    • Controlled partition shut-down is provided within a shared memory partition data processing system including a shared memory partition, a paging service partition, a hypervisor and a shared memory pool within physical memory. The hypervisor manages access to logical pages within the pool and page-out of pages from the pool to external paging storage via the paging service partition. A respective paging service stream exists between the paging service partition and hypervisor for each shared memory partition, with each stream including a stream state. The control method includes: responsive to a shut-down initiating event, notifying the paging service partition to shut down, and determining whether a shared memory partition is currently active, and if so, signaling the hypervisor to complete paging activity for the active memory partition and waiting for its stream state to enter a suspended or a completed state before automatically shutting down the paging service partition.
    • 在共享存储器分区数据处理系统内提供受控的分区关闭,该系统包括物理存储器内的共享存储器分区,寻呼服务分区,管理程序和共享存储器池。 虚拟机管理程序通过寻呼服务分区管理对池内的逻辑页面和从页面到页面的页面的访问到外部分页存储。 在每个共享存储器分区的寻呼服务分区和管理程序之间存在相应的寻呼服务流,每个流包括流状态。 所述控制方法包括:响应关闭启动事件,通知所述寻呼服务分区关闭,以及确定共享存储器分区当前是否处于活动状态,如果是,则指示所述管理程序完成所述活动存储器分区的寻呼活动 并在自动关闭寻呼服务分区之前等待其流状态进入暂停状态或完成状态。
