  1. The Ever Changing & Growing World of Oracle August 2008

  2. Agenda • This is mean to be more of an open discussion • No set time per topic - each topic has just enough info to spur questions and/or open a dialog – so talk • Feel free to ask questions about other topics • No cell phones with ringer turned on (use vibrate) • Email only during breaks under penalty of death • Most of this material represents our customers’ world

  3. Hardware 20th Century Many Choices Yellow?

  4. Hardware 21st Century - Early Many Choices Green?

  5. Hardware 21st Century - Future Single Word: Virtualization

  6. Virtual Private Server

  7. Databases are going virtual too! Regardless of what Oracle says or what platform they push (Xen), VMware (85%) and Hypervisor are/will-be major virtual platforms www.rampant-books.com/book_2008_1_oracle_vmware.htm

  8. What has Happened • Memory • Dirt Cheap (just bought 32GB RAM for my home server for $1300) • Large capacity – my server motherboard can go up to 64GB RAM • CPU • RISC versus CISC no longer an issue • It’s an all 64-bit World – needs to be primary platform (not 32-bit) • Multi-Core CPU’s reign: Cores Threads Total/CPU • AMD Opteron 4 1 4 • Intel Xeon 4 2 8 • Sparc T1 8 4 32 • Sparc T2 8 8 64 • Power 6 2 2 4 • Disk • Disk themselves pretty much the same (i.e. RPM, cache, etc) • Disk architecture highly advanced – really no more “DAS” Cluster to form cheap mainframes

  9. CPU Platform / Features / Limits

  10. What does all this mean for Quest? • Databases Commoditized – we knew this • Software Commoditized – e.g. open source • Hardware Commoditized – cheap & virtualized • Solutions Commoditized (“Virtual Appliances”) • Products: • Need to be cognoscente of virtual environment & focused there • Need to be able to peer within virtualized “black box” components • Looking for “commoditized” answers – i.e. Change X to improve Y • Approach: • Possible that days of software installers are coming to an-end • Throwing hardware at a problem easier & cheaper than tuning • Tuning at the lowest level (SQL) now seen as expensive & timely • Database servers no longer viewed as “islands onto themselves”

  11. Oracle Architecture This is a very streamlined version, there is actually much more these days – but this is enough to build on…

  12. Traditional RAC

  13. Virtual RAC – 50,000 foot view

  14. Virtual RAC – 10,000 foot view

  15. Storage Virtualization too!!!

  16. New Oracle Architecture Diagram Can’t really point to actual hardware for database anymore

  17. Mixed Databases too!!!

  18. Quest Questions • So what do database performance products tell us? • Quest Database Performance Tools • Spotlight for Oracle | MySQL | SQL Server • Spotlight for Oracle RAC • Spotlight for Oracle Xpert (prediction) • Performance Analysis for Oracle | SQL Server • Etc • Our tools monitor and diagnose at the database level • From prior slide though we said … • Need to be cognoscente of virtual environment & focused there • Need to be able to peer within virtualized “black box” components • Looking for “commoditized” answers – i.e. Change X to improve Y • Throwing hardware at a problem easier & cheaper than tuning • Tuning at the lowest level (SQL) now seen as expensive & timely • Database servers no longer viewed as “islands onto themselves” • Foglight if the customer says our tools focus too low

  19. Oracle has Radically Evolved (i.e. Mutated) • The database is almost an operating system itself • ASM replaces Logical Volume Manager and File System • OCFS • OS Files (external tables, 11g Secure Files, BFILE, XMLDB, etc) • Job Scheduler (replacement for older & limited dbms_jobs) • Resource Manager • Oracle also seems to think it’s a true platform vendor • Oracle Enterprise Linux • Oracle VM • OEM for managing non-Oracle software • Oracle Applications (e-business, Seibel, JD Edwards, Peoplesoft) • Oracle Fusion (i.e. middleware layer) • Let’s also remember that Oracle has been on a radical acquisition spree …

  20. Traditional DB Storage

  21. >= 9i Alternatives

  22. LVM vs. ASM 40 Files

  23. Recent Oracle Acquisitons

  24. Don’t forget SQL Developer 

  25. Data Warehousing

  26. DW Load Scenarios

  27. DW Load Approaches

  28. Parallel is KEY !!!

  29. DW Aggregates

  30. Star Schema

  31. SNowflaking

  32. Pre-11g Partitioning Post-11g
