Susan, you had posted your message to the newsgroup mailing.database.mysql. That is only a mirror of the mailing list [EMAIL PROTECTED], where you should send your postings for them to be readable for all.
InnoDB has a data structure which is equivalent to the 'rollback segment' of Oracle. But, contrary to Oracle, you do not need to configure it in any way. InnoDB uses the rollback segment both to implement transaction rollback and read consistency.
