Home -> Community -> Mailing Lists -> Oracle-L -> Re: Specify Rollback for an Export
The only correct resolution to this is to ensure that DML transactions referencing the tables being backed up, are not run at the same time. Bringing the big rollback segment online wont buy you anything. You could delay the inevitable by removing the optimal clauses if set.

Please
respond to
ORACLE-L
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
