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

5 ... 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)http://www.economist.com/business/displayStory.cfm?story_id=2352183 However, this definition still remains valid...

6 ... and implies two restrictions …a firm must be able… The Economist intended Grid addressees are firms thus, Oracles 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 Fosters 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, 2002 www.gridtoday.com/02/0722/100136.htmlwww.gridtoday.com/02/0722/100136.html

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

9 Storage virtualization - for example: ASM Storage Grid ASM www.oracle.com/technology/products/database/asm/index.htm l ASM best practices: http://www.oracle.com/technology/even ts/oow2005/presentations/ps_s195 5_273955_106-1_fin_v1.ppt www.oracle.com/global/de/feedbac k/massendaten/ORACLE_Effe ktive_Datenbank_und_Stora ge-Layouts.pdf Oracle ASM

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

11 RAC Instance 1RAC Instance 3RAC Instance 2 ERP CRM ERP Self service Hot Batch Standard Batch Dienste / Services CRS Management System Node 1 ListenerVIPONS operating system Node 3 ListenerVIPONS Node 2 ListenerVIPONS operating system RAC provides Grid concepts out of the box

12 RAC on distances as an example of adaptiveness Host Based Mirroring via ASM for example 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 )www.oracle.com/global/de/download/2005_05_04_Horizontale_Skalierbarkeit_ohne_Limit.zip Server 1 Server 2 Server Interconnect

13 However, database grids are possible without RAC Database Grid 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 Application Server Grid – the trend are Services Infrastructure Service Creation SOABPEL BAM +++ Service Orchestring Business Monitoring http://www.oracle.com/technology/tech/webservices/index.html http://www.oracle.com/technology/products/ias/bpel/index.html Application Server Grid Oracle Application Server Services

16 SOA 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) SOA – the solution? NO – BPEL complements 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.

18 Data availability – still a hard to solve issue Host Based Mirroring via ASM for example Server 1 Server 2 Server Interconnect Replication, Oracle Streams

19 The Grid Evolution – Oracle takes the steps

20 Data availability – a centralized approach: Oracle Clinical Host Based Mirroring via ASM for example Server 1 Server 2 Server Interconnect More information: http://www.oracle.com/industries/life_sciences/clinical.html

21 Data availability – challenges in a distributed environment: Replication, Oracle Streams Find INFORMATION More information: www.oracle.com/database/secure-enterprise-search.html

22 Data availability via RDF – the latest strike: store knowledge, not only data Presentation Oracle´s Grid technology Theme Markus Michalewicz Moderator 28. Juli 2006 09:15 – 10:00 Date RDF = Resource Description Framework W3C-Standard Relationships: Subject Predicate Object More Information: www.oracle.com/technology/ tech/semantic_technologies

23 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 vs. :x Moderator Presentation about theme :y IF THEN :x:y has experience in

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 Stanford University – Web Interface AUDI – Test car configuration
