• Note that SQL Server Agent must be configured to use Database Mail to
send e-mail and pager notifications to operators.
• The Pager and net send options will be removed from SQL Server Agent
in a future version of Microsoft SQL Server. Avoid using these features in
new development work, and plan to modify applications that currently
use these features.
Creating Operators
-- sets up the operator information for user 'danwi.' The operator is enabled.
-- SQL Server Agent sends notifications by pager from Monday through Friday from 8
A.M. to 5 P.M.
USE msdb ;
GO
EXEC dbo.sp_add_operator
@name = N'Dan Wilson',
@enabled = 1,
@email_address = N'danwi',
@pager_address = N'5551290AW
@pager.Adventure-Works.com',
@weekday_pager_start_time = 080000,
@weekday_pager_end_time = 170000,
@pager_days = 62 ;
GO
Creating Alerts
Alerts are automated notifications that are fired when certain
events are triggered.
• SQL Server event
• SQL Server performance conditions
• Windows Management Instrumentation(WMI) event
Windows Management Instrumentation (WMI) is the infrastructure for management data and operations on
Windows-based operating systems. You can write WMI scripts or applications to automate administrative tasks
on remote computers but WMI also supplies management data to other parts of the operating system and
products, for example System Center Operations Manager, formerly Microsoft Operations Manager (MOM), or
Windows Remote Management (WinRM).
Creating Alerts
Creating Alerts
USE msdb
EXEC sp_add_alert
@name = 'Test Alert',
@message_id = 55001,
@severity = 0,
@notification_message = 'Error 55001 has occurred. The
database will be backed up...',
@job_name = 'Back up the Customer Database'
Creating Alerts
-- adds an e-mail notification for the specified alert (Test Alert)
-- This example assumes that Test Alert already exists and that
François Ajenstat is a valid operator name.
USE msdb ;
GO
EXEC dbo.sp_add_notification
@alert_name = N'Test Alert',
@operator_name = N'François Ajenstat',
@notification_method = 1 ;
GO
Creating Proxies
A SQL Server Agent proxy defines the security context for a job
step.
• A proxy provides SQL Server Agent with access to the security
credentials for a Microsoft Windows user. Each proxy can be
associated with one or more subsystems.
• A job step that uses the proxy can access the specified
subsystems by using the security context of the Windows user.
Before SQL Server Agent runs a job step that uses a proxy, SQL
Server Agent impersonates the credentials defined in the
proxy, and then runs the job step by using that security
context.
Creating Credentials
• Credentials provide a way to allow SQL Server Authentication
users to have an identity outside of SQL Server.
• Credentials can also be used when a SQL Server
Authentication user needs access to a domain resource, such
as a file location to store a backup
• A credential can be mapped to several SQL Server logins at the
same time. A SQL Server login can only be mapped to one
credential at a time.
