摘要： An element of a file system is virtually deleted by creating a deletion marker for the element. Two or more separate physical file system directories are presented as one merged (virtual) file system directory to a process running in a silo. The operating system provides the merged view of the file system directories by monitoring file system requests made by processes in silos on a computer or computer system and filtering out those elements associated with deletion markers. Special processing is invoked in response to detecting certain types of file system access requests, including: enumeration, open, create, rename or delete.

摘要： A file disaster recovery system that employs geographical replication of data from a local site to remote site in a such a manner that file requests from clients of the local site can be handled by a file server on the remote site following a failover from the local site to the remote site. Geographical data replication software running on a local server checkpoints to a log in local stable storage all information on file operations that change the file state of the local file system. According to a selected mode, the local geographical data replication software flushes information in the log pertaining to the file operations since the last flush to the remote site. At the remote site, compatible remote geographical data replication software running on a remote file server receives the flushed log and replicates in sequence order the file operations represented in the flushed log. The results of the operations are stored on remote stable storage. The local and remote servers can be clusters or single servers. There is no need for commonality, except for operating and file systems, between the local and remote sites. Because operations are replicated and not low level, formatted data, the local and remote stable file storage can be completely different.
摘要翻译： 文件灾难恢复系统采用从本地站点到远程站点的数据的地理复制，以便从本地站点故障切换后，由远程站点上的文件服务器来处理来自本地站点的客户端的文件请求 到远程站点。 在本地服务器上运行的地理数据复制软件检查点到本地稳定存储的所有信息，文件操作的所有信息都会更改本地文件系统的文件状态。 根据所选择的模式，本地地理数据复制软件刷新自上一次刷新到远程站点后文件操作的日志中的信息。 在远程站点上，在远程文件服务器上运行的兼容的远程地理数据复制软件会接收刷新的日志，并按顺序对刷新日志中表示的文件操作进行复制。 操作结果存储在远程稳定存储上。 本地和远程服务器可以是集群或单个服务器。 除本地和远程站点之间的操作和文件系统外，不需要通用性。 由于操作复制而不是低级别，格式化数据，本地和远程稳定的文件存储可能完全不同。

摘要： The present invention pertains to a system and method for performing remote object invocation. A object-oriented computing system includes a number of independent computing nodes that are interconnected via a communications link. The nodes represent client and/or server computers that do not share memory. Each node includes a number of domains having separate address spaces. Each domain includes one or more threads of execution that invoke one or more objects. The object's method can reside in the same domain as the requesting thread, in a different domain within the same node, or in a different domain in another node. A file descriptor is used to represent those objects whose methods reside in a different domain than the requesting thread. A file descriptor is a protected kernel entity that enables a thread to invoke an object. A thread can only access those objects for which it has received an associated file descriptor. An Object Request Broker (ORB) services the object invocation requests for those objects residing in different domains. The ORB provides a mechanism that translates the file descriptor used to reference an object in one domain into the file descriptor used to invoke the object in the domain having the object's method.
摘要翻译： 本发明涉及用于执行远程对象调用的系统和方法。 面向对象的计算系统包括通过通信链路相互连接的多个独立的计算节点。 节点表示不共享内存的客户端和/或服务器计算机。 每个节点包括多个具有单独地址空间的域。 每个域包括调用一个或多个对象的一个或多个执行线程。 对象的方法可以驻留在与请求线程相同的域中，位于同一节点内的不同域中，或者位于另一个节点中的不同域中。 文件描述符用于表示方法位于与请求线程不同的域中的那些对象。 文件描述符是一个受保护的内核实体，它允许线程调用一个对象。 线程只能访问它已经接收到相关联的文件描述符的那些对象。 对象请求代理（ORB）对驻留在不同域中的对象的对象调用请求提供服务。 ORB提供了一种机制，用于将用于引用一个域中的对象的文件描述符转换为用于调用具有对象方法的域中的对象的文件描述符。

摘要： The present invention pertains to a system and method for tracking object references in an object-oriented computing system including a number of independent computing nodes interconnected by a communications link. The reference counting mechanism tracks references to an object through the use of a messaging protocol. A server node keeps a foreign reference count for each of its objects. The foreign reference count indicates the number of remote nodes having a reference to one of the servers objects. A server node increments the foreign reference count for each object reference that it exports prior to sending it to an intended client node. A client node will send a message to the server node when it has already received the exported object reference and in response to this message, the server node decrements the appropriate foreign reference count. When a client node receives an object reference from another client node, the receiving client node will message the appropriate server node that the receiving client node has a reference to the object. In response, the server node increments the appropriate foreign reference count. The reference counting mechanism utilizes a node failure protocol in order to accurately track the foreign reference counts in light of node failures.

摘要： The present invention provides an elegant and simple way to provide mechanisms for invocation of objects by client applications and for argument passing between client applications and object implementations, without the client application or the operating system knowing the details of how these mechanisms work. Moreover, these mechanisms functions in a distributed computer environment with similar ease and efficiency, where client applications may be on one computer node and object implementations on another. The invention includes a new type of object, termed a "spring object," which includes a method table, a subcontract mechanism and a data structure which represents the subcontract's local private state. This application is directed to a Shared Memory subcontract whereby a client and a server can share a memory region for argument and results passing in certain circumstances without the intervention of the kernel and with no restrictions on the type or complexity of the arguments being exchanged.

摘要： The provisioning of a host computing system by a controller located over a wide area network. The host computing system has power-on code that automatically executes upon powering up, and causes the host to notify the controller of the host address. In a first level of bootstrapping, the controller instructs the host to download a maintenance operating system. The host responds by downloading and installing a maintenance operating system, enabling further bootstrapping. The persistent memory may further have security data, such as a public key, that allows the host computing system to securely identify the source of the download instructions (and subsequent instructions) as originating from the controller. A second level of bootstrapping may accomplish the configuring of the host with a hypervisor and a host agent. A third level of bootstrapping may accomplish the provisioning of virtual machines on the host.

摘要： Two or more separate physical Registry directories are presented as a single (virtual) Registry directory to an application running in a controlled execution environment called a silo. All of the operations normally available to be performed on the Registry directory can be performed on the merge directory, however, the operating system controls the level of access to the keys in the merge directory. The operating system provides the merged view of the Registry directories by a Registry filter driver. The Registry filter model provides a single callback with a notification code indicating the reason the callback was called. The types of notifications which trigger the special processing include: enumeration of a key, enumeration of the value of a key, query a key, close a key, delete a key, create or open a key or rename a key.

摘要： Each virtualized environment on a computer has its own set of firewall rules. The virtualized environments share a single instance of the operating system image, a filter engine and a single network stack. A virtualized environment may be a compartment or a server silo. A virtualized environment is a network isolation mechanism and may be used to prevent use of a computer to traverse network boundaries by creating a separate virtualized environment for each network, enabling a separate set of rules to be applied to each virtualized environment and the network interfaces within it. Virtualized environments may also be used to assign different trust levels to the same physical network. Firewall rules are applied by virtualized environment identifier (ID), enabling separate filters to be applied to each virtualized environment on a computer. A virtualized environment may include or be associated with one or more network interfaces.
