Oracle Performance Diagnostics and Tuning Seminar with Richard Foote (Perth)

Based in Canberra, Australia, Richard has been working in the local IT industry for over thirty years, twenty plus years with Oracle database technologies. Richard has supported and diagnosed the performance of numerous highly secure, mission-critical, large-scale Oracle database systems. In 2002, he became a member of the world-renowned Oracle OakTable Network and an Oracle ACE Director in 2008. Richard is a very popular speaker and regularly presents at universities, Oracle user group events and conferences including Oracle OpenWorld, IOUG Collaborate, Hotsos Symposium, AUSOUG InSync, ODTUG Kscope, UKOUG Conference and the E4 Enkitec Extreme Exadata Expo. He is especially renowned for his research and knowledge of Oracle indexing structures (and commonly referred to as Mr "Oracle Index"), hosts an internationally acclaimed blog on Oracle Index Internals (https://richardfoote.wordpress.com) and has fully updated and revised this in-depth 2 day seminar on Oracle Indexing Internals which he has presented in over 18 countries.

This is a must attend seminar aimed at Oracle professionals (both DBAs and Developers) who are interested in Performance Tuning.  The seminar will detail how to maximise the performance of both Oracle databases and associated applications and how to diagnose and address any performance issues as quickly and effectively as possible.
When an application suddenly runs “slow” or when people start complaining about the “poor performance” of the database, there’s often some uncertainty in how to most quickly and most accurately determine the “root” cause of any such slowdown and effectively address any associated issues. In this seminar, we explore a Tuning Methodology that helps Oracle professionals to both quickly and reliably determine the actual causes of performance issues and so ensure the effectiveness of any applied resolutions.
Looking at a number of real world scenarios and numerous actual examples and test cases, this seminar will show participants how to confidently and reliably diagnose performance issues. The seminar explores in much detail the various diagnostics tools and reports available in Oracle to assist in determining any database performance issue and importantly WHEN and HOW to effectively use each approach. Additionally, participants are also invited to share their own database/SQL reports where we can apply the principles learnt in diagnosing the performance of their actual databases/applications (we can communicate prior to the event on how to best get any reports of interest).
One of the more common reasons for poor Oracle performance is inefficient or poorly running SQL. This seminar explores in much detail how SQL is executed within the Oracle database, the various issues and related concepts important in understanding why SQL might be inefficient and the many capabilities and features Oracle has in helping to both resolve SQL performance issues and to maintain the stability and reliability of SQL execution.
It’s a fun, but intense, content rich seminar that is suitable for people of all experiences (from beginners to seasoned Oracle experts).
 
Note: Numbers are strictly limited due to the small class nature of the seminars. Please book early to avoid disappointment as seminars are not scheduled regularly.

Section Two: Database Tuning
In Section Two, we explore how to best diagnose any performance issues as quickly as possible to accurately determine any root issue(s) and so apply the most appropriate resolutions. We explore a number of real world examples as well as providing the opportunity to go through any reports participants may wish to share.
As part of determining how to best resolve a number of real world examples, we get the opportunity to explore the internals of the database and the importance of understanding a number of crucial Oracle database concepts (e.g. latch contention, redo log mechanism, RAC cache fusion).
Because of the abundance of Oracle database instrumentation and the wealth of data available in (say) AWR Reports, many Oracle professionals feel swamped and are uncertain how to correctly read these types of reports when trying to diagnose a performance issue. In this section, we look at both WHEN and HOW to read the various reports to very quickly and reliably determine any performance issues and so know with certainty how to apply the most appropriate solution.
We explore the following Oracle supplied database diagnostics methods and when each of them are most appropriate to determine and resolve performance issues using a methodical tuning methodology:
<UL>
<LI>
Statspack Reports
</LI>
<LI>
Automatic Workload Repository (AWR) Reports
</LI>
<LI>
Automatic Database Diagnostic Monitor (ADDM) Reports
</LI>
<LI>
Active Session History (ASH) Reports
</LI>
<LI>
(Advanced) SQL Trace Files

Section Three: SQL Tuning
One of the most common reasons for poor performance is related to poorly running, inefficient SQL statements. In this section we explore in detail a number of important concepts and Oracle capabilities (up to and including Oracle Database 18c) in relation to maximising the performance and stability of SQL statements. Attendees will learn not only how to effectively tune SQL statements, but how to do so in a consistent manner to maximise both SQL performance and stability, by understanding how to determine the root cause of performance issues and hence implement the most appropriate solution to resolve any issues.
