摘要： A data path controller, a computer device, an apparatus and a method are disclosed for integrating power management functions into a data path controller to manage power consumed by processors and peripheral devices. By embedding power management within the data path controller, the data path controller can advantageously modify its criteria in-situ so that it can adapt its power management actions in response to changes in processors and peripheral devices. In addition, the data path controller includes a power-managing interface that provides power-monitoring ports for monitoring and/or quantifying power consumption of various components. In one embodiment, the data path controller includes a power-monitoring interface for selectably monitoring power of a component. It also includes a controller for adjusting operational characteristics of the component for modifying the power consumed by the component to comply with a performance profile, which generally specifies permissible power consumption levels for the component.

摘要： Provided are a computer program product, system, and method for allowing writes to complete without obtaining a write lock to a file. A lock is provided to a first request, comprising a read or write request, to access the file. A second write request is received while the first request maintains the lock. A temporary file associated with the file for the second write request is created. The second write request is controlled to write to the temporary file while the lock is held by the first request. In response to completing the first request, the lock is granted to the second write request to write the data in the temporary file to the file.

摘要： Providing a computer program product, system, and method for logging updates to monitored data sets in a storage. A request is received to monitor changes to a monitored data set comprising one of the data sets in the storage. A determination is made of tracks in the storage in which the data set is stored. The determined tracks are indicated in monitored tracks. Updates to the storage are received and a determination is made as to whether the updates are for the monitored tracks. The updates are logged in response to determining that updates are for the monitored tracks. A determination is made of new tracks added to the monitored data set and the determined new tracks are indicated in the monitored tracks.

摘要： An approach to selectively recording trace data. The approach sifts through process control and state data to store data that is most relevant to aiding debugging while reducing the overall amount of data that is stored in a trace data set by a trace facility. The approach may involve initiating a trace operation for the software component and, for each resource of the software component, determining whether the resource is currently in use. For those resources in use, the current state of the resource is compared with the previous state of the resource. If the current state has changed, the current state is written to the trace data set. If the resource is not in use, or the current state has not changed, no entry is made to the trace data set. The approach may also analyze users to determine which resources the users are holding and/or waiting for.

摘要： An approach to allocating storage that has track managed storage and cylinder managed storage. The approach involves receiving a request to allocate a data set for new data and determining if the size of the new data exceeds a breakpoint value. The size of the new data may be determined by allocating a buffer data set that is the size of the breakpoint value, and writing the new data to the buffer data set. If the new data only partially fills the buffer data set, then the size of the new data is smaller than the breakpoint value. If the new data overfills the buffer data set, then the size of the new data set is larger than the breakpoint value. New data that is larger than the breakpoint value is automatically stored in cylinder managed storage, while new data that is smaller than the breakpoint value is automatically stored in track managed storage.

摘要： A method is provided for isolating errors which occur when code supplied by independent software vendors (ISV code) interacts with code supplied by a primary vendor (host code). Code suspected of containing ISV code with host code is executed. If the results are in error, the code is scanned and then compared with a master host code. Any differences are stored in a delta file, including locations in the host code where ISV code hooks into the host code. The code is then modified to by-pass the hooks to ISV code to generate a side-executable code and both codes are executed and the results are compared. A lack of substantial difference in the results is indicative that the ISV code adversely affects the host code while a difference between the results is indicative of an error in the modified code.
