摘要： Ordered list management is described. An item's position within an ordered list is represented by a path value. A globally unique identifier (GUID) is appended to the path value to enable simultaneous or near-simultaneous modifications to the ordered list without conflict. Furthermore, an ordered list-specific seed value may be prepended to each item's path value to ensure clustering of ordered list items when two or more ordered lists are merged.

摘要： A method and system for selecting a set of systems (nodes) for a server cluster from at least two non-communicating sets of systems. A persistent storage device with cluster configuration information therein is provided as a quorum resource. Using an arbitration process, only one system exclusively reserves the quorum resource. The set with the system therein having the exclusive reservation of the quorum device is selected as the cluster. The arbitration process provides a challenge-defense protocol whereby a system can obtain the reservation of the quorum device when the system that has the reservation fails.

摘要： The present invention includes a method of mirroring memory that reduces the down time for copying information from one physical memory subsystem to a redundant physical memory subsystem by separating the mirroring process into phases. The first phase copies information from the first physical memory subsystem to the redundant physical memory subsystem. During the first phase, applications are not restricted from accessing the first memory subsystem while the first phase of the memory mirroring operation copies the information. The second phase of the memory mirroring operation copies active information to the redundant physical memory subsystem. The active information includes information that was not copied during the first phase and information that changed during the first phase. During the second phase, applications are restricted from accessing the first physical memory subsystem. Because the second phase typically copies a smaller amount of information than the first phase, the down time associated with mirroring the memory is minimal.
摘要翻译：本发明包括一种镜像存储器的方法，其通过将镜像处理分成相位来减少将信息从一个物理存储器子系统复制到冗余物理存储器子系统的停机时间。第一阶段将信息从第一物理存储器子系统复制到冗余物理存储器子系统。在第一阶段期间，应用程序不限制访问第一个内存子系统，而内存镜像操作的第一阶段复制信息。内存镜像操作的第二阶段将活动信息复制到冗余物理内存子系统。活动信息包括在第一阶段期间未被复制的信息和在第一阶段期间改变的信息。在第二阶段期间，应用程序被限制访问第一个物理内存子系统。因为第二阶段通常复制比第一阶段更少的信息量，所以与镜像存储器相关联的停机时间是最小的。

摘要： A technique for performing multiple simultaneous asynchronous input/output operations in a computer operating system. An input/output completion port object is created and associated with a file descriptor. When I/O services are requested on the file descriptor, completion is indicated by a message queued to the I/O completion port. A process requesting I/O services is not notified of completion of the I/O services, but instead checks the I/O completion port's queue to determine the status of its I/O requests. The I/O completion port manages multiple threads and their concurrency.

摘要： A method and system for forming a new cluster of servers having state data that is consistent with the state data of a cluster that previously existed. The previous cluster preserves its state data by recording transactions to a log file in conjunction with a sequence number maintained by each node. The node that recorded the transaction then increments its copy of the sequence number and attempts to replicate the transaction to other nodes of the cluster. If the transaction is replicated, each other node commits the transaction and increments its sequence number. If the node fails before it can replicate the transaction, then no other nodes will increment their sequence numbers, whereby the next logged transaction has the same sequence number as the previously logged, but orphaned replicated transaction. When a new node forms a cluster, it unrolls the log file so as to become consistent with the state of the previous cluster. Logged transactions having duplicate sequence numbers indicate that the first such transaction was not fully replicated. To remain consistent, the first transaction is discarded and not used to update the state of the new cluster.
摘要翻译：一种用于形成具有状态数据的新的服务器集群的方法和系统，该状态数据与先前存在的集群的状态数据一致。先前的集群通过将事务记录到日志文件中并通过每个节点维护的序列号来保留其状态数据。记录事务的节点然后增加其序列号的副本，并尝试将事务复制到集群的其他节点。如果事务被复制，则每个其他节点提交事务并递增它的序列号。如果节点在复制事务之前失败，则其他节点将不会增加其序列号，从而下一个记录的事务与先前记录但是孤立的复制事务具有相同的序列号。当一个新节点形成一个集群时，它会展开该日志文件，以便与上一个集群的状态保持一致。具有重复序列号的记录事务表明第一个此类事务未完全复制。为了保持一致性，第一个事务被丢弃，不用于更新新集群的状态。

摘要： A method and system for communicating modification information to servers in a server cluster. Local changes, such as modifications to a resource requested at one node, are associated into a single transaction. A master node, such as the node that owns the set of resources corresponding to the modifications in the transaction requests permission from a locker node to replicate the transaction. When permission to replicate the transaction is received from the locker node, the master node replicates the transaction by requesting each node in the cluster, one node at a time, to commit the transaction. Any node that does not commit the transaction is removed from the cluster, ensuring consistency of the cluster. Failure conditions of any node or nodes are also handled in a manner that ensures consistency.
摘要翻译：用于将修改信息传送到服务器集群中的服务器的方法和系统。本地更改（例如对在一个节点请求的资源的修改）与单个事务相关联。主节点（例如拥有与事务中的修改相对应的资源集合的节点）从存储器节点请求许可以复制事务。当从更衣室节点接收到复制事务的权限时，主节点通过请求集群中的每个节点（一次一个节点）来提交事务来复制事务。任何未提交事务的节点都将从集群中删除，以确保集群的一致性。任何节点或节点的故障条件也以确保一致性的方式进行处理。

摘要： A method and system for adaptively throttling a computer is provided. Prior CPU utilization is calculated when a CPU enters an idle state. If the prior CPU utilization warrants a change in the CPU performance level, an appropriate CPU performance level is calculated. Policies, including thermal policies and battery charge policies, may be applied to increase or decrease the appropriate CPU performance level. If prior CPU utilization and/or policies dictate a different CPU performance level, the CPU performance level is changed.

摘要： A method and system for transparently failing over a legacy application from a first system to a second system of a server cluster by tracking and checkpointing changes to application configuration information stored in a system's local registry. When an application running on the first system makes a change to the application configuration information in a subtree of the registry, the change is detected and a snapshot of the subtree's data is taken. The snapshot is written to a storage device shared by systems of the cluster, such as a quorum disk. When the application is failed over to a second system, the snapshot for that application is retrieved from the quorum disk and written to the registry of the second system in a corresponding subtree. The application is then run on the second system using the most-recent application configuration information as modified by the other system in the cluster.

摘要： A method and system for transparently failing over a computer name with a legacy application running in a server cluster. When the application is set for failing over in the cluster, the cluster software locates a virtual computer name on which the application is dependent, and associates the virtual name with the application. When the application runs and requests its computer name from the system, the system looks for the virtual computer name, and, if detected, the system returns the virtual computer name to the application as the computer name. The virtual computer name thus moves with the application regardless of the machine on which it is running in the cluster. When the application is not set for failing over in the cluster, the system instead returns the actual machine name.
摘要翻译：一种使用运行在服务器集群中的旧应用程序来透明地将计算机名称故障转移的方法和系统。当应用程序设置为在集群中进行故障转移时，集群软件会找到应用程序所依赖的虚拟计算机名称，并将虚拟名称与应用程序相关联。当应用程序运行并从系统请求其计算机名称时，系统将查找虚拟计算机名称，如果检测到，系统会将虚拟计算机名称作为计算机名称返回给应用程序。因此虚拟计算机名称随着应用程序而移动，而不管其在集群中运行的计算机。当应用程序未设置为在群集中进行故障转移时，系统将返回实际的机器名称。
