Foreword

Most books about SQL Server take one of the two approaches. The first approach is to provide a broad introduction to SQL Server administration. While overviews are great for beginners, they don't provide enough information, leaving the reader wanting for details and practical advice.

The second approach is to attempt to cover every possible topic the author can think of. While this may seem like a good approach, what generally ends up happening is that each topic doesn't get the attention it really deserves. And, in order to keep the length of the book reasonable (under 1,000 pages), a lot of practical details are left out, again, leaving the reader wanting for more.

As both a reader and author of many SQL Server books, I have discovered that the more focused the book's topic is, the more useful it becomes. This is why I like Satya SK Jayanty's new book, Microsoft SQL Server 2008 R2 Administration Cookbook. It offers over 70 practical recipes for managing and administering a high-performance SQL Server 2008 R2 system. So, instead of trying to cover every possible topic, the book, in effect, is a collection of more than 70 extremely focused books, each providing very specific and practical information on how to make the reader a better and more effective DBA.

Another thing I like about this book is that it is literally a recipe book. It walks with the reader, step-by-step, through each topic, leading the reader through the most difficult of topics. After reading each recipe, the reader will not only understand the importance of the topic, but will also be able to implement it themselves. Nothing is left to chance.

Of course, the book could not include practical information unless the author himself has been in the trenches and gotten his hands dirty. You are in good hands, as Satya is an accomplished SQL Server DBA with over 15 years of real world experience. While Satya has spent much of his career working for large organizations, what really separates him from many other authors is that he also spends a great amount of his personal time helping other DBAs.

In 2000, I started one of the first community-based SQL Server websites on the Internet. At first, I didn't have any forums on the website, because I knew I wouldn't have the extra time required to devote to answering questions, on top of all the time I was spending writing new content for the website. However, as the website became very popular, I finally added forums, hoping that I could find some DBAs in the SQL Server community who could help me answer questions. To my surprise, almost immediately one experienced DBA began answering questions on a daily basis, and ended up with over 5,000 posts the first year, and that DBA was Satya. I once asked him why he participated so much in the forums. And he told me that answering question was a great learning experience. So not only was he helping other DBAs by answering their questions, he was also learning more himself. This gives Satya a great insight into the minds of DBAs and the kinds of questions they may have, making him the perfect author for this book. As Satya began helping out in the SQL Server Community, all of his hard work was noticed by Microsoft and he was awarded the Microsoft SQL Server MVP award. In fact, he has been a SQL Server MVP for six years now, and he continues to help out in forums, speak at user groups and conferences, and he even maintains his own website.

As you read through the Microsoft SQL Server 2008 R2 Administration Cookbook, rest assured that the information you will learn will be first-rate and practical for your day-to-day work as a DBA. As you learn from Satya's experience, give some thought as to how you can get involved in the worldwide SQL Server community, and perhaps you can share your knowledge with others, just as Satya has with thousands and thousands of DBAs over the years.

SQL Server 2008 R2 Prologue

The different editions of SQL Server 2008 R2 adapt the unique performance, runtime, and price requirements of organizations and individuals. The SQL Server 2008 R2 data platform meets the need of handling structured data (transactional consistency) and offers relational capabilities to unstructured data by providing a solution that can store and manage many types of data, including XML, e-mail, calendar, media files, documents, geospatial, and many more, which provides a rich set of services to interact with the data and built-in capabilities of search, query, data analysis, processing, reporting, and integration from different data sources. The data accessibility feature is unlimited, whereby it accesses information on creation to archiving on any device, from a global data-center server to desktop or mobile devices.

A new version of SQL Server is related as Release To Manufacturing (RTM) version [(Microsoft SQL Server 2008 R2 (RTM)—10.50.1600] that comprises various enhancements as an end-to-end solution area for data platform. The key to the success of any database platform is dependent upon cost-effective and scalable database solutions. SQL Server 2008 R2 helps achieve these goals to deliver an enterprise class data platform to improve efficiency through better resource utilization, and build confidence in end users to scale out the application solutions.

To commence a scalable and high performance database platform design, identifying which SQL Server features are needed is a key aspect of design decision. The SQL Server installation wizard provides a feature tree for installation of various SQL Server components that includes management tools and connectivity components. The different services for SQL Server are independent of each other and run as dedicated services on a system. It is important to know the different services that are running on the core operating system:

Database Engine: SQL Server and SQL Server Agent are core database engine components that run as services.

SQL Server service: The Server service is useful for data management. It finds services to store and manipulate data based on the application requirement with a variety of backup and restore solutions. The database engine contains advanced security capabilities to lockdown, protect, and audit the data, in parallel with services to ensure high availability is achieved. For high performance and scalability arrangements, the SQL Server service is accountable to host a relational model service, which facilitates any changes to the data to keep up the transactional consistency to ensure that database will revert to a known consistent state in the event of a server or database failure.

SQL Server Agent: To automate essential administrative tasks, SQL Server Agent is essential. This service manages the information about scheduled jobs, monitors SQL procedures (performance objects), and processes alerts.

SQL Server Browser: Browser service works as a listener service to peruse a list of available servers and connects to a correct server instance. SQL Server Browser uses port 1434 to cater to a client request to SQL Server by sending a User Datagram Protocol (UDP) message; the task replies with TCP/IP or named-pipes protocol of installed instances. This is a key service to be used in emergency situations such as connecting to a SQL Server instance using Dedicated Administrator Connection (DAC) endpoints.

SQL Server Integration Services: Extract, Transform, and Load (ETL) activities are highly manageable and programmable using SQL Server Integration Services (SSIS). This service is capable of performing a variety of tasks to enable packages to import or export data from various file sources, manipulate files in operating system folders, or perform complex calculations inside database tables. A set of specialized tasks such as copy SQL Server objects or perform database backups or database maintenance operations can be designed as out of the box solutions using Visual Studio tools for Applications or the Business Intelligence Development Studio tool.

SQL Server Reporting Services: To design and manage a flexible platform for reports and data-distribution, SQL Server Reporting Services (SSRS) and tools are available. It creates a standardized methodology and builds complex reports so that the end user can obtain reports rapidly without having any knowledge of programming language or trying to understand the underlying complexity of the RDBMS platform. The SSRS is capable of configuring a report subscription to set up a schedule to execute the report and send it (by e-mail) to the preferred user distribution channel with their prescribed format specifications. The rendering capability to Portable Document Format (PDF) or Excel (XLS) format or Word format (.DOCX) is a highly advantageous feature for a DBA as it takes advantage of two main components—a report server and report designer.

SQL Server Analysis Services: Decision Support Systems can manage high volumes of data. Blending Business Intelligence features to the system can help us to manage data warehousing issues. The SQL Server Analysis Services (SSAS) is best used to cater the data needs of business users and the ability for IT to manage data efficiently. SQL Server 2008 R2 is built upon highly scalable systems to provide Online Analytical Processing (OLAP) and Data Mining capabilities. The data mart feature with SSAS extends the business analysis to allow the users to find patterns and predictions for their business values by utilizing several built-in mining algorithms.

Full-Text Search Service: Full-Text Search (FTS) consists of full-text indexing and a search engine, which is integrated into the core database engine. FTS is essential to perform a variety of tasks such as gathering data and sending it to the filter-daemon host for processing to 'tokenize' by a full-text gatherer. Once this is completed, SQL Server receives results to index them as an inverted index structure for optimized performance during a search function.

Built on core SQL Server 2008 technologies, the SQL Server 2008 R2 delivers these enhancements by advancing the efficiency to end users on the areas of high availability, enterprise security, enterprise manageability, data warehousing, reporting, scalability, and performance.

SQL Server 2008 R2 new enhancements

SQL Server 2008 R2 meets the large-scale requirements with first-hand enhancements such as two new premium editions and comprehensive additions to existing server editions. The new additions to server and specialized editions of SQL Server 2008 R2 can accommodate the requirement from the lowest level to the highest level of Enterprise needs by offering manageability and straightforward monitoring capabilities.

The installation requirements vary based on the application requirements, and the different editions of SQL Server 2008 R2 which support different features independent to other editions. They offer rich functionality to support mission-critical transactional (OLTP) and Business Intelligence (OLAP) analytical workloads that can be synchronized to access from any type of device. The newest service provision in SQL Server 2008 R2 is SQL Azure, which is a cloud-based relational database service built on SQL Server technologies.

To develop a data management solution to offer performance, scalability, and availability, the selection of SQL Server edition is essential. Though SQL Server 2008 R2 is classified as a marginal change to SQL Server 2008 version, the new editions meet the needs of large-scale data centers and data warehouse deployment. The existing core server edition is coupled with robust and enhanced offerings to enable the highest service levels for mission-critical data loads and provide optimized results. SQL Server editions are classified into three categories: Other, Core, and Premium editions.
