Default they are created in the master database, but you can change it to the msdb database, or to a dba utility database if you prefer that.
The second option is used to tell the script if you want it to automatically create SQL Server Agent jobs for you that are pre-configured, and ready to run, although they still need to be scheduled. If you don’t want the script to automatically create the jobs for you, then replace ‘Y’ with ‘N’.
If you ever feel uneasy when you set about handcrafting database maintenance jobs for SQL Server, it may be the voice of your conscience saying 'Ola, Ola! Why reinvent something that does it all, safely and well. After a new SQL Server instance is created, one of the first tasks the DBA must undertake is to create a database maintenance plan.
Ola Hallengren has already crafted a superb set of routines to do this for you.
While it is possible to create a decent database maintenance plan using the Maintenance Plan Wizard (see my free e Book: Brad’s Sure Guide to SQL Server Maintenance Plans), the tool is not very flexible, and if it isn’t properly used, it can result in poor database maintenance.
Another common way for more experienced DBAs to create database maintenance plans is to create custom T-SQL or Power Shell scripts to perform database maintenance.
Ola Hallengren is a DBA and database developer who is currently working with a large financial company in Sweden. Back in 2007, Ola began a project to improve the database maintenance within a large SQL Server environment.
At that time, a combination of database maintenance jobs created using the SQL Server Maintenance Wizard, along with a collection of custom Transact-SQL scripts, were used throughout the organization.
Fortunately, this is not the case, because there are many DBAs who have written generic database maintenance scripts that are much more flexible and powerful than those created with the Maintenance Wizard.
Since then, he has improved his script on a regular basis, and it is now being used by some of the largest organizations in the world.
