问题描述

你好,


您的看法是什么:

最佳类型的临时表空间(AIX 4.3中的DB2V7.2 SP 7 /

多处理器)是DMS ou SMS?


谢谢

最好是DMS,但要确保它足够大。几张最大表的大小不是不合理的。尝试创建

多个容器,每个容器位于不同的磁盘驱动器或不同的磁盘阵列上。


Best is DMS, but make absolutely sure it is plenty large enough. Several
times the size of the largest table is not unreasonable. Try to create
multiple containers, each on different disk drives or different disk arrays.


谢谢


您是否知道临时表空间类型(仅限

tempspace)对性能的影响?

Do you know he impact of the type of temporary tablespaces (only the
tempspace) for the performance ?

数组。


arrays.

你知道他对这种类型的影响吗?性能的临时表空间(只有
tempspace)?

如果你做得对(在不同的驱动器/阵列上有容器)那么你得到

条带化磁盘,以及更好的磁盘子系统吞吐量。单独的磁盘/阵列上的多个容器

也启用了分区内并行性(如果在DB2中设置了某些

parms)。如果您有多个b $ b CPU,那么这种方法效果特别好。


If you do it right (with containers on separate drives/arrays) then you get
striping of disk, and better disk subsystem throughput. Multiple containers
on separate disk/arrays also enables intra-partition parallelism (if certain
parms are set in DB2). This works especially well if you have multiple
CPU''s.
