Hello Viktor Regarding the rollback segments, I heard from Oracle that you need to allocate them with min extents=20. This will cause users to get their own extents and the chance that a new update will overwrite an old update that you need will decrease. Check metalink. they have a paper on this error (if I remember correctly)
