    摘要: Reporting on software test coverage, where a set of coverage tasks and a coverage task hierarchy have been established for a software under test (SUT). Establishing a coverage task subset, the subset including at least one coverage task hierarchy element at a level above the lowest coverage task hierarchy level. Identifying when, during a software test, a coverage task in the coverage task subset was completed. Outputting to a user the identity of those portions of the coverage task that have been completed. Refining the coverage task subset in one of the following fashions through the coverage task hierarchy in accordance with user input: depth first progression, breadth first progression.

    摘要: Disclosed is a system, method, and program for limiting input/output (I/O) requests from an application program to a storage device to facilitate the processing of data in memory. A determination is made as to whether an amount of a set of data in memory exceeds at least one threshold. At least one of multiple paths to the storage device is indicated as blocked to I/O requests from the application program. Each indicated blocked path is available for processing the set of data in memory. An I/O request from the application program is received and a determination is made as to whether the received I/O request intends to access the storage device using one indicated blocked path. The I/O request is denied access to the storage device via the blocked path.

    摘要: Control of the discard of data from cache during backup of the data. In a computer-implemented system comprising primary data storage; cache; backup data storage; and at least one processor, the processor is configured to identify data stored in the primary data storage for backup to the backup data storage, where the identified data is placed in the cache in the form of portions of the data, and where the portions of data are to be backed up from the cache to the backup storage. Upon backup of each portion of the identified data from the cache to the backup storage, the processor marks the backed up portion of the identified data for discard from the cache. Thus, the backed up data is discarded from the cache right away, lessening cache pollution.

    摘要: A method, system, and computer program product for managing modified metadata in a storage controller cache pursuant to a recovery action by a processor in communication with a memory device is provided. A count of modified metadata tracks for a storage rank is compared against a predetermined criterion. If the predetermined criterion is met, a storage volume having the storage rank is designated with a metadata invalidation flag to defer metadata invalidation of the modified metadata tracks until after the recovery action is performed.
