Bill,
If the tables already exist, drop all indexes, FK and PK constraints. They
will
be re-created by the import and this will greatly speed things up.
Try setting an obscenely large SORT_AREA_SIZE before running the import
to speed up index creation. ( Like 50 - 100 meg )
Don't forget to set it back after the import. This is of course requires
bouncing
the database twice.
Use COMMIT=Y and BUFFER=10485760
Buffers larger than 10 meg have not shown a corresponding increase in
speed,
at least in my experience.
HTH,
Jared

Subject: trouble importing
I have a 17Gb db that I need to import (Sun 880 running Solaris 5.8).
the largest tables (of which there are several) are in the 1-3Million row
range . . . a few contain longs. so far it's been running about 24 hours
and is only half-way done.
have 500Mb shared pool and 350Mb db buffer cache - one large rbs (100Mb
extents), COMMIT=N set on import.
any ideas how to speed this up?
thx
