INTRODUCTION

This article contains information about the Maintenance Plan Wizard in Microsoft SQL Server 2005. This article also describes the tasks that you can perform in SQL Server 2005 if you are an administrator who manages databases in the following products:

  • Microsoft Office SharePoint Server 2007
  • Microsoft Office SharePoint Portal Server 2003
  • Microsoft Windows SharePoint Services 3.0
  • Microsoft Windows SharePoint Services 2.0


MORE INFORMATION

The Maintenance Plan Wizard in SQL Server 2005 enables administrators to perform the following maintenance tasks against SharePoint databases:

  • Check database integrity
  • Reduce a database
  • Reorganize an index
  • Clean up the history
  • Update statistics
  • Rebuild an index

We have tested these tasks and the effects that these tasks have on database schema and performance. The following table summarizes the results of these tests.

Task Safe to perform this task?
Check database Yes
Reduce a database Yes
Reorganize an index Yes
Clean up the history Yes
Update statistics Yes. However, this task is unnecessary because the SharePoint Timer service performs this task automatically.
Rebuild an index No. The task does not restore existing index options before the rebuild operation. However, you can use scripts that restore index options.


Note This problem was corrected in SQL Server 2005 Service Pack 2.

We used the following criteria to determine whether a task was safe to perform:

  • Whether the task modified the database schema from its default state
  • Whether the task decreased performance

Results may vary depending on the environment. However, if you use the Maintenance Plan Wizard to perform the tasks that are listed in the table as "safe to perform," you are likely to experience increased performance in SQL Server 2005.
