The Price We Pay – Performance and HA with Data Guard
Making database systems highly available is somewhat of a challenge. In the end, a whole chain of middle courses emerges, in which the interests of the end customer must be weighed conscientiously: The manufacturer makes compromises in order to provide the required functions. The planner makes compromises in order to obtain an affordable concept. The implementation makes compromises to make the system operable. And the operation makes compromises in order to survive with it in everyday life.
What does this area of tension look like in concrete terms? Complexity, costs, performance – Oracle ACE Director Martin Klier would like to shed light on these three fields in detail in his presentation, which was developed in close cooperation with Axel vom Stein. The focus will be on the problem area of system performance when using Data Guard: Which disadvantages do I buy by which HA features? How can I orient myself in this labyrinth of compromises with facts?
Making of: The Price We Pay – Performance and HA with Data Guard
Does high availability with Data Guard have a negative impact on the expected performance? Are the tensions between these two important principles of a stable environment important or negligible?
With a corresponding setup, HA expert Axel vom Stein, in cooperation with Martin Klier, got to the bottom of these questions using common performance tools and provides corresponding answers.
This presentation is not so much about the results, but about the way we got to these results. An introduction to Swingbench & ORION as well as preliminary considerations including the necessary evil of using a well-known spreadsheet tool will be included. Of course, everything is true to the motto: Don’t trust any statistics you haven’t faked yourself!
This is the „Making Of“ to Martin Klier’s presentation „The Price We Pay – Performance and HA with Data Guard“ about necessary trade-offs between availability and system performance in the database environment.
OUG Scotland Online Conference – Slide Downloads

Do not run-away! Oracle Performance for the Uncertain
Abstract
It’s eternal. Autonomous Database yes, Self-driving maybe – at the end, one of us has to put boots on the ground if there are shortcomings in real throughput or latency. In the cloud, analysis is a bit harder, on-premises has a few features less. The Oracle RDBMS is changing, but architecture, the way how it works and its limitations are still very similar on all platforms. One dilemma will stay with us: Using precious and finite resources efficiently, while valuable time passes mercilessly.
With this background, I’d like to show you in theory and practice, how Oracle uses resources. How you can analyze with Oracle’s on-board tools what currently is going on, and how you derive from that how to proceed. There is much to influence the runtime behaviour: We’ll talk about Queueing Theory, Wait Events, AWR/Statspack, ASH, Indexes, Statistics, the optimizer, software developers, users and the janitor.
Even runaways are a topic of this entertaining session: They will bite you one day, and you have to be aware!
This talk was made for experienced Administrators and DevOperators, who want to learn more about about performance analysis and its background.

Sharing Experience from 24 Months of Database Upgrade and Migration
Abstract
Sharing Experience from 24 Months of Database Upgrade and Migration Running out of support, security concerns, new features, coming operating system or hardware changes…. there is a long and versatile list of potential reasons for our customers, to change the version of their running Oracle Databases. The „choice“ of situations, challenges and options for changing the version, is at least as long and as versatile as the reasons are. Oracle ACE Director Martin Klier will deliver an unveiled overview about his adventures with logical dependencies, human sensitivities, technical skulduggeries and license traps. All this happens, when one or multiple databases are to be migrated or upgraded to a new version in a controlled fashion. For A as in AIX, L like Linux, S like Solaris, V like Virtualization, W twice in Windows … there was trouble, there was a solution, and there was a new experience!

Danke an die vielen Zuhörer heute im Raum TOKIO des CCN Ost in Nürnberg – es hat mir sehr viel Spaß gemacht!
Zusammenfassung
Es ist ein Dauerbrenner. Self-driving hin, Autonomous Database her; einer von uns muss am Ende eingreifen, wenn es bei der erzielten tatsächlichen Leistung klemmt. In der Cloud analysiert es sich ein bisschen schwerer, On-Premises gibt es ein paar Features weniger. Das Oracle RDBMS wandelt sich, doch die Architektur, Funktionsweise und Beschränkungen des Oracle-Datenbanksystems sind auf allen Plattformen im Alltag noch sehr ähnlich. Was jedoch sicher für sehr lange Zeit gleich bleiben wird, ist ein Dilemma: Endliche Ressourcen in gnadenlos verstreichender Zeit effektiv einzusetzen.
Vor diesem Hintergrund möchte Oracle ACE Director Martin Klier in Theorie und Praxis vorstellen, wie die Ressourcennutzung durch Oracle vor sich geht, wie man mit den Mitteln der Oracle Instanz analysiert was passiert, und wie man davon konkrete Schritte ableitet. Vieles beeinflusst das Laufzeitverhalten: Dazu sprechen wir unter anderem über die Queueing Theorie, Wait Events, AWR/Statspack, ASH, Indexes, Statistiken, den Optimizer, Software-Entwickler, User und den Hausmeister.
Auch Ausreißer sind ein Thema dieser unterhaltsamen Session, gemeint ist jedoch zunächst eine von ostfriesischem Humor geprägte Falschübersetzung: Der Vortrag wendet sich an fortgeschrittene Administratoren und DevOperatoren, die mehr über die Performanceanalyse und deren technologischen Hintergrund in Theorie und Praxis erfahren möchten.

Oracle Magazine Featuring Martin Klier
The Oracle Magazine featured our co-founder, Senior DBA Consultant and Oracle ACE Martin Klier in its „peer-to-peer“ column of the January/February 2016 issue.
Introducing Martin along with two other renowned technicians – Alex Zaballa and Gustavo Gonzalez – the feature was titled „Firsts and Favorites – Three peers who started early, stayed loyal, and stuck to tech basics“. Martin pointed out, how Oracle Core Technologies forms his daily life, and that Oracle Real Application Clusters (Oracle RAC) was his first love in the Oracle world. It’s easy to understand why – RAC is a highly scalable, sophisticated and reliable business continuity and high availability solution. Implemented into the database core, it provides a scale-out capacity that’s still unique in the market, even after so many years of modern RAC architecture.
