SUMMARY

This article describes the following about this hotfix release:
  • The issues that are fixed by the hotfix package
  • The prerequisites for installing the hotfix package
  • Whether you must restart the computer after you install the hotfix package
  • Whether the hotfix package is replaced by any other hotfix package
  • Whether you must make any registry changes
  • The files that are contained in the hotfix package

SYMPTOMS

After you restart a computer that is running Microsoft SQL Server 2005, the following problems may occur:
  • When SQL Server starts, an application query that reads lots of data as soon as the query connects may be slow.
  • The SQL Server service may take a long time to start.
Note These problems do not occur in Microsoft SQL Server 2005 Enterprise Edition, in Microsoft SQL Server 2005 Developer Edition, or in Microsoft SQL Server 2005 Evaluation Edition.

CAUSE

These problems occur because some types of intensive front-end application queries may have long compilation waiting times when SQL Server starts. The long compilation waiting times occur when application metadata is populated in the SQL Server buffer pool.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2005 Service Pack 1.

MORE INFORMATION

This hotfix exposes trace flag 840. When trace flag 840 is turned on, SQL Server can perform larger I/O extent reads to populate the buffer pool when SQL Server starts. The larger I/O extent reads populate the buffer pool faster. Additionally, the larger I/O extent reads improve the initial query compilation and the response time when SQL Server starts. For more information about how to turn on trace flag 840, see the "Using the SQL Server service startup options" topic in SQL Server 2005 Books Online.

Note SQL Server 2005 Enterprise Edition, SQL Server 2005 Developer Edition, and SQL Server 2005 Evaluation Edition can already perform 64-KB I/O extent reads during buffer pool ramp-up. Therefore, you do not have to apply this hotfix to SQL Server 2005 Enterprise Edition, to SQL Server 2005 Developer Edition, or to SQL Server 2005 Evaluation Edition.
