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). Also, check out my full-week Advanced Oracle Troubleshooting online training at https://blog.tanelpoder.com/seminar

Oracle 11g SQL Plan Management, a.k.a. Baselining, will solve the major issues of change control. We can give you an absolute guarantee - if you configure this as part of your upgrade - that SQL statement execution (performance) will never regress. You may also like our new and free Oracle 12c video tutorials, https://www.skillbuilders.com/free-oracle-database-tutorials .

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 If this information is out of date, performance of queries will suffer.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

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

How To Use The Oracle SQL Net Message To Your Advantage - Introduction
 
01:27
How To Use The SQL*Net Message From Client Event To Your Advantage - webinar introduction. Idle wait events are usually ignored in our performance analysis. It's because they diminish what we should be focus on... most of the time. We need master the "not most of the time" as well. So, in this webinar I'm going to focus on the idle wait event, SQL*Net message from client. I'll show you what this wait event is, why it's important and not important, and how to use it to our advantage in both a time-based analysis and an ASH based analysis. And of course, you'll be able to download and immediately use any tools that I use.

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
