摘要： A method and mechanism for implementing pipelined prefetching in a computer system is disclosed. Data prefetching is utilized to predictably retrieve information between multiple levels of nodes in the computer system, in which a first server may receive prefetched data from a second server, the second server receives prefetched data from a third server, with the chain of prefetching extending as long as needed/desired to effect efficient data transfers between the nodes.

摘要： A system and method is disclosed that allows resources to be shared among multiple entities, but which can appropriately release system resources after the failure or shutdown of the calling entity. In one approach, a monitoring entity is available to check for session failures. If a session failure is detected, the session is identified in a shared list that is accessible to other related entities. The related entities can be configured to piggyback a message to an appropriate node to kill, shutdown, or release resources associated with the failed session. Alternatively, a related entity can be specifically initiated to send a message to the appropriate node to kill, shutdown, or release the resources.
摘要翻译：公开了一种允许在多个实体之间共享资源的系统和方法，但是可以在主叫实体的故障或关闭之后适当地释放系统资源。在一种方法中，监控实体可用于检查会话故障。如果检测到会话失败，会话在共享列表中被识别，可供其他相关实体访问。可以将相关实体配置为将消息捎带到适当的节点以终止，关闭或释放与故障会话相关联的资源。或者，可以专门启动相关实体来向适当的节点发送消息以杀死，关闭或释放资源。

摘要： A system and method for facilitating a remote procedure call (RPC) using an auto-evolvable RPC interface or record type (an “RPC structure”). Each field of an auto-evolvable RPC structure includes a version number and a default value. During a negotiation process, a client and a server exchange their highest version numbers, thereby indicating their RPC capabilities to each other. A higher or more recent version number may indicate a more recent release of the application comprising the RPC. During an RPC, when the client sends a structure to the server, or vice versa, and it has a more recent version, it may omit one or more fields that are not in the recipient's version. When the server receives a structure from the client, or vice versa, and it has a more recent version, it may populate an extra field (not in the sender's version) with its default value.
摘要翻译：一种使用自动演进的RPC接口或记录类型（“RPC结构”）促进远程过程调用（RPC）的系统和方法。自动演进的RPC结构的每个字段包括版本号和默认值。在协商过程中，客户端和服务器交换其最高版本号，从而向对方显示其RPC功能。更高或更新的版本号可以指示包括RPC的应用的更新版本。在RPC期间，当客户端向服务器发送结构，反之亦然，并且具有更新版本时，可能会省略一个或多个不在收件人版本中的字段。当服务器从客户端收到结构，反之亦然，并且它具有更新版本时，它可能会使用其默认值填充一个额外的字段（不在发件人的版本中）。

摘要： A method and apparatus for efficiently processing data requests in a network oriented n-tier database environment is presented. According to one embodiment of the invention, certain or all data from the tables of a database server device can be maintained in tables on the client device in a client side database cache server system. This local cache allows the network oriented n-tier database system to eliminate the expense of repetitive network transmissions to respond to duplicate queries for the same information. Additionally, the local client device may also keep track of what data is cached on peer network nodes. This allows the client to request that data from a peer database cache server and off load that burden from the database server device. Moreover, the local client may also keep statistics regarding the frequency of requested data in order to optimize the data set maintained in the local database cache server.
摘要翻译：提出了一种在面向网络的n层数据库环境中有效处理数据请求的方法和装置。根据本发明的一个实施例，来自数据库服务器设备的表的某些或所有数据可以在客户机侧数据库高速缓存服务器系统中的客户端设备的表中维护。该本地缓存允许面向网络的n层数据库系统消除重复网络传输的费用，以响应相同信息的重复查询。此外，本地客户端设备还可以跟踪在对等网络节点上高速缓存哪些数据。这允许客户端从对等数据库缓存服务器请求数据，并从数据库服务器设备卸载负担。此外，本地客户端还可以保持关于所请求数据的频率的统计信息，以便优化本地数据库缓存服务器中维护的数据集。

摘要： A session established for an application is suspended from an instance and later resumed on the server or a different server. When a session is suspended, its state is captured and persistently stored as a session image in a data repository, and the session is terminated. When the session is resumed, a new session is established on an instance, the session image of the session to resume is retrieved from the repository and restored to the newly established session. The suspension and resumption of a session may be initiated by an application, which may request the suspension and resumption of a session.
摘要翻译：为应用程序建立的会话从一个实例中暂停，然后在服务器或不同的服务器上恢复。当会话被暂停时，其状态被捕获并持久存储为数据存储库中的会话映像，并且会话终止。当会话恢复时，在一个实例上建立一个新的会话，从存储库中检索要恢复的会话的会话映像并恢复到新建立的会话。暂停和恢复会议可由申请人启动，申请可能要求暂停和恢复会议。

摘要： A structured query may specify attribute values for attributes. An estimate of the number of items that will match the structured query if it is applied to a structured database is determined. If the estimated number of items is below a threshold, the structured query may be relaxed to form new candidate structured queries. The number of candidate queries may be determined based on a desired running time. Each of the candidate structured queries may be determined by changing one or more attribute values of the attributes of the structured query. Estimates of the number of items each of the candidate structured queries will match is determined, and the candidate structured query that has the highest matching estimation is used to query the database. The matching results may be output.
