1 Hotsos Revisited 2013 Datum dinsdag 2 april 2013 Tijd uur Locatie AMIS, Edisonbaan 15 te Nieuwegein Kosten gratis toegang Inschrijven Van 3 t/m 7 maart vindt in Irving, Texas, voor de elfde keer het internationale Oracle Performance Symposium Hotsos plaats. Het symposium belooft dit jaar wederom inhoudelijk hoogstaande presentaties en discussies, want naast presentaties van Tom Kyte, Cary Millsap, Maria Colgan en Steven Feuerstein over performance, staan er onderwerpen op de agenda zoals Big Data, nosql, XML, Statistische toepassingen over performance, Agile (beheer), beheer in de (Oracle) Cloud, Exadata en Oracle 12c. Dit jaar is het vijf Nederlanders gelukt om mee te mogen doen. De heren Toon Koppelaars, Gerwin Hendriksen, Jacco Landlust, Frits Hoogland en Marco Gralike hebben niet alleen het genoegen om ter plekke te zijn, maar geven ook zelf een presentatie over hun favoriete onderwerp. Speciaal voor diegene die niet in Texas kunnen zijn, organiseert AMIS op dinsdagavond 2 april Hotsos Revisited Deze avond kan je de sfeer van Hotsos komen opsnuiven en geven de bovenstaande sprekers nog één keer hun presentatie.

2 Plenaire sessie uur SQL Plan Management Toon Koppelaars This presentation will introduce the audience to the SQL Plan Management (SPM) feature. First, the general concepts and tooling around SPM will be discussed and demonstrated, and the audience will be made aware of a few SPM oddities showing it is not a silver bullet (yet?). The overview of SPM will constitute the majority of the talk. However, at the end, we will also discuss why and how SQL Plan Management was introduced into a large back-office application. Parallelsessie uur Creating Structure in Unstructured Data Marco Gralike The energy and performance drain needed to get something useful out of unstructured data is enormous. Organizations want to do more with all their structured, semi-structured or unstructured data, and when this phenomenon ends up in your database, it will become a serious performance headache. The presentation makes use of the English XML MediaWiki data set (freely available on the internet) and the Oracle 12c database. This data set, on which this presentation demonstrates its findings, contains enormous amounts of those structured, semi-structured and unstructured components, and consists of more than 10+ million free text XML documents. The presentation will show and demonstrate how to get this data, performance-wise, under control via applying logical and physical design principles. Results are shown and discussed, what the effects are if you add partitioning, securefile storage and specificially crafted domain index methods to this performance-draining monster. About Multiblock Reads Frits Hoogland This presentation focuses on multiblock reads, the IO method for full scans for every version of the Oracle database. Whilst being a very old and common IO method, different functionality of this method has silently been introduced with the version 11 of the database. Also new functionality with multiblock reads have been made default behavior and available with version 11 and again with version 11.2

3 Parallelsessie uur "Method GAPP" Used to Mine OEM 12c Repository and AWR Data Gerwin Hendriksen This session will first briefly demonstrate how to use "Method-General Approach Performance Profiling" (Method-GAPP), which was introduced at Hotsos Symposium in 2008, to profile enduser response times and predict performance in multi-tier architectures. Business processes are influenced by many components like web servers, portal servers, Oracle Internet Directory servers, database servers, application servers, etc. The power of "Method-GAPP" is its ability to help you manage environments of arbitrary complexity, regardless of which technologies you've implemented. This session will mainly focus on the value of data inside the OEM 12c repository and the available AWR data. This data is used by the Method, to see what is important for your specific business process response time for the end-user. By using the Method to mine the data, you will be able to find the most involved tiers in your architecture, what the most important SQL is, and what the most involved events are. After creating a model, by the use of "Method-GAPP", the end-user performance can be predicted based on the mined data. The presentation will show results from actual customer experiences in SOA-based systems with more than three nodes. Also a complete case from the most recent "Method-GAPP" white paper will be explained and shown. The session will further show how the Method works and how important relations between available mined data and end-user response times can be found. The session will also show how the results can be used for your optimizations effort. Lessons Learned while Pushing the Limits of SecureFiles Jacco Landlust With the introduction of the new Oracle 11g feature SecureFiles, more and more content will be stored in Oracle databases. Fusion Middleware applications are depending heavily on clobs for their transactional data, also. This session is all about sharing findings on SecureFiles while implementing a WebCenter Content system, that stores 100 million documents (over 35TB) in SecureFiles servicing 65K employees. These findings vary from concurrency, load- to size-related issues. All findings will be dcemonstrated with repeatable test cases.

4 Biografie van de sprekers Marco Gralike Marco Gralike, working for AMIS as a Principal Oracle Database Consultant in the Netherlands, has experience as a DBA since 1994 (Oracle 6). Marco is also eager and skillful in other fields, like Operating System Administration and Application Servers, mainly in finding working, performing solutions. Marco has been specializing in Oracle XMLDB, since 2003, focusing on his old love, database administration and performance. He is an Oracle XMLDB enthusiast.
