If you cannot take the small ones offline, I do not think you can force to use a particular RBS.
You could possible create multiple large RBS then take smaller ones offline then import. After completion put smaller ones online. You can try commit=y to commit after each buffer instead of each object. Use a larger BUFFER size on import to reduce round trips to export file.

Perhaps others have some tricks

Hi all

Can a person somehow force a import process to use a specific rollback segment. I got a live system with many smallish segments, the dump file is about 20 GB and take just over 12 hours to process but it requires a big rollback segment.

I don't want to offline the small once so that only a big one is online since this causes problems with the day to day operation of the client systems.

Ideas.

George
