Extents in Rollback Segments (20)

原创 IT综合 作者:tsinglee 时间:2007-09-08 16:25:16 0 删除 编辑

Oracle periodically checks the rollback segments of the database to see if they have
grown larger than their optimal size. If a rollback segment is larger than is optimal
(that is, it has too many extents), then Oracle automatically deallocates one or more
extents from the rollback segment.

Oracle定期检查会管段是否增长超过它们的optimal size , 假如超过 , Oracle从回滚段中
自动回收一个或者多个extents.
