摘要： A backup operation is performed on a source data set. The data set is segmented into a plurality of blocks. An update bit indicator is implemented for each of the plurality of blocks. The update bit indicator is appended to a field of an existing data index or tied to a mapping table having a relative byte address (RBA). The update bit indicator is set for each of the plurality of blocks which are newly created or changed from a first backup to a second backup, which generates a dump data set containing compressed blocks from the source data set. A backup operation is executed to backup each of the plurality of blocks having the update bit indicator set. The data index or mapping table is updated to show which of the plurality of blocks have changed from the first backup to the second backup.

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： Provided are a computer program product, system, and method for managing traces to capture data for memory regions in a memory. A trace includes a monitor parameter used by a trace procedure to monitor data in a memory device. A frequency is determined at which the trace procedure monitors the memory device. The trace procedure is invoked at the determined frequency to perform trace procedure operations comprising determining a region in the memory device according to the monitor parameter and copying data in the determined region to trace data in a data space.

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.

摘要翻译： 提供了一种用于隔离由独立软件供应商（ISV代码）提供的代码与主供应商提供的代码（主机代码）进行交互时发生的错误的方法。 怀疑含有主机代码的ISV代码的代码被执行。 如果结果错误，则扫描代码，然后与主主机代码进行比较。 任何差异存储在增量文件中，包括主机代码中的ISV代码挂接到主机代码中的位置。 然后修改代码以将钩子旁路到ISV代码以生成一个侧面可执行代码，并执行两个代码并比较结果。 结果没有显着差异表明ISV代码不利地影响主机代码，而结果之间的差异表示修改代码中的错误。
