扩展DB 2服务器涉及将一个或多个成员添加到现有数据共享组中。

Scaling DB2 servers involves just adding one or more members to existing data sharing group.

Sysplex查询并行(一个DB 2数据共享组中的多用户和多任务)是在DB 2 UDB v5中引入的。

CP parallelism (multiple tasks on multiple CPs) was implemented in DB2 V4. Sysplex query parallelism (multiple tasks on multiple members of a DB2 data sharing group) was introduced in DB2 UDB V5.

如果某一个db2子系统停机，或者出于维护的目的暂时离线，那么数据共享组中的其他DB 2子系统就会接管目前离线的数据共享成员的工作负载。

If one DB2 subsystem goes down, or brought off-line for maintenance, other DB2 subsystems in the data sharing group take on the workload of the data sharing member that is now offline.

And the nice thing is that there's a shared behavior there. Just as I can have tuples as an ordered collection of things, strings behave as an ordered collection of things.

共享的行为，就像元组是有序的元素序列,字符串也是有序的元素序列,因此我可以对字符串做同样的操作,我可以把它们连结起来。
