20 Essential Oracle SQL and PL/SQL Tuning Tips
 
01:11:53
SQL and PL/SQL are powerful languages used to access an Oracle database. Today's databases contain mountains of data which presents itself as a challenge when trying to get to the data we want to in a timely fashion. In this FREE Webinar, OCP DBA John Mullins will present 20 valuable tips to help your SQL or PL/SQL perform better. The tips cover every angle regarding SQL and PL/SQL performance, making the presentation suitable for all job roles. Demonstrations will be used to support many of the tips and Oracle 11g and 12c will be covered.

SQL in the City London 2015 - Analyzing SQL Server wait stats
 
29:43
Analyzing SQL Server wait stats, hands-on! Uwe Ricken Waits, as they’re known in the SQL Server world, indicate that a worker thread inside SQL Server is waiting for a resource to become available before it can proceed with executing. They’re often a major source of performance issues. In this session, we’ll walk through an optimal performance troubleshooting process for a variety of scenarios, and illustrate both the strengths and weaknesses of using a waits-only approach to troubleshooting. For more talks, visit http://sqlinthecity.red-gate.com.

Performance Troubleshooting Using Wait Statistics
 
01:43:14
One of the first things you should check when investigating performance issues are wait statistics - as these can often point you in the direction for further analysis. Unfortunately many people misinterpret what SQL Server is telling them and jump to conclusions about how to solve the problem - what is often called 'knee-jerk performance tuning'. In this session, you will learn what waits are, how to analyze them, and potential solutions to common problem patterns. Paul Randal is a Microsoft SQL Server MVP and a Microsoft Regional Director. He spent 9 years working on the SQL Server team, writing DBCC CHECKDB, and ultimately responsible for the entire Storage Engine. In 2007 Paul left Microsoft to co-own and run SQLskills.com, and is a world-renowned author, consultant, and top-rated speaker on SQL Server performance tuning, administration, internals, and HA/DR. When he's not tweeting, blogging, or helping someone recover from a disaster, he's likely to be underwater somewhere in the world with his wife, Kimberly L. Tripp.

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.

Understanding And Resolving Oracle Free Buffer Wait Contention - Seminar Intro
 
06:19
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.

SQL SERVER PART-12: Oracle Linked Database Server
 
03:46
HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO. SQL server 2017 makes it easy to configure linked server. You can use open-query to get or manipulate data of linked server database. CONFIGURATION SUMMARY: PROVIDER : oracle provider for oledb. DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name. e.g. 192.168.1.10:5121/orcl OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ') Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages: • The ability to access data from outside of SQL Server. • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise. • The ability to address diverse data sources similarly. An oracle linked server require OLE DB provider. An OLE DB provider is a DLL that manages and interacts with a specific data source. If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers. An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

Using Skewed Oracle Performance Data To Your Advantage - Seminar Intro
 
07:23
Using Skewed Performance Data To Your Advantage is an important seminar for all DBAs because EVERY Oracle DBA has experienced the effects of skewed performance data, but most don't know how to use that knowledge to their advantage. Have you ever had different groups of users experience different response times from the same exact SQL? Has your IO Admin said the IO response time is fine, but you know single block IOs are taking around 25ms? If you have experienced something like this, then you have likely experienced skewed performance data. I designed this seminar so you will know exactly how to avoid this situation of skewed Oracle wait times and SQL elapsed times. I will teach you how to gather the appropriate data, understand the data and visually demonstrate the situation. This seminar is going to have a deep impact on your Oracle performance work. The skills I teach you will help you devise a sensible solution. Join me for a practical and entertaining journey as we explore the truth about elapsed times and wait events times, turning a potential disaster into your advantage.
