508 Chapter 14 Working with SQL Server Agent Jobs NOTE Can’t execute multiple tasks on same schedule Remember that when creating a maintenance plan, you are in essence creating an SSIS package, so you are defining the flow control definition within the SSIS package. However, you will not be executing multiple maintenance tasks on the same schedule, so this step in the wizard is superfluous. Depending on the maintenance task you select, the options that you can specify at this point in the wizard vary. If you select a maintenance plan for a database backup, you’ll see the option to select the databases to apply the task to, as shown in Figure 14-12. Figure 14-12 Specifying databases to back up After you select the check box for the databases you want to back up, click OK. You can then specify the folder in which you want to store the backups, along with whether you want to verify the backup integrity, as Figure 14-13 shows. Click Next. When you have specified all the appropriate task options, you can define a schedule, as shown in Figure 14-14. To access scheduling options, click Change.

The difference is that for a regular SQL Server Agent job, you can define multiple schedules for a regular job and reuse previ- ously created job schedules, but you can define only one schedule for a maintenance plan. Figure 14-15 Specifying scheduling options Click OK to close the New Job Schedule dialog box. After defining the schedule, you see a summary of the scheduling options displayed within the Maintenance Plan Wiz- ard, as Figure 14-16 shows. Click Next. For reporting purposes, you can configure each maintenance plan to write an out- put file or to e-mail the report about the actions it performs, as shown in Figure 14-17. You will usually specify writing to an output file that you can scan for errors. Click Next.

When you click Finish, the wiz- ard performs the following steps: 1. Generates an SSIS package. 2. Stores that SSIS package within the msdb database.

Creates entries in the sys.dbmaintplan* tables within the msdb database. Figure 14-18 Finishing maintenance plan creation Quick Check 1. What operations can a maintenance plan perform? 2. How many schedules can you apply to a maintenance plan? Quick Check Answers 1. A maintenance plan can back up databases, delete old backup files from the operating system, maintain indexes, execute another job, and shrink a database. 2. You can apply only one schedule to a maintenance plan. PRACTICE Create a Maintenance Job In this exercise, you will practice the creation of a maintenance plan to back up the AdventureWorks database. Instead of using the Maintenance Plan Wizard to create the maintenance plan, you will define it from a generic maintenance plan. 1. In SSMS, right-click the Maintenance Plans node in Object Explorer and choose New Maintenance Plan. C1462271X.fm Page 512 Friday, April 29, 2005 7:57 PM Lesson 2: Creating a Maintenance Plan 513 2. Specify a name for the maintenance plan and click OK. 3. Click the browser button (…) to the right of the Schedule text box. 4. Configure the maintenance plan to run once per day at 23:00, or 11:00 PM. When you’re done, click OK to close the Job Schedule Properties dialog box. 5. Click Connections to open the Manage Connections dialog box. Click Add and specify the server connection options. Click OK to save your changes and then click OK again to close the Manage Connections dialog box. 6. Click Logging and configure the logging options you want to use for this plan. 7. In the Maintenance Plan Tasks toolbox, drag and drop the Back Up Database Task onto the surface of the maintenance plan. 8. Double-click the Back Up Database Task and specify the AdventureWorks data- base to perform a full backup. Click OK to close the Back Up Database Task dialog box. 9. Drag and drop a Maintenance Cleanup Task onto the surface of the maintenance plan. 10. Select the Back Up Database Task. 11. Drag the green arrow from the Back Up Database Task to the Maintenance Cleanup Task, which creates a dependency between the two tasks so that the backup task runs first and the cleanup task runs second. 12. Double-click the Maintenance Cleanup Task and specify saving the backups for one day. When you’re done, click OK to close the Maintenance Cleanup Task dialog box. 13. Click Save on the toolbar to save your maintenance plan. Lesson Summary ■ A maintenance plan enables you to graphically configure SQL Server to perform one or more predefined maintenance tasks on a scheduled basis against one or more databases. ■ The most common type of maintenance plan that you will create is to back up a database on a regular basis. ■ Each maintenance plan is a monolithic SSIS package that can have only one schedule defined for it.

The questions are also available on the companion CD if you prefer to review them in electronic form. NOTE Answers Answers to these questions and explanations of why each answer choice is right or wrong are located in the “Answers” section at the end of the book. 1. What types of tasks can you define with the Maintenance Plan Wizard? (Choose all that apply.) A. Database creation B. Database backup C. Index rebuilding D. SSIS package execution C1462271X.fm Page 514 Friday, April 29, 2005 7:57 PM Lesson 3: Configuring Operators 515 Lesson 3: Configuring Operators The SQL Server Agent subsystem enables you to define operators to receive notifica- tions about jobs. You can use this mechanism to enable SQL Server Agent to send a notice when a job has failed, for example, alerting DBAs so that they can quickly eval- uate and repair problems. After this lesson, you will be able to: ■ Configure operators. Estimated lesson time: 10 minutes How to Configure an Operator You configure an operator by naming it and specifying various notification methods for the operator and other parameters, such as an e-mail address to send the notifica- tion to. To begin the configuration, in SSMS, right-click the Operators node below SQL Server Agent, and choose New Operator to define properties for an operator, as Figure 14-19 shows. Figure 14-19 Defining operator parameters C1462271X.fm Page 515 Friday, April 29, 2005 7:57 PM 516 Chapter 14 Working with SQL Server Agent Jobs Each operator needs a name. You then specify which notification methods—e-mail, net send, and pager—are valid for that operator. NOTE Enable the Messenger Service In order to use a net send, the Messenger Service must be enabled. You specify addresses or numbers for each valid notification method. In addition, you can configure an operator to receive notifications only during specific on-duty hours. NOTE Specifying a work week Unfortunately, the graphical user interface (GUI) assumes that the work week is Monday through Friday for everyone in the world. Selecting the Notifications page displays all jobs and alerts for which a particular oper- ator is configured to receive notifications. Click OK to create the operator. Quick Check ■ Which notification methods are valid for an operator? Quick Check Answer ■ You can notify an operator using net send, e-mail, or text messaging. Managing and Troubleshooting Jobs You can manage SQL Server Agent jobs within SSMS. To access the list of jobs that are configured on an instance, expand the SQL Server Agent node within SSMS, right-click the Job Activity Monitor item, and choose View Job Activity. The Job Activity Monitor displays a list of the jobs for the instance, along with the date and time the job was last run and the next date and time the job will run. The Job Activity Monitor also displays whether the job is enabled and whether the last run was successful. You can enable, disable, start, and stop a job by right- clicking it within the job activity grid. The shortcut menu also enables you to access the detailed history for a particular job, including any error messages that might have occurred during job execution. C1462271X.fm Page 516 Friday, April 29, 2005 7:57 PM Lesson 3: Configuring Operators 517 PRACTICE Configuring Operators In this practice, you will configure an operator to receive e-mail notifications. 1. Expand the SQL Server Agent node. 2. Right-click Operators and choose New Operator. 3. Specify a name for the operator. 4. Specify an e-mail address for the operator. 5. Click OK. NOTE Sending e-mail To send e-mail to this operator, you must enable and configure Database Mail. Because text mes- saging also relies on the mail subsystem, it also requires you to configure Database Mail. For infor- mation about configuring Database Mail, see Lesson 2, “Configuring Database Mail,” in Chapter 2, “Configuring SQL Server 2005.” Lesson Summary ■ SQL Server Agent enables you to define operators to receive notifications from jobs via e-mail, net send, or pager. ■ Operators provide a convenient way to refer to one or more messaging addresses by a single name. ■ To send e-mail or text messages, you need to have SQL Server Database Mail con- figured and enabled.
