I'm not sure whether there is another way, but can the following be done?

in the after logon trigger specify: 'SET TRANSACTION USE ROLLBACK
SEGMENT..."?

don't know whether this statement is allowed inside a trigger and also
whether it will work.

and also, export commits periodically, the statement will go off after the
first commit(even if it was allowed)

I am performing an export of a set of very large tables. I am not using
CONSISTENT mode. The exports are failing due to snapshot too old errors. The
application uses many small rollback segments, but has one large one for big
transactions. Is it possible to force the export to use the large segment
without taking all the others (except System) offline? I have seen this
question asked on the list before, but did not find a definitive follow-up
answer. 

Thanks
Erik
