option 3 -- increase the rollback segments and redo with users in the
database
jumping in... yes of course an export will use a rollback segment.. to all
intents and purposes, exporting a table is the same as doing a select * from
<tablename> that is written to a spool file.
so it doesn't matter if you are using consistent=y or not (sorry Scott, all
that does is make sure that EVERY table that has referential integrity is
consistent within the constraints). if you are doing an export, and someone
is updating the table, the export will read from the rollback segment
Paul is right, the best way is to export with no users in the system. If you
can't do that (24x7) then change rollback segment number and sizes and pray
each time you run the export. Because you will always be at risk for the
snapshot too old.
