    • A client device (701) of a communication system (700) includes, for example, a processor (304) programmed to include a device management tree wherein the processor is operative to receive security policy information (1000), such as that associated with a non-server entity, such as an application on the device, for example, and updates the device management tree with the received security policy information (1002). The device management tree is then accessed in response to a security policy access request, such as from a application or other non server entity during runtime of the wireless client device (1004). As such, not only does the device management tree include external security policy subjects, such as server identities, but different internal security policy subjects are also used to configure a device management tree with suitable security policy enforcement information.
    • 通信系统(700)的客户端设备(701)包括例如被编程为包括设备管理树的处理器(304),其中处理器可操作以接收安全策略信息(1000),诸如与 非服务器实体,例如设备上的应用,并且利用所接收的安全策略信息来更新设备管理树(1002)。 然后响应于诸如来自无线客户端设备的运行时期间的应用或其他非服务器实体的安全策略访问请求来访问设备管理树(1004)。 因此,设备管理树不仅包括诸如服务器身份的外部安全策略对象,而且还使用不同的内部安全策略对象来配置具有合适的安全策略执行信息的设备管理树。

    • A method and apparatus are provided for transferring a resource from the cache of one database server to the cache of another database server without first writing the resource to disk. When a database server (Requestor) desires to modify a resource, the Requestor asks for the current version of the resource. The database server that has the current version (Holder) directly ships the current version to the Requestor. Upon shipping the version, the Holder loses permission to modify the resource, but continues to retain the resource in memory. When the retained version of the resource, or a later version thereof, is written to disk, the Holder can discard the retained version of the resource. Otherwise, the Holder does not discard the retained version. Using this technique, single-server failures are recovered without having to merge the recovery logs of the various database servers that had access to the resource.
    • 提供了一种方法和装置,用于将资源从一个数据库服务器的高速缓存传送到另一个数据库服务器的高速缓存,而无需首先将资源写入磁盘。 当数据库服务器(请求者)希望修改资源时,请求者要求资源的当前版本。 具有当前版本(Holder)的数据库服务器将当前版本直接发送到请求者。 运送版本后,持有人将失去修改资源的权限,但继续将资源保留在内存中。 当将资源的保留版本或其更新版本写入磁盘时,持有者可以丢弃资源的保留版本。 否则,持有人不会丢弃保留的版本。 使用此技术,恢复单服务器故障,而无需合并可访问资源的各种数据库服务器的恢复日志。

    • A method and apparatus for dynamic lock granularity escalation and de-escalation in a computer system is provided. Upon receiving a request for a resource, a scope of a previously granted lock is modified. According to one embodiment, hash lock de-escalation is employed. In hash lock de-escalation, the scope of the previously granted lock held on a set of resources is reduced by de-escalating the previously granted lock from a coarser-grain lock to one or more finer-grain locks on members of the set. According to another embodiment, hash lock escalation is employed. In hash lock escalation, the scope of previously granted locks held on one or more members of the set of resources are released and promoted into a coarser-grain lock that covers the set of resources as well as the requested resource.

    • A method and apparatus for inserting sorted data into an indexed table is provided. Two or more nodes are used to insert the data into the indexed table. Before an entry for each inserted row is stored in the index associated with the table, the key values in the index entry are transformed using an operation that affects the order of the key values. For example, the order of the bytes used to represent the key values in the index entry may be reversed. The index entries are stored in the portion of the index that corresponds to the transformed key values. As a result, the entries for consecutive key values will not necessarily be stored in the same portion of the index. Consequently, the nodes will not have to compete for a "hot" portion of an index if the nodes are inserting data with key values that fall into the same approximate range. The inverse of the transformation operation is performed on the transformed key values read from the index before the key values are supplied to the user.
    • 提供了一种将排序数据插入到索引表中的方法和装置。 使用两个或多个节点将数据插入到索引表中。 在每个插入行的条目存储在与表相关联的索引中之前,索引条目中的键值将使用影响键值顺序的操作进行转换。 例如,用于表示索引条目中的键值的字节的顺序可以颠倒。 索引条目存储在与转换的键值对应的索引部分中。 因此,连续键值的条目不一定存储在索引的相同部分。 因此,如果节点插入具有落入相同近似范围的键值的数据,则节点将不必竞争索引的“热”部分。 在将键值提供给用户之前,对从索引读取的变换的键值执行变换操作的逆。

    • A multi-node video server system in accordance with the invention comprises disk storage associated with a first node which stores at least a portion of a video presentation in the form of plural data blocks, each data block comprising a viewing time segment of the presentation. RAM buffer in a second node receives and stores data blocks of the video presentation from the disk storage in the first node, upon an initial request by a first viewing terminal to view a portion of the video presentation. A communication module in the second node outputs the data blocks, as an isochronous data stream, to requesting terminals. A host controller is coupled to the video server nodes and receives requests from viewing terminals for the video presentation. The host controller causes the communication module in the second node to connect to a viewing terminal which renders the initial request. Additional viewing terminals requesting the same video presentation are also connected to the same communication module if their requests are received within a time period from the initial request that does not exceed a sum of viewing time segments represented by data blocks stored in the RAM buffer. In this manner, both the first requester and subsequent requesting viewing terminals are enabled to receive the audiovisual presentation directly from the same buffer without requiring additional disk accesses for the subsequent viewers. Avoidance of additional internal video server communications is thus achieved.
    • 根据本发明的多节点视频服务器系统包括与第一节点相关联的磁盘存储器,其以多个数据块的形式存储视频呈现的至少一部分,每个数据块包括呈现的观看时段。 在第一节点的初始请求中,第二节点中的RAM缓冲器接收并存储来自第一节点中的磁盘存储器的视频呈现的数据块,以便在第一观看终端初始请求时观看视频呈现的一部分。 第二节点中的通信模块将数据块作为同步数据流输出到请求终端。 主机控制器耦合到视频服务器节点并且从视频终端接收用于视频呈现的请求。 主机控制器使得第二节点中的通信模块连接到呈现初始请求的观看终端。 如果在从不超过存储在RAM缓冲器中的数据块表示的观看时间段的总和的初始请求的时间段内接收到请求相同的视频呈现的附加观看终端也连接到相同的通信模块。 以这种方式,第一请求者和随后的请求查看终端都能够直接从同一缓冲区接收视听呈现,而不需要对后续观看者的附加磁盘访问。 因此实现了避免额外的内部视频服务器通信。
