摘要： A coherency manager provides coherent access to shared data by receiving a copy of updated database data from a host computer through RDMA, the copy including updates to a given database data; storing the copy of the updated database data as a valid copy of the given database data in local memory; invalidating local copies of the given database data on other host computers through RDMA; receiving acknowledgements from the other host computers through RDMA that the local copies of the given database data have been invalidated; and sending an acknowledgement of receipt of the copy of the updated database data to the host computer through RDMA. When the coherency manager receives a request for the valid copy of the given database data from a host computer through RDMA, it retrieves the valid copy of the given database data from the local memory and returns the valid copy through RDMA.

摘要： The invention is directed to a caching system for authorization requests. The authorization request is intercepted by a authorization manager. The manager searches in a cache for matching request criteria. If found, the manager returns the result of the request based on the cache information. If not, the normal authorization techniques may be implemented in an associated authorization protocol, whereby the results of the authorization are returned to the requesting party. However, the results of the protocol are also stored in the cache, where they may be found by a later user.

摘要： A method, a system and a computer program product for mapping a client's request to perform boot and/or dump operations to a set of backing files which enable boot and dump operations in a data processing system. A Target Routing Driver (TRD) utility creates multiple Network Installation Management (NIM) objects and/or Network Dump Management (NDM) objects including (1) an Internet Small Computer Systems Interface (iSCSI) boot station and (2) an iSCSI dump collection point. The boot station exports a single iSCSI software (S/W) target from which a set of Diskless Servers obtain a boot image which enables a boot operation. The dump collection point exports a single iSCSI S/W target which is used by Diskless Servers as a dump location. The TRD utility uses the single target (exported from a particular NDM object type) to utilize the minimal resource allocation which allows listening on a single connection. The TRD utility enables block range mapping of the request to the backing files on a remote/separate storage device for the associated Diskless Server.
摘要翻译：一种用于将客户端请求执行引导和/或转储操作映射到一组支持文件的方法，系统和计算机程序产品，这些备份文件使得能够在数据处理系统中启动和转储操作。目标路由驱动程序（TRD）实用程序创建多个网络安装管理（NIM）对象和/或网络转储管理（NDM）对象，包括（1）Internet小型计算机系统接口（iSCSI）引导站和（2）iSCSI转储集合点。引导工具导出单个iSCSI软件（S / W）目标，一组无盘服务器从中获取启动引导操作的引导映像。转储收集点将单个iSCSI S / W目标导出为无磁盘服务器作为转储位置。 TRD实用程序使用单个目标（从特定NDM对象类型导出）来利用允许监听单个连接的最小资源分配。 TRD实用程序可将请求的块范围映射关联到关联的无盘服务器的远程/单独存储设备上的后台文件。

摘要： A method, system, and computer-usable medium for implementing a file directory in a server. An application including a buffer for retrieving and storing at least one entry is interfaced with the file directory. Utilizing a determined average filename length, an estimate of a number of entries among the collection of entries that can be stored by the buffer is determined. In response to determining at least one attribute data field has been requested, the number of entries that can be stored by the buffer is recalculated. Recalculating the number of entries includes determining an amount of data required for storing the collection of filenames, a collection of fixed-length attribute data fields, and a collection of variable-length attribute data fields. The recalculated number of entries is then requested from the file directory, and the buffer is loaded, with the recalculated number of entries.
