This is the definitive guide to troubleshooting the Microsoft SQL Server 2005 database engine, direct from the people who know it most intimately: the people who wrote it, designed it, and support it. SQL Server expert Ken Henderson, author of the best-selling Guru’s Guides to SQL Server, has assembled a “dream team” of SQL Server developers and support engineers to provide in-depth troubleshooting and diagnostic information that has never been documented before: information that would be impossible to get without access to Microsoft’s own source code.

From caching to clustering, query processing to Service Broker, this book will help you address even the toughest problems with database engine operations. Each chapter begins with a brief architectural overview of a key SQL Server component, then drills down into the most common problems users encounter, offering specific guidance on investigating and resolving them. You’ll find comprehensive, in-depth chapters on

• Waiting and blocking

• Data corruption and recovery

• Memory

• Procedure cache issues

• Query processing

• Server crashes and other critical failures

• Service Broker

• SQLOS and scheduling

• tempdb

• Clustering

This is the indispensable resource for everyone who must keep SQL Server running smoothly: DBAs, database application developers, API programmers, and Web developers alike.

The authoring team is a mix of developers from the SQL Server development team and support professionals from Microsoft’s Customer Support Services organization. Seven developers from the SQL Server development team and three support professionals from Microsoft CSS contributed to this book.

SQL Server Development Team

August Hill has been a developer for more than 30 years. For the past six years he has been a member of the SQL Server Service Broker team. He’s made a number of contributions to the product in the area of supportability. When he’s not developing software he can be found playing guitar or tasting Washington wines.

Cesar Galindo-Legaria is the manager of the Query Optimizer group in SQL Server. He received a Ph.D. in computer science (databases) from Harvard University in 1992. After working for a graphics company in the Boston area, he went back to databases, doing post-doctoral visits in European research centers. In 1995 he joined Microsoft to work on a new relational query processor, first shipped with SQL Server 7.0, which introduced a fully cost-based query optimizer, a rich set of execution algorithms, and a number of auto-administration features. He has been working on query processing for SQL Server ever since. He holds several patents on query processing and optimization, and has published a number of research papers in that area.

Ken Henderson has been a developer for more than 25 years. He has worked with SQL Server since 1990 and has built software for a number of firms throughout his career, including H&R Block, the Central Intelligence Agency, the U.S. Navy, the U.S. Air Force, Borland International, JP Morgan, and various others. He joined Microsoft in 2001 and is currently a developer in the Manageability Platform group within the SQL Server development team. He is the creator of SQL Server 2005’s SQLDiag facility and spends his days working on SQL Server management tools and related technologies.

He is solely responsible for the infamous “non-yielding scheduler” error messages that support professionals have come to abhor! He is currently a software development lead in the SQL Server Security team. In his spare time, Sameer enjoys being outdoors and going on long bike rides. He lives with his wife Farhat in the Seattle area.

Santeri Voutilainen, better known as Santtu, has been a software design engineer in SQL Server storage engine team since 1999. He has worked closely on page allocation, latches, and the lock manager.
