Statistics in Oracle and SQL Server
 
01:28:28
The better the information that Oracle and SQL Server have about the data in a database, the better choices they can make on how to execute the SQL. Statistics are Oracle's and SQL Server's chief source of information. If this information is out of date, performance of queries will suffer. In their third live 'Oracle vs. SQL Server' discussion, Jonathan Lewis (Oracle Ace Director, OakTable Network) and Grant Fritchey (Microsoft SQL Server MVP) will look at statistics in Oracle and SQL Server. Do Oracle and SQL Server gather the same information? What does each optimizer use this information for? And how can Oracle and SQL Server administrators override the defaults for better (or worse) performance? These are just some of the questions that Jonathan and Grant will try to answer in another not-to-be-missed session. As before, this will be a live discussion with limited supporting slides, and will conclude with a Q+A session with Jonathan and Grant. Be prepared for a lively exchange that will not only entertain, but will teach you key concepts on Oracle and SQL Server. For our complete archive please go to http://www.red-gate.com/oracle-webinars

Oracle X$TRACE, Wait Event Internals and Background Process Communication
 
01:48:41
In this session we will look into some internals of Oracle background process communication and also some special types of wait events that most people aren’t aware of. We will use some exotic tracing for internals research and fun and some of this stuff is actually useful in real life too! I’m not going to reveal everything upfront, as this is a secret internals hacking session after all ;-) We will use various techniques to research what the “reliable message” wait event is about and how reliable background process communication is orchestrated in Oracle. This is a hacking session, not formal structured training, so I’ll just do free form demos and talk (probably no slides, just hacking stuff on the command line).

How to Gather SQL Resource Consumption Metrics in Oracle
 
01:20:51
Presented by Karen Morton Tues 8th May 2012 Summary SQL is utilized to return data via our applications to service user requests. Whether it's a single customer lookup or a huge month end summary report, the SQL we write must gather the correct data and return it to the user. Ensuring that the SQL you write can do this in a timely and efficient manner, both now and in the future, requires that you measure and evaluate what resources your query must use. In this webinar, we'll cover several methods for how to collect data that show you precisely how your SQL consumes resources: Using AUTOTRACE Using DBMS_XPLAN.DISPLAY_CURSOR Using Report SQL Monitor Using ASH (Active Session History) and AWR (Automatic Workload Repository) data You'll learn how to utilize the data to understand the work your SQL is doing and the resources it consumes; identify currently evident performance issues as well as areas that could be problematic in the future; and modify your SQL to use less resources more efficiently while still returning the desired results. A live Q+A session with Karen Morton follows the presentation. For our complete archive, and to sign up for upcoming webinars please go to http://www.red-gate.com/oracle-webinars

Identifying Long Running Queries
 
01:10:08
Tuning the performance of your queries in SQL Server can be a lot of work. However, in order for your systems to receive the full benefits of query tuning, you must tune the queries that need it the most. This session will show you three different methods for determining which of the queries on your system are being called the most frequently, take the longest period of time to run, or are using the most resources. You'll be able to use the information in this session to quickly set up your own metrics gathering processes in order to understand what is happening on your systems and which queries will benefit most from tuning. Grant Fritchey is a SQL Server MVP with over 20 years’ experience in IT including time spent in support and development. Grant has worked with SQL Server since version 6.0 back in 1995. He has developed in VB, VB.Net, C# and Java. Grant has authored books for Apress and Simple-Talk, and joined Red Gate as a Product Evangelist in January 2011.

How an intense and diverse SQL statement workload can cause Oracle parsing problems
 
09:19
Make your library cache angry! This video is about how an intense and diverse SQL statement workload can cause Oracle parsing problems. There are many reasons for Oracle parsing related performance issues and many ways to identify them. So, I am narrowing the scope by focusing on one possible cause, that is, an intense and diverse SQL statement workload. I will use Oracle's wait interface to identify the root cause. Sound dry and boring? To make this a little more interesting and a whole lot more fun, I'm going to approach this from a non-traditional, almost backward perspective. After explaining some of the Oracle internals, I'm going to create a parsing intensive workload and then watch what happens... in real time. The educational impact is so powerful, I recorded a video This is video is part of Craig's blog post: http://blog.orapub.com/20170126/how-an-intense-and-diverse-sql-workload-causes-oracle-parsing-problems.html For more information go to www.orapub.com

Setting up the Debugger in SSMS : If you have connected to SQL Server using (local) or . (period), and when you start the debugger you will get the following error Unable to start T-SQL Debugging. Could not connect to computer. To fix this error, use the computer name to connect to the SQL Server instead of using (local) or . For the examples in this video we will be using the following stored procedure. Create procedure spPrintEvenNumbers @Target int as Begin Declare @StartNumber int Set @StartNumber = 1 while(@StartNumber [ @Target) Begin If(@StartNumber%2 = 0) Begin Print @StartNumber End Set @StartNumber = @StartNumber + 1 End Print 'Finished printing even numbers till ' + RTRIM(@Target) End Connect to SQL Server using your computer name, and then execute the above code to create the stored procedure. At this point, open a New Query window. Copy and paste the following T-SQL code to execute the stored procedure. DECLARE @TargetNumber INT SET @TargetNumber = 10 EXECUTE spPrintEvenNumbers @TargetNumber Print 'Done' Starting the Debugger in SSMS : There are 2 ways to start the debugger 1. In SSMS, click on the Debug Menu and select Start Debugging 2. Use the keyboard shortcut ALT + F5 At this point you should have the debugger running. The line that is about to be executed is marked with an yellow arrow Step Over, Step into and Step Out in SSMS : You can find the keyboard shortcuts in the Debug menu in SSMS. Let us understand what Step Over, Step into and Step Out does when debugging the following piece of code 1. There is no difference when you STEP INTO (F11) or STEP OVER (F10) the code on LINE 2 2. On LINE 3, we are calling a Stored Procedure. On this statement if we press F10 (STEP OVER), it won't give us the opportunity to debug the stored procedure code. To be able to debug the stored procedure code you will have to STEP INTO it by pressing F11. 3. If the debugger is in the stored procedure, and you don't want to debug line by line with in that stored procedure, you can STEP OUT of it by pressing SHIFT + F11. When you do this, the debugger completes the execution of the stored procedure and waits on the next line in the main query, i.e on LINE 4 in this example.

By clicking on the grey margin on the left hand side in SSMS (to remove click again) 2. By pressing F9 (to remove press F9 again) Enable, Disable or Delete all breakpoints : There are 2 ways to Enable, Disable or Delete all breakpoints 1. From the Debug menu 2. From the Breakpoints window. To view Breakpoints window select Debug =] Windows =] Breakpoints or use the keyboard shortcut ALT + CTRL + B Conditional Breakpoint : Conditional Breakpoints are hit only when the specified condition is met. These are extremely useful when you have some kind of a loop and you want to break, only when the loop variable has a specific value (For example loop varible = 100). How to set a conditional break point in SSMS : 1. Right click on the Breakpoint and select Condition from the context menu 2. In the Breakpoint window specify the condition Text version of the video http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures.html Slides http://csharp-video-tutorials.blogspot.com/2015/09/debugging-sql-server-stored-procedures_28.html
