Title: IOUGA Live 2001


1
IOUG-A Live! 2001
  • Top Ten Things I Learned at
  • IOUG-A Live! 2001

2
What Is IOUG-A Live?
  • Technical conference?
  • Educational seminars?
  • Time off from work?

3
What is the value in IOUG-A Live?
  • Highly focused technical seminars and lessons
    from experts in the field
  • Broad coverage of the most current issues facing
    Oracle professionals
  • Being out of the office for a week(what do you
    mean the pager doesnt work there?)

4
Top Ten List
  • Here are the top ten things that I learned at
    IOUG-A Live!

5
10 - All Roads Lead to Disney!
  • You cant miss it and you cant get lost
  • The family has something to do while you wallow
    in geekdom.

6
9 - Dancing with EXPLAIN PLAN is easy
  • When you know the steps, that is
  • Many sessions dealt with reading the report that
    EXPLAIN PLAN generates
  • www.elementkjournals.com/dbm/9704/dbm9741.htm
  • www.dbspecialists.com/4dbas/present.html

7
8 - Java Not just lifeblood
  • Several developer sessions and some DBA and data
    warehousing sessions dealt with using Java and
    Java Stored Procedures
  • Oracle is investing much into the Java platform
  • Oracles documentation assumes you are a Java
    guru (I know Im not) and these kinds of sessions
    help.

8
7 - Big Iron Is Coming Back
  • The swing is away from Client/Server and back to
    centralized computing
  • Evidence
  • Oracle 9i Real Application Clusters (Parallel
    Server)
  • PowerUnit Pricing
  • Oracle on mainframes

9
6 - How to save 1 Billion
  • Consolidation
  • Centralized management of software and standards
    to a single set of machines

10
5 - Gas is cheaper in Florida
  • For now.

11
4 - Oracle 9i will do away with DBAs
  • Yeah, right! But it will make being a DBA a bit
    easier
  • Expert systems (if properly configured) will
    handle some of the more mundane tasks
  • DBAs will still need to exist because users will
    still do the unexpected

12
3 - The Big Bash
  • One Part Geek
  • One Part Alcohol
  • One Part Survivor (TM)
  • THE BIG BASH

13
2 - Cache Hit Ratios are for Losers
  • Ratios cant tell you everything
  • Relying on them will cost money
  • The Wait Interface is better
  • vsystem_event, vsession_event, vsession_wait,
    vsesstat
  • These four views allow you to quickly assess the
    performance problem

14
Cache Hit Ratios are for Losers (cont.)
  • Its reliable
  • Its repeatable
  • Its accurate
  • Its effective

15
1 - Real Power of Experience
  • The Power of Real Experience was an apt name
    for the conference
  • Experts were willing to share before, during, and
    after sessions
  • You can learn a lot and have fun doing it.
