Mike, don't you think it would be helpful to show us the import parameters
in use?
If you are doing a conventional import then I would recommend you use a
large buffer= value. If any of the exported options are unnecessary for the
import such as grants then set the associated parameter off for the import:
grants=n. If the target tables exist and ignore=y is in use and some of
these tables are large drop the indexes so they do not have to be maintained
during the table load. Either build them after or let the import rebuild
them.

Subject: Import Question
Hey gang...any suggestions on how to speed up an import?
I am trying to import to a new SAP database server. Oracle 9.2.0.5
on HP-UX11i. There appears to be a lot of I/O activity, but
overall I get a feeling of the system dragging.
Some DB params are:
db_cache_size =3D 2147483648
log_buffer =3D 2097152
sort_area_retained_size =3D 0
sort_area_size =3D 5242880
undo_management =3D AUTO
db_writer_processes =3D 4
java_pool_size =3D 167772160
Any suggestions?
Thanks,
Mike
