If you want to learn about SQL Server 2005 and maybe win an XBox at the same time, sign up for Microsoft's free Webcasts, which start December 6 and end December 10. Microsoft will host three new Webcasts each day of the week, presenting 15 Webcasts in all. Topics include an overview of the new developer features in SQL Server 2005, an introduction to the new SQL Server Management Studio, T-SQL enhancements, XML in SQL Server 2005, ADO.NET 2.0 for SQL Server 2005, Service Broker, Reporting Services, Integration Services (formerly called Data Transformation Services—DTS), Analysis Services, and more. You can check the full schedule at http://msdn.microsoft.com/sql/2005webcasts/ . Then, starting in early January and running through SQL Server 2005's official release, Microsoft will begin a new series of SQL Server 2005 developer Webcasts. Microsoft plans to offer one new topic each week until SQL Server 2005 launches.
Matt Nunn, a SQL Server product manager, says everyone who attends a Webcast will receive the currently available SQL Server 2005 Beta 2 Resource Kit and the Beta 3 Resource Kit when it ships. Also, the first 1500 people to participate in 5 or more Webcasts will receive a special, limited-edition SQL Server 2005 Webcast t-shirt. And all Webcast viewers will be entered in the Microsoft SQL Server 2005 Developer Preview Webcasts Sweepstakes. Each day in a random drawing, Microsoft will select one person to win a Microsoft XBox system (see http://msdn.microsoft.com/SQL/WebcastRules.aspx for official rules).
I know that SQL Server 2005 is still a long time away from final release and you have a job to do today. However, SQL Server 2005 will introduce the most fundamental changes for SQL Server developers compared to any previous release of SQL Server technology. We'll get an entirely new development and management environment based on Visual Studio. And SQL Server 2005 will significantly change the way we build applications with its integration of native XML data type support and of the Common Language Runtime (CLR), along with a host of other development- and administration-oriented changes. Preparing a SQL Server 2005 rollout will be much more involved than the upgrade from SQL Server 6.5 to 7.0 or the upgrade from SQL Server 7.0 to 2000. There's no way you can become familiar with all these new features and technologies overnight, so if you want to be ready for SQL Server 2005 when it hits the market next summer, you need to begin updating your SQL Server skills today. And participating in these Webcasts, presented by the SQL Server developers who are building the new release, is a great place to start.

In SQL Server 2000, each database contains at least one data file and one transaction log file. If the transaction log file that corresponds to a SQL Server database is filled and you've set the option for the transaction log files to grow automatically, the transaction log file might become very large and you might run out of disk space. When a transaction log file grows until the log file uses all the available disk space and can't expand any more, you can no longer perform any data modification operations on your database. Additionally, SQL Server might mark your database as suspect because of the lack of space for the transaction log expansion. The Microsoft article "How to stop the transaction log of a SQL Server database from growing unexpectedly" shows you the steps to follow when the transaction logs expand to an unacceptable limit and provides the options that you can use to stop the transaction logs from growing unexpectedly.

SQL Server tools report performance information in different ways based on how they calculate the metrics they measure. In most cases, minor discrepancies in the data that different SQL Server tools report don't matter. However, wrong answers lead to poor query-tuning decisions. And you can get a wrong answer if you're using Query Analyzer to analyze I/O for a query that includes a user-defined function (UDF).

VERITAS Software announced VERITAS i3 7.1, application-management software that lets IT administrators simultaneously compare performance and availability characteristics of complex applications over clusters and multiple instances. Like previous releases, VERITAS i3 7.1 comprises three parts: Insight, Indepth, and Inform. Of particular interest to SQL Server professionals is Indepth for SQL Server, which monitors and captures transactions as they enter and exit the database, letting you analyze details of performance. For example, you can capture a single transaction and analyze where it's consuming the most resources, then fix the problem before end users notice a slowing of performance. In addition, the latest release has a repertoire of more than 225 reports for sending performance information to management and developers. And the product's alerting function lets you know about hot spots that develop over time so that you can address performance problems before they affect your users' experience. VERITAS i3 7.1 is designed to work with SQL Server 2000 Service Pack 3 (SP3), and pricing for a 4-CPU environment starts at $9200. For more information and pricing details, contact VERITAS at 650-527-8000 or 800-327-2232.
