摘要： A secure naming model for objects in an object-oriented system, wherein names are bound to objects within context objects. The context objects are implemented by name servers, and clients request that a context object "resolve" the name for the object. The name server that implements the context returns a duplicate of the desired object. If a name resolution involves more than one name server, an assurance of security is provided by the first name server to the second name server.

摘要： An extensible set of auxiliary services for objects in an object-oriented system. Every object in an object-oriented system is implemented by an associated object manager. Each object manager in the present invention has an associated object manager identifier that identifies the object manager. Each object manager in the system can optionally provide various auxiliary services for objects that the object manager implements. These auxiliary services are objects implemented by the object manager itself, or by another object manager. For a particular type of auxiliary service, different object managers may provide different auxiliary services. For example, two object managers may provide two different freeze-melt services. For each type of auxiliary service type, there is a well-known context in which auxiliary services of that type are associated with names. For each type of auxiliary service, there is also a well-known function that transforms an object manager identifier into a name. When a client of an object needs to access an auxiliary service for an object, the client first invokes an operation within the object that provides the object manager identifier for the object manager that manages the object. The client then passes the object manager identifier to the well-known function for the desired type of auxiliary service that transforms the object manager identifier into a name. The client resolves the transformed name within a well-known context for the type of auxiliary service desired to obtain a representation of the desired auxiliary service.
摘要翻译：面向对象系统中可扩展的对象辅助服务。面向对象系统中的每个对象都由相关的对象管理器实现。本发明中的每个对象管理器具有标识对象管理器的关联对象管理器标识符。系统中的每个对象管理器可以可选地为对象管理器实现的对象提供各种辅助服务。这些辅助服务是由对象管理器本身或另一个对象管理器实现的对象。对于特定类型的辅助服务，不同的对象管理器可以提供不同的辅助服务。例如，两个对象管理员可以提供两种不同的冷冻融合服务。对于每种类型的辅助服务类型，存在一种众所周知的上下文，其中该类型的辅助服务与名称相关联。对于每种类型的辅助服务，还有一个众所周知的功能，它将对象管理器标识符转换成名称。当对象的客户端需要访问对象的辅助服务时，客户端首先调用对象内的操作，该操作为管理对象的对象管理器提供对象管理器标识符。然后，客户机将对象管理器标识符传递给用于将对象管理器标识符变换成名称的所需类型的辅助服务的公知功能。客户端在知名的上下文中解析变换后的名称以获得期望获得所需辅助服务的表示的辅助服务的类型。

摘要： A method is disclosed for a method to dynamically link a new program image and related library programs into an executable application program image. The method provides for producing a linked list of the required programs by giving the linker an argument representing the designated program image and a naming context which contains data on the associated library programs which are to be linked together. The linker finds all of the required programs, and links them together. The parent maps the program images into the designated addresses thereby completing the linking of the executable application program. In finding the required programs, the linker first checks the image cache to see if the new program and its related library programs is already linked and cached because it was executed before. If the new program is not found in the image cache, the linker object then checks the library program cache to see if the library programs are cached in partially linked form, and will use as many of these as it can find. For any library programs that must still be located, the linker will retrieve them from a data store and will then proceed to link all library programs and the new program image together to form an executable whole. This process of caching new program images with their library programs and caching partially linked library programs individually guarantees a procedure which minimizes the time delay in program start-up when a new program is executed.

摘要： A method and apparatus for client programs adapted for use in an object oriented, distributed computing system, to have the ability to communicate and use references to objects in a way which improves the benefits of software caching are disclosed. A mechanism is described whereby a network object handle (an augmented object handle) can be used to reference both a server and a local cache manager. When the augmented object handle is transmitted it is automatically updated to use a local cache manager in its target environment (i.e. on the same machine on which the receiving client program resides) if possible.

摘要： A method and apparatus are described for a caching file server ("CFS") system which permits end user client programs on a local node of a distributed computer system, to issue requests to read/write data to a remote file and to query/set attributes of the remote file, and to have these requests serviced by the CFS in a way which minimizes the caching resources used as well as minimizes the related network communications. The CFS establishes CFS file programs to interface with the client programs, and sets up a common CFS cache for the file attributes, which cache is kept current via a communications link to a file program in a file server at the remote node containing the file, wherein the file program automatically updates the common CFS cache whenever any attributes change. The CFS also caches the results of bind operations in order to further minimize network calls and redundant cache usage. In addition the CFS coordinates all client program requests for read/write data requests with a virtual memory manager ("VMM") on the local node, servicing all client programs from a single pager program in the VMM which is coupled to a cache program in the file server of the remote node. VMM page-in/page-out operations go directly to the remote file server without CFS intervention. In this manner, network communications and related processing overhead as well as memory resources may be minimized by use of the VMM for caching file data and the Common CFS cache for caching file attributes.
摘要翻译：描述了一种用于缓存文件服务器（“CFS”）系统的方法和装置，该系统允许分布式计算机系统的本地节点上的最终用户客户端程序向远程文件发出读/写数据的请求，并且查询/设置远程文件的属性，以及CFS以这样最小化缓存资源的方式提供这些请求，并使相关的网络通信最小化。 CFS建立CFS文件程序以与客户端程序接口，并为文件属性设置一个通用的CFS缓存，该缓存通过通信链接保存在包含文件的远程节点的文件服务器中的文件程序，其中当任何属性改变时，文件程序自动更新公共CFS缓存。 CFS还缓存绑定操作的结果，以进一步最小化网络呼叫和冗余缓存使用。此外，CFS将所有客户端程序请求与本地节点上的虚拟内存管理器（“VMM”）协调读/写数据请求，从VMM中的单个寻呼程序为所有客户端程序提供服务，该程序耦合到缓存程序远程节点的文件服务器。 VMM页面输入/页面输出操作直接转到远程文件服务器，无需CFS干预。以这种方式，可以通过使用用于缓存文件数据的VMM和用于缓存文件属性的Common CFS缓存来最小化网络通信和相关处理开销以及存储器资源。

摘要： A system and method for resource recovery in a distributed system uses a resource audit service to monitor the status of a client that receives a resource from a service that allocates the resource. The allocating service registers a callback with the resource audit service identifying the client. The resource audit service subsequently monitors the status of the client. When the resource audit service determines that the client has failed, the resource audit service performs the callback to the allocating service indicating the failure of the client. Upon receiving the callback, the allocating service is able to recover the resource from the client.

摘要： A system for recovering resources, wherein the system includes a plurality of allocating services that each allocate resources to clients and a resource audit service in communication with each of the plurality of allocating services. When one of the plurality of allocating services allocates a resource to a client, the one of the plurality of allocating services sends a registration to the resource audit service identifying the client as a recipient of the resource. The resource audit service monitors status of the clients thereby freeing the plurality of allocating services from individually monitoring the status of the clients to which resources have been allocated. When one of the clients fails, the resource audit service sends a failure notification to each of the plurality of allocating services that have allocated a resource to the failed client, thereby allowing each of the plurality of allocating services to recover the resource that had been allocated to the failed client.
