摘要： Use of a smart proxy as a wrapper around a stub in a distributed system. Instead of receiving a stub as a result of a remote procedure call, a caller receives a smart proxy including the stub as an embedded object. The smart proxy performs predefined processing associated with a remote procedure call, the processing possibly occurring before, during, or after a response to the call.

摘要： An improved lookup service is provided that allows for the dynamic addition and deletion of services. This lookup service allows for the addition and deletion of services automatically, without user intervention. As a result, clients of the lookup service may continue using the lookup service and its associated services while the updates occur. Additionally, the lookup service provides a notification mechanism that can be used by clients to receive a notification when the lookup service is updated. By receiving such a notification, clients can avoid attempting to access a service that is no longer available and can make use of new services as soon as they are added to the lookup service.

摘要： Use of a policy object for verification in a distributed system. A machine downloads a policy object containing a reference to code governing verification of data. The machine uses the reference to obtain the code and locally verify data or other information. As particular rules for the data change, the policy object may be updated to provide a reference to the code for the new rules when it is downloaded.

摘要： A system for leasing a group membership in a distributed processing system is provided. In accordance with this system, a remote object requests from an activation group a membership in the activation group for a period of time. Responsive to this request, the activation group determines an appropriate lease period during which time the remote object becomes a member of the activation group and runs in the same address space as other objects of the activation group.

摘要： Downloading code for communicating with a device that joins a network. When the device joins the network, it transmits a multicast packet including a reference to code for use in communicating with the device. Receivers in the network use the reference to download the code for constructing objects to communicate with the device, and the receivers respond with a reference to a lookup service in the network. Using the reference from the receivers, the device registers with the lookup service.

摘要： A system for using a lease to detect a failure and to perform failure recovery is provided. In using this system, a client requests a lease from a server to utilize a resource managed by the server for a period of time. Responsive to the request, the server grants the lease, and the client continually requests renewal of the lease. If the client fails to renew the lease, the server detects that an error has occurred to the client. Similarly, if the server fails to respond to a renew request, the client detects that an error has occurred to the server. As part of the lease establishment, the client and server exchange failure-recovery routines that each invokes if the other experiences a failure.

摘要： A method implemented by a computer-based electronic assistant to receive and manage incoming calls to a subscriber including the steps of receiving an incoming call to the subscriber from a caller; establishing a first connection between the electronic assistant and the caller; establishing a second connection between the electronic assistant and the subscriber; over the second connection, electronically notifying the subscriber of the incoming call; in response to receiving a call accept command from the subscriber over the second connection, linking the caller and the subscriber so that they may communicate with each other; upon linking the subscriber to the caller, switching the electronic assistant to a background mode in which said electronic assistant continues to monitor the subscriber over the second connection while the subscriber is linked with the caller; and in response to receiving a summoning command, switching the electronic assistant into a foreground mode, wherein the electronic assistant when in its background mode responds to a first set of commands including at least the summoning command and when in its foreground mode responds to a second set of commands where the second set of commands is larger than the first set of commands.

摘要： A database system wherein one or more entry databases store a plurality of entries. Each entry is of a given type that defines the fields of the entry. Each field contains or identifies an object with associated attributes or data. The type of each entry may further define behavior in the form of methods the entry can implement. An entry type which is a subtype of another inherits all fields and behavior of its super-type, and contains additional fields and/or defines new/modified behavior. Entries may be expressed in a Java™ programming language. The database system may further employ a search engine which allows queries to be made upon entries in the database. In one implementation, the queries include a read operation, a take operation, and a notify operation. Each query request includes a command indicating the type of operation, and a template which is an entry object having some or all of its fields set to specific values that must be matched exactly. Other fields of the template entry may be specified as wildcards, whose values do not matter. The search engine may further be configured to create an index for caching entries having characteristics which are commonly specified by queries. In one implementation, the databases may also store sets of entries which are matched using sets of templates.
摘要翻译：数据库系统，其中一个或多个条目数据库存储多个条目。每个条目都是给定类型，用于定义条目的字段。每个字段包含或标识具有关联属性或数据的对象。每个条目的类型可以进一步以条目可以实现的方法的形式定义行为。作为另一个子类型的条目类型将继承其超类型的所有字段和行为，并包含其他字段和/或定义新的/已修改的行为。条目可以用Java（TM）编程语言表示。数据库系统还可以采用允许在数据库中的条目进行查询的搜索引擎。在一个实现中，查询包括读操作，执行操作和通知操作。每个查询请求包括指示操作类型的命令，以及作为入口对象的模板，其中的一些或所有字段被设置为必须精确匹配的特定值。模板条目的其他字段可以指定为通配符，其值无关紧要。搜索引擎还可以被配置为创建用于缓存具有由查询通常指定的特征的条目的索引。在一个实现中，数据库还可以存储使用模板集来匹配的条目集合。
