当向定义为数据库管理空间(DMS)的表空间添加新的容器时，或者当扩展现有的容器时，就可能发生表空间数据的重新调整。

When new containers are added to a table space that is defined as database managed space (DMS), or existing containers are extended, a rebalancing of the table space data might occur.

对于数据库管理的表空间，建议拆开lob数据中的常规数据，将LOB数据放在一个很大的表空间中。

It is recommended for database managed tablespaces to split regular data from LOB data, placing LOB data in a large tablespace.

通过数据库管理的空间(DMS)和原始设备，我们可以减少磁盘资源的故障转移时间，因为在故障转移时将不会进行磁盘检查。

With database managed space (DMS) and raw device, we can decrease the time to fail over the disk resources, because there will be no checking of disks during failover.

We transition to actually real world applications later on like a compression-- how do you take a huge amount of data ; and actually whittle it down into something more manageable; something that uses less of your disk space.

然后我们会讲生活中的应用程序,比方说压缩文件——,把大量的数据分解使其更易管理;,并占用尽量少的磁盘空间。
