How do I edit an Oracle .DMP file, and what changes do i have to make
when exporting from Oracle 8i in Windows 2000 and import into Oracle
9i in Linus AS 2.1

Never edit an export file.  (never say never either, but even though
there are a few things you can change, most editors will mess things
up for you).  You should not have to make any changes.  If there are
any errors you should work through them - For example, a 904 table
does not exist might refer to a system AQ table that no longer exists,
or a table owned by a schema you didn't export.  What you need to
avoid is exporting from a higher version and importing to a lower
version.  There are plenty of other well-known tips, such as do not
use compress=y, and it is better if you create the tablespaces and
tables before the import and use ignore=y.  Google the newsgroups
comp.databases.oracle.* for more info.

Oh yeah, be sure you use binary when you ftp!
