If you are using flashback also, make sure you have enough space to grow
the flashback storage.

Oops, scratch that about the cascading deletes - forgot we're talking
about dropping the table here, not deleting the rows - so that wouldn't
apply.  You would instead need to drop/disable any such constraints
prior to dropping the table, or add the CASCADE CONSTRAINTS clause to
your DROP statement.

Not sure, but I'd think all 3 options would be pretty fast.  Seems that
#3 would be the easiest unless you really want/need to get rid of the
tablespace too.  Just one thing to keep in mind though since you're on
10g - unless you've disabled the recycle bin, with a regular DROP
statement, it won't really be dropped, but rather will just be
moved/renamed into the recycle bin, so you might want to consider adding
the PURGE clause too.  You also might want to check for constraints
first, e.g. cascading deletes.

Brandon
