15 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 32767 (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 ).

16 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 ).

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