摘要: An apparatus includes a browse mechanism to scan a list of data items. A marker is applied to the data items once they have been scanned by the browse mechanism. The marker provides an indication that a respective data item has been scanned by a given browse entity. The browse mechanism subsequently scans only unmarked data items in the list of data items.

摘要: An apparatus browses a list of data items. The apparatus includes a plurality of browse mechanisms each operable to scan concurrently through a list of data items and a plurality of independent groups each comprising two or more of the plurality of browse mechanisms. The browse mechanisms in a group cooperate together to browse the list of data items such that a data item is seen by only one member of the group.
摘要翻译: 设备浏览数据项列表。 该装置包括多个浏览机制,每个浏览机制可操作以同时扫描数据项列表和多个独立组,每组独立组包括多个浏览机构中的两个或多个。 组中的浏览机制协同工作以浏览数据项的列表,使得只有该组的一个成员看到数据项。

摘要: Provided are methods, data processing systems, recovery components and computer programs for recovering from storage failures affecting data repositories. At least a part of the recovery processing is performed while the data repositories are able to receive new data and to allow retrieval of such new data. Although new data items may be received into the repository and retrieved therefrom during recovery processing, updates to the data repository which were performed before the failure and which are then restored to the repository by the recovery processing are restored within a recovery unit of work and are inaccessible to processes other than the recovery process until successful completion of the recovery unit of work. The recovery processing ensures that the recovered repository is consistent with the state of the repository at the time of the failure, but is available for addition and retrieval of new data items before completion of the recovery processing.
