摘要： Provided are a method, system, and program for destaging a track from cache to a storage device. The destaged track is retained in the cache. Verification is made of whether the storage device successfully completed writing data. Indication is made of destaged tracks eligible for removal from the cache that were destaged before the storage device is verified in response to verifying that the storage device is successfully completing the writing of data.

摘要： Provided are a method, system, and program for establishing a point-in-time copy. A source relationship data structure and target relationship data structure are generated when establishing a point-in-time copy relationship between source and target storage areas, wherein the source and target relationship data structures each include an indicator for each source storage area and corresponding target storage area in the point-in-time copy relationship. The source and target relationship data structures are initialized to set the indicator for each source storage area and corresponding target storage area in the point-in-time copy relationship to a first value. A determination is made that data was written to one target storage area after establishing the point-in-time copy relationship. The indicators in the source and target relationship data structures corresponding to the source storage area and corresponding target storage area to which data was written are set to a second value.

摘要： In a cache management system multiple cache lists are utilized, where each entry in a list names at least one corresponding data item in cache. A cache manager always demotes cache list entries from a “current removal list” (and demotes or destages the corresponding data items from cache) until that list is exhausted and another list rotates into the function of current removal list. A prescribed order is established for rotating the role of current removal list. In response to prescribed activities of data items in cache, new cache list entries are added nearer or farther from the current removal list according to the prescribed order and the data items' priorities.

摘要： Provided are a method, system, and article of manufacture for adjusting parameters used to prefetch data from storage into cache. Data units are added from a storage to a cache, wherein requested data from the storage is returned from the cache. A degree of prefetch is processed indicating a number of data units to prefetch into the cache. A trigger distance is processed indicating a prefetched trigger data unit in the cache. The number of data units indicated by the degree of prefetch is prefetched in response to processing the trigger data unit. The degree of prefetch and the trigger distance are adjusted based on a rate at which data units are accessed from the cache.

摘要： Provided are a method, system, and program for increasing processor utilization. A list of work is divided for processing among a plurality of processes, wherein a process is allocated a part of the list of work to process, and the processes execute in parallel. If a process completes the list of work allocated to the process then the process is made available on an available process queue. Before a process performs any work, the process reads the available process queue and determines if any process is available to share the work. If so, the work is split up between the examining process and the available process. In one implementation, the work involves scanning a cache and if necessary destage data.

摘要： Provided is a method, system, and program for destaging data from a first computer readable medium to a second computer readable medium. A list of entries indicating data blocks in the first computer readable medium is scanned. For each entry scanned, a determination is made as to whether the data block indicated in the scanned entry satisfies a criteria. If the data block indicated in the scanned entry satisfies the criteria, then a destage operation is called to destage the data block in the scanned entry from the first computer readable medium to the second computer readable medium. If the called destage operation is not initiated, then the scanned entry is removed from the cache list. The removed scanned entry is added to one destage wait list. During one destage operation, data blocks indicated in entries in the destage wait list are destaged.
