如果工作集略微大于池大小,那么在Hypervisor跨lpar重新平衡内存使用量时,会发生一些分页操作。
If the working sets become slightly larger than the pool size, then some paging will occur as the Hypervisor rebalances the memory usage across the LPARs.

Pool interface — a vanilla interface that works as a malloc alternative.
WebSphereApplicationServerfor z/OS 将工作队列机制与线程池组合起来为客户端请求提供服务。
WebSphere Application Server for z/OS combines a work queue mechanism with the thread pool to serve the client requests.
然而,如果为16 GB或16 MB的池分配了足够的内存,那么工作负载就可以在性能方面受益。
However, if an adequate amount of memory has been allocated to the 16-gigabyte or 16-megabyte pool, the workload can benefit in terms of performance.
工作进程用户帐号与应用程序所属应用程序池的用户帐号相同。
Worker process. The account of the worker process is the account set for the application pool that the Web application belongs to.
一个数据库必须至少有一个缓冲池,并且可以有多个缓冲池,这要视工作负载的特征、数据库中使用的数据库页面大小等因素而定。
A database must have at least one buffer pool, and can have a number of buffer pools depending on the workload characteristics, database page sizes used in the database, etc.
一个数据库必须至少有一个缓冲池,并且可以有多个缓冲池,具体要视工作负载的特征、数据库中使用的数据库页面大小等因素而定。
A database must have at least one buffer pool, and can have a number of buffer pools depending on such things as the workload characteristics and database page sizes used in the database.
这种映射能够工作得很好,因为它的确将池大小限制在5 之内,同时又没有将活动实例的数目限制为 5。
The mapping works fine, in that it does limit the pool size to 5, but it doesn't limit that number of active instances to 5.
在我的实验室环境中,必须判断我的工作负载是否适合共享内存池。
In my lab environment, I had to determine if my workload would fit into my Shared memory pool.
您可以使用快照来获得诸如缓冲池命中率、排序堆溢出的次数以及系统工作负载之类的信息。

既然贮存池不再正常工作,一场释放到环境中的放射性灾难就可能发生。
Since the storage pools are not located within containment, a catastrophic radioactivity release to the environment could occur.
如果活动线程的平均数时常接近线程池的最大大小,这说明该线程池太小,不足以满足工作量。
The pool is not large enough to serve the workload, if average number of active threads is constantly close to maximum size of the pool.
因此,应该优化连接池,以便在系统上获得预期的工作量。
Hence, the size of a connection pool should be optimized for the expected workload on the system.
