4. Nash, M. „Oracle 10g: Infrastructure for Grid Computing, Oracle Corporation 2004 That´s what you all know: How it started...

5. However, this definition still remains valid... ... the core of the vision is flexibility — a firm must be able to make its operating costs, and therefore its computing and information costs, totally variable so that they go up and down with business volumes. Quelle: Economist, 15. Januar 2004 in „The next big thing?“ (http://www.economist.com/business/displayStory.cfm?story_id=2352183)

6. ... and implies two “restrictions“ “…a firm must be able…“ • The “Economist” intended Grid addressees are firms  thus, Oracle’s is the “Enterprise”. “…computing and information costs, totally variable...” • “Computing” implies a suitable infrastructure, while “information costs” already focus on an Information Grid.

7. Restrictions? – NO, “compromises” • Strictly following “Foster’s three Point Checklist for a Grid”(*), “no” Grid technology could have been made available to customers. “A Grid Checklist I suggest that the essence of the definitions above can be captured in a simple checklist, according to which a Grid is a system that: • coordinates resources that are not subject to centralized control • using standard, open, general-purpose protocols and interfaces • to deliver nontrivial qualities of service” (*) Ian Foster .: "What is the Grid? A Three Point Checklist“, GridToday, 2002www.gridtoday.com/02/0722/100136.html

8. Oracle Application Server RAC ASM Oracle’s initial (infrastructure) Grid offer:all out of the box or in co-operation with partners Services Application Server Grid Database Grid Storage Grid

9. Oracle ASM ASM Storage Grid Storage virtualization - for example: ASM ASM best practices: http://www.oracle.com/technology/events/oow2005/presentations/ps_s1955_273955_106-1_fin_v1.ppt www.oracle.com/global/de/feedback/massendaten/ORACLE_Effektive_Datenbank_und_Storage-Layouts.pdf www.oracle.com/technology/products/database/asm/index.html

10. RAC Database Grid Server 1 Server 2 Server .. Server n Server n+1 Cache Fusion The Oracle Database Grid is ideally based on RAC More information: http://www.oracle.com/technology/products/database/clustering/index.html

12. Server 2 Server 1 Server Interconnect Host Based Mirroring via ASM for example “RAC on distances“ as an example of adaptiveness • Already from the beginning customers demanded „RAC on distances“ • Main factors to consider: latency and throughput (measured in Mbit) • The latency is limited by the protocol used for the interconnect • Increasing the distance between the nodes, increases the latency (physics) • Use Low Latency protocols on a min. 1 Gbit interconnect • Tune the cluster as good as you can( www.oracle.com/global/de/download/2005_05_04_Horizontale_Skalierbarkeit_ohne_Limit.zip )

13. Database Grid However, database grids are possible without RAC More information: http://www.oracle.com/lang/de/collateral/downloads/ORACLE_White_Paper_Die_Grid_De-Mystifizierung.pdf www.oracle.com/global/de/download/2006_07_12_Grid_beyond_RAC_Markus_Michalewicz.zip

14. The Grid “Evolution” – Oracle takes the steps

15. Services Oracle Application Server Application Server Grid + + + BPEL SOA BAM Infrastructure Service Orchestring Business Monitoring Service Creation Application Server Grid – the trend are „Services“ http://www.oracle.com/technology/tech/webservices/index.html http://www.oracle.com/technology/products/ias/bpel/index.html

16. SOA SOA – the solution? NO – BPEL complements • SOA mainly deals with the interaction of one Web Service with another. It connects former independent services towards a larger purpose (e.g. certain order) • BPEL complements SOA by adding the “orchestring feature” to the general idea of using Web Services. It tries to ensure “to deliver nontrivial qualities of service” as demanded by Foster, and customers (business flows)

17. SOA, BPEL and security – still an issue • Security is still an issue “just” using Web Services • While the access to the data within the Infrastructure Grid • and the data transferred between two services are secured, • one must still rely on the promise of the service provider to use the data only in the way, the service describes • One solution: Only use trivial Web Services or use them in-house.

22. Moderator 28. Juli 200609:15 – 10:00 Markus Michalewicz Date Presentation Oracle´s Grid technology Theme Data availability via RDF –the latest strike: store “knowledge”, not only data • RDF = Resource Description Framework • W3C-Standard • Relationships: Subject  Predicate  Object More Information: www.oracle.com/technology/tech/semantic_technologies

23. :x Presentation :y IF Moderator about theme :x :y THEN has experience in vs. Data availability via RDF –why store data in RDF format? • Main reason: Ontology (representation of knowledge) • Side effects: • permanent changes • various “objects” • permanent enhancements • changes of relationships • Aim: store conclusions via rules

24. Data availability via RDF –utilize the advantages of RDF data • Image search: • “Find me all DICOM images that contain the term ‘JAW’” • Text search: • “Find me all papers that contain the term ‘JAW’” • Map relationships to terms using RDF triples: ‘Mandible’,sameAs’, ‘Jaw’-‘Maxilla’, ‘partOf’, ‘Jaw’

25. Data availability via RDF –utilize the advantages of RDF data – examples • AUDI– Test car configuration • Stanford University – Web Interface
