Hamid - Are these small tables? Have you considered caching them in memory using Oracle's KEEP pool? This may not be as pertinent to your immediate design as your other questions (like IOT), but it does bear on your question about putting them in a separate tablespace. If you cache them in memory, then it doesn't matter so much where they physically reside. Don Burleson describes the process in some detail in "Oracle High-Performance Tuning using Statspack".
