Rachel,
in case of auto allocate, oracle used 4 or 5 (experts don't even agree on if it is 4 or 5) fixed sizes (64k ...) and based on number of existing extents it will choose when an extent of next size should be allocated. The problem is there is no set formula (or I haven't seen one agreed upon by Oracle ... the answer from Oracle is always fuzzy about this).
That's why, I don't know if the next extent of my table will be 64K or 1M ... if someone knows a formula, I can write a quick script and things would be easy ... but due to lack of formula, everything is a hypothesis ..
In case of dictionary managed, you have next extent size and pct increase and you can predict what the next extent would be. This is also true if you use uniformed extents in LMT. But it isn't easy in LMT and auto allocate. It is probably as predictable as expecting a straight like from a drunken monkey with a crayon.
