Understanding And Resolving Oracle CBC Wait/Latch Contention - Introduction
Understanding And Resolving Oracle CBC Wait/Latch Contention When a server process needs to access a buffer it must access the cache buffer chain (CBC) structure to determine if the buffer is already in the buffer cache. With just the right workload mix, performance can be a problem. Learning about the relevant Oracle internals and how to diagnose and solve CBC performance problems is what this seminar is all about.

Understanding And Resolving Oracle Free Buffer Wait Contention - Seminar Intro
This is the introduction to my video seminar, Understanding And Resolving Oracle Free Buffer Wait Contention. Free buffer waits is one of the most feared of all Oracle wait events. It requires just the right workload mix and configuration to appear. When it does appear, it affects the entire application. As Oracle DBAs, our job is to regain control of the situation and restore application performance. But it is complicated and making the wrong move can make the situation even worse! So, how do you quickly improve performance with a clear understanding of the situation? That's the focus of this seminar. This seminar is designed to take you on a journey. The journey starts with Craig clearly explaining what a free buffer wait is. Then he delves into Oracle's buffer cache, focusing on the least recently used (LRU) lists and the associated algorithms. Craig even role plays as an Oracle foreground process and an Oracle buffer header, locking the details into your brain. Now the details brought together making the cause and effect clear so the presented solutions make perfect sense! Taking it further, two solutions are implemented and the results analyzed. Join Oracle ACE Director Craig Shallahamer as he take you on an unforgettable journey into the Oracle buffer cache zeroing in on understanding and resolving Oracle free buffer waits.

Oracle X$TRACE, Wait Event Internals and Background Process Communication
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).

Oracle: How To Optimize Performance When The Top Event Is DB CPU  - Webinar
In this webinar Oracle Ace, Craig Shallahamer, will demonstrate how to do an Oracle time based analysis including integrating the OS situation into our analysis and finding the true “top” SQL. This journey includes a trip into Oracle’s library cache, memory access control and some interesting ways to improve SQL statement performance. Overall performance sucks as far as the users are concerned. After months of meetings management finally wants you to get involved. You run an AWR report for one of the most intense hours and notice the top “event” is "DB CPU" followed by "cursor: pin S wait on X”. This is where the webinar begins!

OraPub Oracle BloodHound Toolkit - How To Install And Use
In this webinar Craig will demonstrate how to download, install and use his Oracle ASH based BloodHound toolkit. When you need session-level performance analysis data, you need more than ASH data. You need BloodHound because it can do things like multilevel summarization, visualization, working easily with remote data and has the ability to reference any ASH-like formatted data. You can use this webinar as a guide when you install and begin to use the BloodHound toolkit to diagnose Oracle performance problems using ASH data. Craig will start the webinar by downloading the toolkit live. He will end the webinar by using the core reporting tools using AWR ASH data.

How To Use The Oracle SQL Net Message To Your Advantage - Introduction
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.

Inside Tempdb - Bob Ward
Perhaps one of the most frustrating, least understood, and contentious areas (no pun intended) of the SQL Server Engine is tempdb. In this half-day session, we will drive into the internals of the tempdb database. I will warn you up front. This is a 500 level session and will be a very deep internal discussion. It will be very fast-paced with much information to consume. As with past presentations I've done I will be using tools like the Windows Debugger, DMVs, DBCC commands, and possibly even hex editors. I will use as aid in presentation details of memory structures, classes, and bitmaps, Even with the depth of this presentation, I believe anyone will walk away with many practical pieces of knowledge and advice that can help you avoid problems and maximize your usage of tempdb.

Detailing Oracle CPU Consumption: The Missing Link - Seminar Introduction
Detailing Oracle CPU Consumption: The Missing Link helps Oracle Database Administrators answer this question, "What's Oracle doing with all that CPU?" For details go to http://www.orapub.com/video-seminar-detailing-cpu-consumption Here's the problem: While Oracle has the world's most advanced database wait time instrumentation, Oracle does NOT instrument CPU consumption. This presents the Oracle DBA with a tuning handicap because CPU consumption can be a significant component of database time. The unintentional result can be solutions with a wait time bias and solution guessing. In this session you will learn how to determine where Oracle is consuming CPU down to the Oracle kernel code function level and how this relates to the broader performance situation. Now you will be able to more effectively develop solutions to reduce both CPU consumption and wait time. Important: The solution created to solve the CPU detail limitation is Linux based. While I'm confident there are very similar solutions in other operating systems, I do not explore this. What You Will Learn - How to answer the question, "Is that process doing anything or stuck?" - How to answer the question, "So what is Oracle doing with all that CPU?" - How to overcome the problem of understanding limitation when there is little wait time but lots of CPU time. - Finding the Oracle kernel function when there could be a possible bug. - Helping you understand what Oracle is doing, "under the hood." Modules - The problem and what to do about it - My journey to find a solution - Creating the solution based on the Linux "perf" tools - Examples of how to use the tool in production situations For information on how you can watch the whole seminar or for more great eduction from OraPub, go to www.orapub.com

Oracle Database LGWR Three Second Rule. Really?
Go to the blog posting: http://blog.orapub.com/20140608/The-Oracle-Database-LGWR-Three-Second-Rule-Really.html I have learned the part of Oracle Database performance tuning is checking if what you have been taught is actually true. What I'm writing about today has been done before in Oracle Database 10g and 11g, but I wanted to document this using 12c. When I was first learning about the Oracle Database process architecture, the instructor said there are a number of reasons the log writer (LGWR) background process will wake up and do "something." In addition to this, if the LGWR was not signaled to wake up, every three seconds it would wake up by itself and check if there was something it needed to do. Is this "three second rule" really true? That's what this posting is all about.

How to tell if an Oracle parse issue is caused by similar yet unique SQL statements
The video is associated with Craig's 14-Mar-2017 blog post entitled, How Tell If Similar SQL Statements Are Causing Parsing Issues. In Part 1, we knew similar statements was the problem because I was the one subjecting the system with the similar statements! Hopefully no one is doing this in your production system! I will show you three similar SQL problem clues. The first clue is a performance ratio, the second are wait events and the third is creatively using the force matching signature. What are these clues and how do we effectively use them?

Recent Advances in Linux Tracing - Elena Zannoni, Oracle
The many tracing tools available on Linux today provide a wide array of choices for the users. Deciding which of them to use to diagnose system problems on production systems can prove challenging. Various tools have various states of integration within the Linux kernel, and also within different Linux distributions. Bleeding edge features are often just being merged into the upstream Linux kernel. It takes often a long time for such features to be incorporated in commercial distributions. The required set up for the tools and their level of usability also vary significantly. This talk will cover the more popular and actively developed tracing areas focusing on their latest updates and will describe the infrastructure they rely on. An overview of the tracing tools (ftrace, perf, systemtap, DTrace for Linux, etc) will be included with some examples of usage of each. http://events.linuxfoundation.org/
