So it does, and the quote is still there in the relevant 10.2 concepts
manual as well. i'd point you at
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96520/parpart.htm#97896instead.
11m is many millions, but I doubt many would consider 2 to be a
valid value for many Gb. It seems to me that a table of 11m rows may benefit
from partitioning to be honest, though i bet it would work better with smart
indexing and more processors with parallelism. Definitely worth a test as
you may just be paying too much for the worng options...
