Call a "directory" a "tablespace" and we're on the same page,
aren't we? Actually I'd envision some kind of admin command
"CREATE TABLESPACE foo AS /path/to/wherever". That would make
appropriate system catalog entries and also create a symlink
from ".../data/base/foo" (or some such place) to the target
directory. Then when we make a table in that tablespace,
it's in the right place. Problem solved, no?
It gets a little trickier if you want to be able to split
multi-gig tables across several tablespaces, though, since
you couldn't just append ".N" to the base table path in that
scenario.
I'd be interested to know what sort of facilities Oracle
provides for managing huge tables...
