NEOOUG history Get involved and get paid! The San Francisco experience General impressions of recent OOW trips 2012 Oracle conference takeaways 2012 Oak Table World snapshot Hotsos 2013 in Dallas!

Started in 1989 … I first started attending NEOOUG meetings in late 1990’s at the Independence Library Meetings were monthly? Rumpi/Gary/Paul are still around Other area database groups still active include: NEODBUG ( ) ONSSUG ( )

Our first breakout event was in 2003 at LCC with Gaja Vaidyanatha … damagers … compulsive tuning disorder LCC again 2004 with Steven Feuerstein Case Western Reserve days Tom Kyte / Cary Millsap / Jonathan Lewis Crazy Rumpi wanted us to move to 2 day event conferences Cleveland State University and the recent conferences

Chris Date: godfather of relational database theory and design principles. Books include “An Introduction to Database Systems”, “Database in Depth: Relational Theory for Practitioners”. Tom Kyte … Oracle employee and world class speaker. Optional extra cost sessions Monday Dates are Tuesday/Wedneday Working with OOUG ( Columbus based )

Friendly atmosphere and the support of our officers in getting ready to speak Presentations done at work can be recycled/repurposed for NEOOUG ( and vice versa ) An opportunity to grow personally and professionally Mad money for free!

San Francisco experience: PS: the weather is not usually like this!

Oracle Music Festival 2012

Really pushing the engineered systems marketing message Hard to find quality technical sessions but still: Maria Colgan / Tom Kyte / Jonathan Lewis etc 12c Database new features include VARCHAR2 up to (RAW/NVARCHAR2) size greater than 4000 stored out of line like LOB columns. Adaptive execution plans ( build on adaptive cursor sharing and bind variable peeking ). Limited on the fly changes in execution plans at first ( nested loops change to has joins ).

Adaptive statistics … additional statistics including relationships between columns gathered/stored in memory used by optimizer until next instance recycle. Dynamic sampling levels increase to 11and highest level makes dynamic statistics persistent Data optimization or heat maps … database can monitor block usage frequency ( hot/medium/cold ) to help aid resolving access bottlenecks New ILM clause to create/alter table commands allow compression/archival of data after a given periods of time ( might work really well for partitions ).

This is pretty much the atmosphere at Oak Table World … a conference within a conference! Oak Table World 2012 ( at OOW 2012 )
