1. SQL Server Perspectives

Windows XP SP2 Defaults Break SQL Server Connections
by Brian Moran, brian@sqlmag.com

If you're running Windows XP Service Pack 2 (SP2) and SQL Server, you've probably figured out that the XP SP2 default installation prevents most network access to SQL Server—including to Microsoft SQL Server Desktop Engine (MSDE). Fortunately, making SQL Server and XP SP2 coexist isn't difficult, and I'm here to provide resources that will make the task even easier for you.

The best place to start is with "FAQ: How Windows XP Service Pack 2 (SP2) Affects SQL Server and MSDE." This FAQ answers questions about how XP SP2 affects SQL Server and MSDE, how you can tell if your installations of SQL Server or MSDE are blocked, what to do if your application needs SQL Server to listen to the network, what you should do to update your SQL Server system, and where to find more technical information about getting XP SP2 to work with SQL Server and MSDE. You also need to review "How to enable SQL Server connectivity on Windows XP Service Pack 2," to learn how to set SQL Server as an exception in Windows Firewall. Finally, you should watch Richard Waymire's archived MSDN Webcast, "SQL Server and Windows XP SP2—Level 300." Bring your popcorn and settle in for 90 minutes. The Webcast presents a wealth of important SQL Server security information such as how to enable listening on the various network protocols and when you don't need to make any changes. This Webcast is a must-see for any SQL Server professional.

XP SP2 has many valuable new features, including a set of Microsoft-developed security technologies to help reduce the risk of malicious attacks against your computers. I'm particularly fond of Windows Firewall—an enhanced version of the component previously called Internet Connection Firewall. However, the Windows Firewall default installation is what blocks Internet access to SQL Server. Years of malicious worms and other Internet nasties have proven that our SQL Server boxes need to be locked by default. I don't have the space to describe the steps necessary to maximize the security capabilities of Windows Firewall while enabling users to access SQL Server across the Internet. The Microsoft article I mentioned earlier, "How to enable SQL Server connectivity on Windows XP Service Pack 2," gives all the details. But we all need to realize that the days of leaving Internet "front doors" open in case a neighbor stops by are over.

2. News and Views

  • TechEd 2004: SQL Server 2005 to Get Encryption, Decryption Features
    by Paul Thurrott, thurrott@winnetmag.com

    At TechEd 2004, Microsoft revealed that SQL Server 2005 will include native support for encryption, decryption, and key management. The idea is to provide a strong level of security directly in the product so that customers won't have to turn to third parties or rival database vendors. With this feature, even someone who successfully hacks into a SQL Server 2005 database won't be able to get data out of the database, Microsoft said. SQL Server 2005 will also undergo the National Information Assurance Partnership (NIAP) Common Criteria Evaluation and Validation Scheme (CCEVS) certification, which will ensure that the system is fit for use in the most secure government installations.

  • New BI Accelerators Available

  • Yesterday, Microsoft announced the availability of two new Microsoft Office 2003 Business Intelligence (BI) Accelerators: the Microsoft Office Business Scorecards Accelerator and the Microsoft Office Excel Add-in for SQL Server Analysis Services. The Business Scorecards Accelerator is a Web-based application that enables a company to simplify the measurement and management of key performance metrics to more easily communicate, drive, and measure business strategy. The Excel Add-in for Analysis Services is a flexible reporting and analysis tool that lets you access and analyze data directly in Excel. Both accelerators are now available for download at no additional cost to users who have valid licenses for the underlying Microsoft products.
    The Office Business Scorecards Accelerator is available at

  • Microsoft Fixes BizTalk Adapter Problem

  • Microsoft has released a hotfix for a looping problem with Microsoft BizTalk Server 2004. If a message fails validation or routing in BizTalk Server 2004, the BizTalk Adapter for SQL Server rolls back the transaction and leaves the failed message in the source SQL database. The SQL adapter will pick it up again and try to process it, but when the processing fails again, the transaction rolls back again. This problem creates a continuous loop. To learn more about the problem and the supported hotfix, read the Microsoft article "FIX: The BizTalk Adapter for SQL Server may repeatedly try to process a bad message" at http://support.microsoft.com/?kbid=841618.

  • What's New at sqlmag.com: Ranking Functions

  • T-SQL programmers have wanted a way to calculate row numbers and other ranking values in SQL Server for a long time. SQL Server 2005's new analytical functions let you write short and efficient code, compared to SQL Server 2000 alternatives, which are long, complex, and slow. In his June T-SQL 2005 column, "Ranking Functions," Itzik Ben-Gan describes three new analytical ranking functions in SQL Server 2005--RANK(), DENSE_RANK(), and NTILE().

  • Tip: Performing Usage-Based Costing

  • by Brian Moran, savvy@sqlmag.com

    Q. My company wants to charge application owners usage fees based on consumption of database resources, such as memory, CPU, I/O, the number of queries executed, and so on. Several third-party tools have this capability, but their data is based on sampling. We have many applications that run in less than 100ms, and a sampling approach misses much of this activity. Is there a comprehensive usage-based costing tool for SQL Server?

    A. Questions about usage-based costing are becoming more frequent as SQL Server penetrates deeper into the enterprise environment. Robust usage-based costing tools are common in the mainframe world, but SQL Server 2000 doesn't have a comparative feature. Linchi Shea, a SQL Server MVP who has real-world experience dealing with usage-based costing in a high-end SQL Server environment, has some valuable insights I'd like to share with you.

    SQL Server doesn't have a native accounting system that can provide basic, accurate, and persistent information you can use to calculate the charge-back amount, but there are many workarounds. Some techniques are cruder than others, but they all fall into one of two categories: those based on SQL Server Profiler and those based on sampling of master..sysprocesses. The trade-off is between using Profiler to get accurate, granular information but adversely affecting performance or getting less accurate data from sampling master..sysprocesses with minimal performance effects.

    For implementing an internal charge-back system, sampling master..sysprocesses is a better solution than using Profiler, especially if you're more concerned with charging proportionally for the SQL Server resources an application uses rather than charging for the application's absolute usage of SQL Server's resources. When building a charge-back system, you need to address many details-some business oriented and some technology focused. For instance, you need to answer the following questions:

    • What usage data do you use? Do you charge only for CPU utilization or a combination of CPU, memory, and I/O?
    • How do you collect and aggregate the usage data (e.g., by login, by database)?
    • How do you charge back usage to application owners--what is the formula you use to translate the raw usage data into the dollar amount you charge?
    • How do you ensure your charge-back infrastructure is reliable? If the usage-data collection component fails for an extended period of time, how do you deal with the gaps in your usage data?
    • Can your charge-back system provide an adequate answer if a customer questions a charge-back dollar amount? In other words, what kind of audit trail can you provide? Customers demand cost transparency.

    A good charge-back system is also a valuable performance-tuning tool. In distributed computing, developers commonly do whatever it takes to meet their release deadlines. Developers don't often worry about inefficient queries as long as the application works and no one complains too much about performance--even if they know that they could take steps to improve query performance. However, developers often improve their system's performance if they receive a huge monthly bill for resource usage, so a charge-back system can provide useful performance feedback into the development team.

    6. New and Improved


    (contributed by Dawn Cyr, products@sqlmag.com)

  • Simplify ADO.NET Application Development

  • Simplify ADO.NET Application Development Red Brook Software announced WiredNav 2.0, a self-wiring .NET control for filling, navigating, searching, updating, and reporting from ADO.NET data tables. Developers can use the control in database applications without making initial property settings or writing code. And the control requires no DataAdapter, DataSet, DataSource, or DataTable properties. At runtime, the navigator automatically wires itself to every data object on the Windows form you add it to. This feature means that you need only one navigator per form instead of one per data table. WiredNav includes features that improve data binding, currency management, and disconnected data handling. You can use WiredNav to print and view reports you create in SQL Server 2000 Reporting Services or Crystal Reports for Visual Studio .NET. You can use the control with SQL, Oracle, OLE DB, and ODBC data adapters. WiredNav supports SQL Server 2000 and costs $199. Contact Red Brook Software at 518-248-3450 or sales@redbrooksoftware.com.
