If this cost per active 15-minute user stays flat, but the total CPU line goes up (or down), we can conclude that this is a workload or a capacity related issue.
如果此每15分钟活动用户的成本保持平坦，但总的cpu时间线上升(或下降)，我们就可以断定，这是一个与工作负载或容量相关的问题。
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.
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。
You can change a parameter, a line of code, or a workload item, and rerun your benchmark to get a good measurement of the impact of the change.
您还可以改变参数，某行代码，或者工作负载项，甚至可以重新运行基准测试以获得好的度量结果。
