One work around might be to create a dedicated Oracle account with the
suitable rights (INSERT on the table to load) and to use a login trigger
to assign the rollback segment.
Another, and probably much better, way would be to have several sessions
running and parallel (and hopefully assign to different rollback
segments by Oracle). If your volume of data is really big, chances are
that you are loading into a partitioned table. If your input data had
the good taste of being made of several files, each one destined to a
separate partition, would be great. Perhaps some preprocessing is
required. Otherwise split your data file, be certain to have several
free lists to avoid contention, and there you go.
You may have to play with constraints, this is usually the price to pay
to do things in parallel.
