| sql server 2008 internals and troubleshooting: SQL Server Interview Questions and Answers Vinod Kumar, Pinal Dave, 2021-03 As representatives from the IT community, all of us have had our own experiences of attending interviews - clearing or close to clearing and sometimes with tons of questions and doubts failing miserably. These stories are in the most pleasant or not so pleasant memories of our mind and we will assure you this book will kindle those memories for sure. We have taken tons of interviews and most of the interviews are not revolving around how deep technical and internals you know about the subject - but it revolves around how good you are with the basics.To clear an interview, one doesn't need to know inside-out of a subject, and subjects like SQL Server so vast that every single day we learn something new with this product, and even a complete lifetime will fly off if we keep doing this. Again, the various roles one can get into for products like SQL Server are from Database Developer, Database Modelers, Database Architect, Database Administrator and many more. Hence, this book is geared towards demystifying and a refresher for memories on the fundamentals which sometimes are the most important things to clear any type of interview for any role. Some of the concepts discussed are generic and are not tied to any specific version of SQL Server, but most of it the new features introduced with SQL Server have been included in this book.This book is not a shortcut or a sure to crack interview guide but this book gets you prepared in an organized manner. Let us also assure you this is neither a completely comprehensive guide but surely is a great starter nevertheless. Use this to guide you and be mentally prepared for the big day. When faced with this big day, we get overwhelmed and confused about where to start our preparation. And this book is just that secret recipe in your arsenal to get geared up. Sometimes these basics will help you narrow to a solution quickly when given a scenario.Now this book's flow is Question & Answer mode from start till the end to help you grasp the concepts faster and to the point. Once you get an understanding of concepts, then if we are twisted with the concept in a scenario it becomes easy to solve them. Most companies have a typical way to do interviews which are based on the scenario as per their environment and these are just combinations of the concepts to fit their need and SLA.Though each of these chapters is bucketed for convenience we highly recommend reading each of the sections nevertheless irrespective of the roles you might be doing as each of the sections have some interesting trivia's working with SQL Server. In the industry, the role of accidental DBA's especially with SQL Server is so common. Hence if you have performed the role of DBA for a short stink and want to brush-up your fundamentals then the respective sections will be a great skim. |

| sql server 2008 internals and troubleshooting: Troubleshooting SQL Server Jonathan Kehayias, Ted Krueger, 2011 This book describes, diagnoses, and solves the most common problems with SQL Server 2005, 2008, and 2008 R2. The authors explain a basic approach to troubleshooting and the essential tools. They explore areas in which problems arise with regularity: high disk I/O (RAID misconfiguration, inadequate I/O throughput, poor workload distribution, SAN issues, disk partition misalignment); high CPU usage (insufficient memory, poorly written queries, inadequate indexing, inappropriate configuration option settings); memory mismanagement; missing indexes; blocking (caused mainly by poorly designed databases that lack proper keys and indexing, and applications that apply needlessly restrictive transaction isolation levels); deadlocking (Bookmark Lookup, Serializable Range Scan, Cascading Constraint); full transaction logs (lack of log backups, hefty index maintenance operations, long running transaction, problems with replication and mirroring environments); and accidentally-lost data. Finally, the authors discuss diagnosing tools such as the Performance Monitor, Dynamic Management Views, and server-side tracing. -- |

| sql server 2008 internals and troubleshooting: SQL Server Forensic Analysis Kevvie Fowler, 2009 The tools and techniques investigators need to conduct crucial forensic investigations in SQL Server. The database is the part of a forensic investigation that companies are the most concerned about. This book provides data and tools needed to avoid under or over reporting. Teaches many about aspects about SQL server that are not widely known. A complete tutorial to conducting SQL Server investigations and using that knowledge to confirm, assess, and investigate a digital intrusion. Companies today are in a terrible bind: They must report all possible data security breaches, but they don't always know if, in a given breech, data has been compromised. As a result, most companies are releasing information to the public about every system breech or attempted system breech they know about. This reporting, in turn, whips up public hysteria and makes many companies look bad. Kevvie Fowler's 'SQL Server Forensic Analysis' is an attempt to calm everyone down and focuses on a key, under-documented component of today's forensics investigations. The book will help investigators determine if a breech was attempted, if information on the database server was compromised in any way, and if any rootkits have been installed that can compromise sensitive data in the future. Readers will learn how to prioritize, acquire, and analyze database evidence using forensically sound practices and free industry tools. The final chapter will include a case study that demonstrates all the techniques from the book applied in a walk-through of a real-world investigation. |

| sql server 2008 internals and troubleshooting: Performance Tuning with SQL Server Dynamic Management Views Louis Davidson, Tim Ford, 2010 Dynamic Management Views (DMVs) are a significant and valuable addition to the DBA's troubleshooting armory, laying bare previously unavailable information regarding the under-the-covers activity of your database sessions and transactions. Why, then, aren't all DBAs using them? Why do many DBAs continue to ignore them in favour of tried and trusted tools such as sp_who2, DBCC OPENTRAN, and so on, or make do with the ready made reports built into SSMS? Why do even those that do use the DMVs speak wistfully about good old sysprocesses? There seem to be two main factors at work. Firstly, some DBAs are simply unaware of the depth and breadth of the information that is available from the DMvs, or how it might help them troubleshoot common issues. This book investigates all of the DMVs that are most frequently useful to the DBA in investigating query execution, index usage, session and transaction activity, disk IO, and how SQL Server is using or abusing the operating system. Secondly, the DMVs have a reputation of being difficult to use. In the process of exposing as much useful data as possible, sysprocesses has been de-normalized, and many new views and columns have been added. This fact, coupled with the initially-baffling choices of what columns will be exposed where, has lead to some DBAs to liken querying DMVs to collecting mystic spells. In fact, however, once you start to write your own scripts, you'll see the same tricks, and similar join patterns, being used time and again. As such, a relatively small core set of scripts can be readily adapted to suit any requirement. This book is here to de-mystify the process of collecting the information you need to troubleshoot SQL Server problems. It will highlight the core techniques and patterns that you need to master, and will provide a core set of scripts that you can use and adapt for your own systems, including how to: * Root out the queries that are causing memory or CPU pressure on your system * Investigate caching, and query plan reuse * Identify index usage patterns * Track fragmentation in clustered indexes and heaps * Get full details on blocking and blocked transactions, including the exact commands being executed, and by whom. * Find out where SQL Server is spending time waiting for resources to be released, before proceeding * Monitor usage and growth of tempdb The DMVs don't make existing, built-in, performance tools obsolete. On the contrary, they complement these tools, and offer a flexibility, richness and granularity that are simply not available elsewhere. Furthermore, you don't need to master a new GUI, or a new language in order to use them; it's all done in a language all DBAs know and mostly love: T-SQL. |

| sql server 2008 internals and troubleshooting: Tribal SQL Various, Tony Davis, Jen McCown, 2013-09 What makes you passionate about working with SQL Server? What lessons have you learned, perhaps the hard way, on how to get the best performance and scalability out of your SQL Server databases? We challenged a group of talented, up-and-coming 'new voices' in SQL Server to share their passion and knowledge with the Community. A DBA's core responsibilities are constant. A DBA must maintain and enforce security mechanisms on the data, prepare effectively for disaster recovery, ensure the performance and availability of all the databases in their care. As such, we have chapters providing tips on how to get the most out of features such as data compression, backup verification, performance tuning with traces and extended events, auditing, SSIS, and more. Side by side with these, we have chapters on the importance to a DBA of communicating clearly with their co-workers and business leaders, presenting data as useful information that the business can use to make decisions, adopting a more Agile approach to their work, and sound project management skills. The resulting book, Tribal SQL, is a reflection of how a DBA's core and long-standing responsibilities sit alongside new thinking and fresh ideas about where the DBA role is going, and what it means to be a DBA in today's businesses. |
| sql server 2008 internals and troubleshooting: SQL Server Execution Plans Grant Fritchey, 2012 Every day, out in the various online forums devoted to SQL Server, and on Twitter, the same types of questions come up repeatedly: Why is this query running slowly? Why is SQL Server ignoring my index? Why does this query run quickly sometimes and slowly at others? My response is the same in each case: have you looked at the execution plan? An execution plan describes what's going on behind the scenes when SQL Server executes a query. It shows how the query optimizer joined the data from the various tables defined in the query, which indexes it used, if any, how it performed any aggregations or sorting, and much more. It also estimates the cost of all of these operations, in terms of the relative load placed on the system. Every Database Administrator, developer, report writer, and anyone else who writes T-SQL to access SQL Server data, must understand how to read and interpret execution plans.My book leads you right from the basics of capturing plans, through how to interrupt them in their various forms, graphical or XML, and then how to use the information you find there to diagnose the most common causes of poor query performance, and so optimize your SQL queries, and improve your indexing strategy. |
