Troubleshooting Clusters

Sun, 23 Feb 2014 00:00:00 +0100

Sul canale SQLPASS TV è stata pubblicata la sessione Troubleshooting Clusters tenuta da Allan Hirt (@SQLHA) durante lo scorso PASS Summit 2013.

Abstract

Whether you are new to clusters or have years of experience, you may still cross your fingers when implementing a failover cluster instance (FCI) of SQL Server or an availability group (AG). Both require an underlying Windows Server failover cluster (WSFC), but how many DBAs are involved in the planning and deployment of it? What happens if you try to install an FCI or configure an AG and things don’t work? Or worse, what if the implementation fails after going live in production? This session will cover how to diagnose what went wrong and the free tools available to you, as well as demonstrate how to fix common issues that every DBA should know about.

Skewed Data - Poor Cardinality Estimates... and Plans Gone Bad

Fri, 14 Feb 2014 00:00:00 +0100

Sul canale SQLPASS TV è stata pubblicata la sessione “Skewed Data, Poor Cardinality Estimates, and Plans Gone Bad” tenuta da Kimberly Tripp (@KimberlyLTripp) durante lo scorso PASS Summit 2013.

Abstract

When data distribution is heavily skewed, cardinality estimation (how many rows the query optimizer expects each operator to process) can be wildly incorrect, resulting in poor quality query plans and degraded performance. You’ve probably seen the advice to update all statistics if a query plan looks wrong - but is that the right advice? In many cases, no! These are “sledgehammer” approaches, and while they might solve some problems (usually parameter sniffing problems), they don’t solve the actual problem. In this session, you’ll learn a generalized yet tailored-to-the-table way to solve query plan quality problems for very large tables (VLTs). Topics will include creating, using, and updating filtered statistics; using forced parameterization and templatized plan guides; and understanding stored procedures and how they can leverage filtered statistics.

Building Your T-SQL Tool Kit: Window Function Fundamentals

Sat, 11 Jan 2014 00:00:00 +0100

Sul canale SQLPASS TV è stata pubblicata la sessione Building Your T-SQL Tool Kit: Window Function Fundamentals tenuta da Christina E. Leo (@christinaleo) durante lo scorso PASS Summit 2013.

Abstract

Have you pulled a script to identify duplicates from a blog post but couldn’t quite get it to work because you weren’t sure what that ROW_NUMBER() function was doing? Maybe you heard talk about creating running totals without using subqueries, but you got frustrated when the groups weren’t totaling correctly. Or maybe, you’ve never even heard of window functions. All are good reasons to attend this all-demo session, which demystifies this versatile T-SQL tool. First, we’ll break apart the OVER clause, the key to understanding how window functions work. Then we’ll expand on each group of functions that can use the OVER clause: ranking, aggregate, and analytic functions. Finally, we’ll look at real scenarios where this tool works and talk about performance considerations. When you leave, you’ll have the fundamentals you need to fully develop your mastery of window functions.

Automate Your ETL Infrastructure with SSIS and PowerShell

Fri, 20 Dec 2013 00:00:00 +0100

Sul canale SQLPASS TV è stata pubblicata la sessione Automate Your ETL Infrastructure with SSIS and PowerShell tenuta da Allen White (@SQLRunr) durante lo scorso PASS Summit 2013.

Abstract

Much of your ETL process flow consists of packages that are very similar in structure, capturing data from a single source and transferring that to a single destination. Creating the individual packages can be tedious, and it’s easy to miss something in the process of generating the same basic package over and over again. BI Markup Language makes it easy to build new packages, and PowerShell makes creating the BIML scripts easy. In this session, we’ll see how you can use PowerShell to generate dozens of SSIS packages doing similar tasks from a defined set of ETL sources.

How to Use DMVs to Diagnose Performance Issues

Sat, 23 Nov 2013 00:00:00 +0100

Sul canale PASStv è stata pubblicata la sessione How to Use DMVs to Diagnose Performance Issues tenuta da Glenn Berry durante lo scorso PASS Summit.

Le DMVs (DMV + DMF) forniscono informazioni sullo stato di salute dell’istanza SQL Server. Permettono di diagnosticare problemi di performance e rappresentano uno strumento utilissimo sia per i DBA che per gli sviluppatori; aumentano ad ogni versione di SQL Server e dopo averle toccate con mano non potrete più farne a meno vi consiglio quindi di non perdervi questa sessione!

Tue, 30 Jul 2013 00:00:00 +0200

Sul canale SQLPASS TV, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione Building a Professional Development Plan tenuta da Andy Warren.

Abstract

Ready to take the next step in your career? Ready to build a plan that will get you there? This session will show you a process for building a comprehensive professional development plan - a road map to get to where you want to go! This session is designed to help you build a professional development plan using the same techniques that are used for building business plans. We’ll talk about obtaining and managing resources, setting realistic goals, tracking progress, and what to do when you get off plan. We’re going to look at more than pure technical learning. We’ll discuss how and when to modify your plan to include networking, writing, social engagement, and managing and leadership skills - and talk about the most effective ways to do it. We’ll touch lightly on the value of a mentor and ways to find a good mentor. We will also discuss changing how you look at your career, adopting the mindset of the consultant even if you prefer to retain your status as an employee. It’s not an easy change, but it’s a powerful one, and that is an important component of a professional development plan. At the end of this session you should be ready to spend a day building a plan that will help you move your career forward to a goal that you’ve selected.

Query Tuning Mastery

Thu, 11 Jul 2013 00:00:00 +0200

Sul canale SQLPASS TV, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione “Query Tuning Mastery: Zen and the Art of Workspace Memory” tenuta da Adam Machanic.

Abstract

As SQL Server professionals, we often think of memory in vague, instance-level terms: buffer pool, procedure cache, Virtual Address Space, and so on. But certain tasks require a more in-depth focus, and query tuning is one of them. Large, complex queries need memory in which to work –workspace memory– and understanding the how’s, when’s, and why’s of this memory can help you create queries that run in seconds rather than minutes. This session will teach you how to guide the query processor to grant enough memory for top performance, while also keeping things balanced for the sake of concurrency. You will learn advanced monitoring techniques, expert-level application of specialized query hints, and the memory internals needed to put it all together. If you work with large queries and are serious about achieving scalability and consistently great performance, you owe it to yourself to attend this session.

No More Bad Dates

Sat, 29 Jun 2013 00:00:00 +0200

Sul canale SQLPASS TV, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione No More Bad Dates: Best Practices for Working with Dates and Times tenuta da Kendra Little (Managing Director, Brent Ozar Unlimited).

Abstract

Dates and times seem simple at first. Kendra Little will show you there’s more to it than you think. She’ll give you five best practices that will help you select the right temporal data type, avoid common issues, and use the most effective techniques to aggregate data. She’ll also explain painful problems with query performance and how to avoid them. Choose wisely: the correct types and high performing data access logic will scale like magic.

SQL Server Execution Plans

Sat, 01 Jun 2013 00:00:00 +0200

Sul canale SQLPASS TV, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione SQL Server Execution Plans (From Compilation to Caching to Reuse) tenuta da Maciej Pilecki (SQL Server MVP, MCM).

Abstract

Execution plan reuse is one of the most important aspects of building well-performing and scalable SQL Server solutions. But it’s also the one that is often overlooked during the design phase and becomes very difficult to troubleshoot later. In this session we will discuss in details the following aspects of SQL Server execution plans: compilation, re-compilation, parameterization, caching, reuse and aging. You will leave this session with full understanding of how to improve your server’s performance by increasing execution plan reuse (and how to avoid reuse in case this is necessary).

End-to-End SQL Server PowerPivot

Fri, 08 Mar 2013 00:00:00 +0100

Sul canale SQLPASS TV di YouTube, continua la pubblicazione delle sessioni erogate al PASS Summit 2011. Questa settimana è stata pubblicata la sessione End-to-End SQL Server PowerPivot tenuta Peter Myers (Mentor @ SolidQ).

Abstract

One of the pillars of SQL Server 2008 R2 is Managed Self-Service BI. The SQL Server PowerPivot for Excel add-in is a key offering in this pillar, and delivers an entirely new analytic experience to Excel 2010. The add-in allows analysts to load and prepare large volumes of data from various sources to create a multidimensional model. The model can be enriched with sophisticated calculations. Then the model can then be used as the source for PivotTable and PivotChart reports. And yet that’s not the end of the story. With the SQL Server PowerPivot for SharePoint add-in, the Excel workbooks that host the PowerPivot model can be catalogued in SharePoint and exposed as a data source for other Excel and Reporting Services reports. These SharePoint hosted models can then be managed by IT with scheduled data refreshes from the originating data stores.
