摘要： In one embodiment, an operating system manages virtualized instances of hardware resources and migration enabled applications partitioned into one of multiple partitions with a separate operating system kernel running in each of the partitions. A migration event controller of the operating system manages the checkpoint and restart process during migration of a virtualized instance of at least one migration enabled application from a departure partition to an arrival partition. The migration event controller supports migration enabled applications to separately specify at least one application specific checkpoint script and restart script to be triggered by checkpoint and restart events by the migration event controller so the at least one migration enabled application can participate in performing the checkpoint and restart process for additional state information during migration of the virtualized instance from the departure partition to the arrival partition.
摘要翻译：在一个实施例中，操作系统管理分配到多个分区中的一个的硬件资源和启用迁移的应用程序的虚拟化实例，其中每个分区中都有单独的操作系统内核。操作系统的迁移事件控制器在将至少一个启用迁移的应用程序的虚拟化实例从出发分区迁移到到达分区期间管理检查点和重新启动过程。迁移事件控制器支持启用迁移的应用程序，以分别指定至少一个特定于应用程序的检查点脚本，并重新启动由检查点触发的脚本，并由迁移事件控制器重新启动事件，以便至少一个启用迁移的应用程序可以参与执行检查点并重新启动在将虚拟化实例从离开分区迁移到到达分区期间的额外状态信息的处理。

摘要： A method, computer program product, and data processing system for efficiently discovering and storing path MTU information in a sending host are disclosed. In a preferred embodiment, two path MTU tables are maintained. One path MTU table contains MTU values corresponding to the first-hop routers associated with the sending host. The other path MTU table contains MTU values corresponding to individual destination hosts. When the sending host needs to send information to a destination, it first consults the MTU table associated with individual destination hosts. If an entry for that destination host is found in the table, the sending host uses that MTU value. If not, the sending host consults the MTU table for the first-hop router on the path to the destination host and uses that MTU value. If that MTU value is too high, a new entry is made in the host-specific MTU table for the destination host.
摘要翻译：公开了一种用于在发送主机中有效发现和存储路径MTU信息的方法，计算机程序产品和数据处理系统。在优选实施例中，保持两个路径MTU表。一个路径MTU表包含与发送主机关联的第一跳路由器对应的MTU值。另一路径MTU表包含对应于各个目标主机的MTU值。当发送主机需要向目的地发送信息时，首先查询与各个目的主机关联的MTU表。如果表中找到该目标主机的条目，则发送主机将使用该MTU值。如果不是，则发送主机在目的地主机的路径上查询第一跳路由器的MTU表，并使用该MTU值。如果该MTU值太高，则在目标主机的主机特定MTU表中创建一个新条目。

摘要： A method, system, and program for monitoring thread usage to dynamically control a thread pool are provided. An application running on the server system invokes a listener thread on a listener socket for receiving client requests at the server system and passing the client requests to one of multiple threads waiting in a thread pool. Additionally, the application sends an ioctl call in blocking mode on the listener thread. A TCP layer within the server system detects the listener thread in blocking mode and monitors a thread count of at least one of a number of incoming requests waiting to be processed and a number of said plurality of threads remaining idle in the thread pool over a sample period. Once the TCP layer detects a thread usage event, the ioctl call is returned indicating the thread usage event with the thread count, such that a number of threads in the thread pool may be dynamically adjusted to handle the thread count.
摘要翻译：提供了一种用于监视线程使用以动态控制线程池的方法，系统和程序。在服务器系统上运行的应用程序调用侦听器套接字上的侦听器线程，以便在服务器系统上接收客户端请求，并将客户端请求传递给等待线程池的多个线程之一。此外，应用程序在侦听器线程上以阻塞模式发送ioctl调用。服务器系统内的TCP层以阻塞模式检测侦听器线程，并且监视等待被处理的多个传入请求中的至少一个的线程计数，并且线程池中的多个线程在一个样本上保持空闲期。一旦TCP层检测到线程使用事件，将返回指示线程计数的线程使用事件的ioctl调用，以使线程池中的线程数可以被动态调整以处理线程计数。

摘要： A method, system and apparatus for improving data transfer rate over a network are provided. When a piece of data is to be transmitted to a target system, it is divided into a number of packets and a determination is made as to whether the number of packets exceeds a threshold number. If so, the packets are transferred in parallel over a plurality of network connections. The ideal network connections are TCP/IP connections. Thus, each packet has an IP header, which contains an IP identification field. An indicium is placed into the IP identification field for proper reconstruction of the data by the target system.

摘要： A system and method to manage device access in a software partition are provided. The illustrative embodiments provide a mechanism for exporting resources/devices from an administrator partition to a software partition in its purview. A trusted device list data structure is provided that identifies which devices are permitted to be exported into a software partition from an administrative partition. This trusted device list data structure also identifies which of the devices in the list of devices should be exported by default when exporting devices to a software partition, i.e. if no overrides are specified. In addition, a user-specifiable mechanism to override the entries in the trusted device list data structure is provided. For security purposes, this mechanism may not be used to export devices not listed in the trusted device list data structure. The mechanism may also be used to prevent the exporting of devices which are exported by default.

摘要： A method, data processing system, and computer usable code are provided for protocol definition for software bridge failover. In a first aspect of the present invention, a first software bridge determines the proper working operation of a physical adapter. Limbo packets are sent to a second software bridge alerting the second software bridge that the first software bridge is no longer bridging traffic responsive to the physical adapter failure in the first software bridge. The second software bridge receives the limbo packets, and, in response to receiving the limbo packets, asserts primary control and initiates bridging of traffic. In an alternative aspect of the present invention a first software bridge sends keep-alive packets. A second software bridge monitors the keep-alive packets from the first software bridge and, in response to a failure to detect the keep-alive packets from the first software bridge, the second software bridge initiates bridging of traffic.

摘要： A method, apparatus, and computer program product in a data processing system for improving response time when clients use network services. If a load level exceeds a load transfer level, the method causes the server to refuse a corresponding percentage of incoming requests received. Then the method sends a message to the requesting client for each refused incoming request, wherein the message requests the requesting client to resend the refused incoming request to a secondary server.

摘要： A method, apparatus, and computer instructions for transferring data in a network data processing system. Data is transferred to a destination in which an address resolution protocol entry is used to transfer this data to the destination. A determination is made as to whether the address resolution protocol entry will expire within a selected threshold while transferring data to the destination. If the address resolution protocol will expire within the selected threshold, the address resolution protocol entry is kept or retained to reduce the interruptions or delays in the transferring of the data.
