I will have to check your question on 'fewer sorts'.
As far as changes to the SQL statements, there were 1 or 2 sql statements
changed in the application because they no longer worked efficiently with
the change to 8.1.7. But, on the whole (lets say 98%+ of the time) no
changes were made.
Dan;
Everything remained the same on the DB except the version. No changes
made.

It's very simple: don't use rollback segments. Set up your UNDO_TABLESPACE
and let oracle handle it. If you use oracle managed datafiles, oracle will
create as much room as it needs. The parameters that you need to look at

HI All,
My first experience with Oracle was version 4 in a Computer Class in

This is a common misconception.
On startup Oracle determines the number of rollback
