[SQL Snacks Video] Performance Tuning 103 – T-Logs and VLFs


Finally the arrival of Part 3 of my SQL Snack Pack on Performance Tuning! The series is dedicated to help beginners understand how to start performance tuning with SQL Server. The first video was about performing a baseline using the PAL tool.I would highly recommend you review that video as well as my SQL Snack on Instant File Initialization. Also, if you missed part two from yesterday you can review it here.

If you are still interested in learning more about Performance tuning with SQL Server, I will be giving an hour long presentation with the PASS DBA Fundamentals Virtual Chapter on January 6, 2015 (11 am Central Time/Noon Eastern Time).  For more information please visit http://dbafundamentals.sqlpass.org/ and join PASS for a great way to learn more about SQL Server.

[SQL Snacks Video] Performance Tuning 102 – Files, FileGroups, and TempDB

Finally the arrival of Part 2 of my SQL Snack Pack on Performance Tuning! The series is dedicated to help beginners understand how to start performance tuning with SQL Server. The first video was about performing a baseline using the PAL tool.I would highly recommend you review that video as well as my SQL Snack on Instant File Initialization. This second video discusses the importance of properly sizing Data files, placement, and how the Proportional Fill-Algorithm works for data insertion. I’m hoping you get some last minute Performance tuning in before 2015 and so I will be posting the third video within the next 24 hours.

[SQL Snacks Video] Performance Tuning 101 – Baseline with PAL Tools

[SQL Snacks Video] Performance Tuning 101 – Baseline with PAL Tools

Welcome to Part 1 of my SQL Snack Pack on Performance Tuning! The series is dedicated to help beginners understand how to start performance tuning with SQL Server. This first video describes how to setup a baseline for your system using the PAL tools. It is essential to get a baseline before you start performance tuning so that you can determine how effective the efforts done in trying to tune your SQL Server have been.  The PAL tools at first look a little intimidating but they are really very easy to use and extremely helpful for performance analysis. Enjoy and happy baselining!

A special thanks to Edgardo Valdez for showing me the how to use this tool.

SQL Saturday 294 Philadelphia, Nostalgic!

SQL Saturday 294 Philadelphia, Nostalgic!

Less than a week left and I’m extremely excited about SQL Saturday in Philly on June 7th, 2014 and the Precon the day before (I signed up for Allan Hirt’s).  I lived in Philadelphia for about 10 years during which I went to college, had my first two full-time jobs, and my first to kids were born in that area. This SQL Saturday is going to be a blast from the past for me.  The actual event takes place in Malvern PA which is off of 202 in the Northwestern Region of the Philadelphia suburbs.  It is part of the “mainline” and close to Valley Forge, King of Prussia and other historic/tourist attractions.  I used to work in the Mainline area for Johnson Matthey in Wayne (and part time in Malvern) so I’m very excited about taking this trip back to visit friends and family.

For those of you that don’t know about SQL Saturday it is a fantastic event. Here are some of the reasons I’ve encouraged people to attend SQL Saturday events:

I’m speaking at SQL Server Saturday #233 – Washington DC!

I’m speaking at SQL Server Saturday #233 – Washington DC!

It’s that time of the year again when SQL Saturday makes its way back to the Washington DC Area. Here is a link to register and to get all the details you need http://www.sqlsaturday.com/233/eventhome.aspx. I hope to meet a lot of new SQL Server professionals this year. Last year, I met a gentleman that now works with me, so as you can see networking pays off 🙂

Now this year’s SQL Saturday is a little different for me because I will be one of the speakers! I am very excited, as well as a little nervous.  I think having some nervousness helps me prepare because I mentally tell myself “makes sure you know what you are talking about so you don’t look like an idiot!” My topic will be about the fundamentals of Backup and Recovery with SQL Server.  It is targeted towards beginners and here is a brief abstract:

Backup and Recovery are essential parts of and DBA’s job. After all, if you lose your data you lose your job so you need a great backup strategy. In this session we will cover Recovery Models, Backup Types, Backup Strategy, Restores, RTO, RPO, and understanding how your Transaction Log is maintained through backups.

Finally, I wanted to share my thoughts on some of the other interesting sessions that are being held that I will be trying to attend. My disclaimer is that there are so many really great sessions that it is almost impossible to pick sometimes.

Thanks!
Topic:
SQL Server Internals Party: Storage, Memory and the Query Life-cycle

Abstract:
Come meet the Internals of SQL Server at this special get-together! In this presentation we will cover the basics of data storage and querying with SQL Server. We will cover how data is stored in pages and extents and how that translates to data reads/writes with the storage system. Additionally, we will explore how different queries are processed by SQL Server and how the query life cycle works in general. Finally we will cover disk storage and memory and tie it all together. This session is intended to be broad and to give a general overview of how a query is processed in SQL Server and how storage and memory play a part in that. Everyone is invited to this introductory level presentation and should be appealing to DBAs, DB & BI Developers and System Administrators. Party hats not included, rated G for Geeks.

Social Engineering: How to prevent unauthorized access to SQL Server using SQL Logins

Social Engineering: How to prevent unauthorized access to SQL Server using SQL Logins

People are always concerned about Security when it comes to their data.  I don’t blame them, I love keeping my job and I love to protect the sensitive data we store. You also don’t want someone with little SQL skills going in and running huge queries that bring the server to a screeching halt. In all honesty though, security has a HUGE aspect that is outside the realm of anyone’s technical expertise, it’s the “social factor” of security that is tricky.
