Well then forget the compress issue. I can shutdown the
database, move the db files to another directory, do the
usual dba excercises to let Oracle know the new location,
and startup with no problems. (Oracle 7.3 on Netware3)
The reason I remember is that when we upgraded from 7.0 to
7.3, the documentation about placement of db files was
incredibly sucky. Naturally, I researched it throughly
(various TARs, complaints, etc.), and it turns out it was
much simpler than the docs made it sound.
Anyways, I'll submit an iTar since I need to know this stuff
when we migrate to NT/Win2k in the near future.
