- Table space can span more than one partition and can have a different page size and buffer pool. 表空间可以跨多个分区,并且可以具有不同的页面大小和缓冲池。
- For online backup, special care needs to be taken for the SYSTEM table space and rollback segments table space. 对于联机备份,需要特别注意SYSTEM表空间和回滚段表空间。
- For table space tracking, a flag for each table space indicates whether a table space is dirty and need to be back up. 对于表空间跟踪,每个表空间的标志指出了表空间是否是脏的,以及是否需要备份。
- The space is comprised of pages, each of which may contain rows from any table defined in the table space. 这种表空间由页构成,每个页可以包含该表空间中定义的任何表中的行。
- If you are working with large data sets, consider using a dedicated buffer pool for the table space. 如果是使用大型数据集,可考虑用专用的缓冲池来代替表空间。
