6. CERN-IT-DB Oracle 9i announcement  Real Application Clusters (Oracle Parallel Server)  “DejaView” – historical query  Performance improvements for Web sites –3 times or $1M  Changes to product bundling –Reduce from ~80 products to Database & Application Server  Virtual Private Databases  See –http://technet.oracle.com/products/oracle9i/http://technet.oracle.com/products/oracle9i/ –http://technet.oracle.com/http://technet.oracle.com/

7. CERN-IT-DB $6M DBA  Ken Jacobs, a DBA barely alive. Beaten into submission by tedious backups and arcane tablespace extensions. Gentleman, we can rebuild him. We have the technology to build the world's first internet-DBA. Better than he was before, better, stronger, faster. Ken Jacobs will be that DBA, Ken Jacobs will be the Six Million Dollar DBA.

8. CERN-IT-DB Parallel Sessions  Many sessions on partitions, Oracle Enterprise Manager, DBA studio, Oracle Internet Directory, Oracle Parallel Server…  Latest advances in Object-Relational features  OCCI – C++ interface to Oracle  Internals of data storage  Replication  Oracle 9i Beta programme  Up to 4 concurrent interesting sessions

9. CERN-IT-DB Partitions  Technique for splitting very large tables / indexes into more manageable units –Partition by: range, list, hash, composite –Unnecessary partitions “pruned” from query by optimiser  64K partitions per table  Each partition can be stored in separate tablespace –In turn mapped to multiple files / filesystems –Tablespaces can be put offline and “exported” –Tablespaces of ~10 x 10GB files gives ~100PB total  Investigating partitions / (transportable) tablespaces for: –Scalability; –Export to regional centres; –Mass Storage Interface

10.  Create and display status of jobs and events  Create and manage administrators  Create and manage groups  Create and display status of jobs and events

11. CERN-IT-DB OEM components: DBA Studio  Central tool for routine DB Admin  DBA Studio combines multiple database tools in one app for managing – Instances, including startup,shutdown, and changing initialization parameters – Schemas, including tables, indexes, and oracle8 objects. – Security, including user accounts, roles, and privileges. – Storage, including tablespaces, datafiles, and rollback segments.

12. CERN-IT-DB OEM Features  DB Grouping  Job scheduling  Notification of events  Routine tasks Schema manager - create, manage schema objects e.g. tables, views, indexes, etc. Security Manager - create, edit users, roles and manage system and object privileges Instance Manager - startup, shutdown database and manage initialization parameters Storage Manager - manage database storage i.e. tablespaces, rollback segments, redo logs, etc. http://technet.oracle.com/products/oem

13. CERN-IT-DB Real Application Cluster (OPS)

14. CERN-IT-DB

15. ORDBMS Advances  Support Object Types and Object References  Support single inheritance (SQL-99) –Can store subtypes in supertype container –Subtypes can override methods of supertype  Type evolution (schema evolution)  (Nested) collections  Extensible indexing, user defined aggregates  Object Types Translator to map to C++

16. CERN-IT-DB OCCI (C++ binding)  C++ version of Oracle Call Interface  Offers both “SQL” access to data… –stmt->executeUpdate(“CREATE TABLE basket (fruit VARCHAR2(30), quantity NUMBER)”);  As well as “ODMG-like” navigational access (modelled after JDBC)  Have access to pre-release of Functional Specification  Access to code as part of Oracle 9i beta

17. CERN-IT-DB Campground  “Fairground” might be a better name… –Your chance to get free squidgy gismos  bags provided –Or discuss with key Oracle developers  Proximity to Oracle HQ meant that many more developers present than otherwise –Essentially entire OCCI / Object teams  Dramatically different to other conferences –Similar value to conference sessions

18. CERN-IT-DB VLDB Discussions  2 nd in a series of meetings with Oracle experts on potential use for handling LHC physics data –Led by Ken Jacobs, VP product strategy –Also performance, data storage, availability & recovery, access methods, replication & distributed DB, objects & extensibility, OCI & C++ development, parallel server groups  Have developed a model for using Oracle –See http://wwwinfo.cern.ch/asd/rd45/workshops/july2000/agenda.htmhttp://wwwinfo.cern.ch/asd/rd45/workshops/july2000/agenda.htm  Have identified key Oracle technologies –partitions, parallel server, enterprise manager, OID, DBA studio, OCCI etc  Testing started for RAW and TAG data –Other data types (ESD, AOD) require Oracle 9i beta (OCCI)  Presentation devoted to this issue will be prepared

19. CERN-IT-DB VLDB Status  Information from conference confirms choice of technologies  Results from RAW & TAG data storage and performance promising –Query performance significantly enhanced using indexes  Potential problems: –Storage overhead for floating point numbers  Floats and Ints currently stored as “Oracle number”  Discussing native support for floats in particular –Mass storage interface  “Solution” using offline partitions being tested –(lack of) machine independent transportable tablespaces  Work-around using Export/Import  Possibility of a tool to convert tablespaces

20. CERN-IT-DB Conclusions  OpenWorld clearly the main Oracle event Direct access to developers in Campground Excellent technical presentations on new features Comprehensive training programme  Few user papers  Too many people  Will be held in San Francisco for next 10 years –2001: Dec 2 – 6 –2002: Nov 17 – 21 –2003: Sep 7 – 11  Mark these dates in your Palm Pilot or Blackberry now ORACLE WORLD OPEN
