Guy,
The 'drop tablespace' command does a number of items. It purges the
data
dictionary of all references to that tablespace, removes the file
information
from the control file, closes the datafile(s) and releases them back to
the
operating system. All that being said, if you then want to reuse the
datafile
as a new tablespace then you have to wipe it. The simplest reason being
that
you may be using it in a database with a different block size. Look at
it this
way, if you were starting to write a new book, would you use a notepad
of erased
paper? If you did there might end up being some very interesting side
notes
running around.
