Schedule Ola Hallengren’s Maintenance Solution (T-SQL Scripting Series)


If you have you ever struggled with setting up a maintenance plan for SQL Server, you’ll be glad that Ola Hallengren came around. This very clever SQL Server DBA thought, well the SQL Server Maintenance Plans aren’t that great. It does the job, but out of the box some jobs are scheduled at exactly the same time, amongst other inefficiencies. We all can be thankful that he wrote his own MaintenanceSolution.sql, which has won several awards and can be downloaded for free here.

F5 and then?

If you have downloaded Ola Hallengren’s MaintenanceSolution.sql, you still have to schedule the SQL Agent Jobs. But it is logical that this is not included, as every company, every server could have different requirements for backup, integrity checks, index optimization and statistics maintenance.

.. Configure!

In the script below you will find a CONFIGURATION section where you can configure how the SQL Agent Jobs created by Ola Hallengren should be scheduled. Just for your convenience, hope you like it.

    1. Hello Vitalic, thank you for letting me know. It is always good to know that my blog post has helped somebody. Thanks.

    1. thanks for your script !

      Could you tell me how to configure the script for INTEGRITY CHECK please ?
      If I want to schedule it every month first sunday, for example, I don’t know how …
      Best regards 🙂

      1. Hi Ben,
        Thanks for your message.
        There are two things important:
        1) What is the jobname you want to schedule?
        2) The scheduling itself.
        1) You can check the correct jobname easily in SQL Server Management Studio if you have installed Ola’s solution. Then copy the name into the script.
        2) My script does not really cater for monthly schedules, so either you schedule the integrity check weekly (which might not be a bad idea) or create a schedule with SQL Server Management Studio.
        Hope this helps.
        Best regards,
