摘要： One embodiment is for using a sparse file as a clone. The method includes creating, by an application associated with a computer system, a snapshot of a file, such as an individual file, a collection of files, file system, directories, and so forth. Further, the method includes requesting, by the application, a clone of that created snapshot. Further still, the method includes generating, by the application, an empty sparse having at least one inode identifying the empty sparse file as the clone and pointing to the snapshot associated with the clone. Thereby, the requested clone is created using the created sparse file, which begins as an empty sparse file.

摘要： Disclosed is a computer implemented method to resume a process at an arrival machine that is in an identical state to a frozen process on a departure machine. The arrival machine receives checkpoint data for the process from the departure machine. It creates the process. It updates a page table, wherein the page table comprises a segment, page number, and offset corresponding to a page of the process available from a remote paging device, wherein the remote paging device is remote from the arrival machine. It resumes the process and responsively generates a page fault for the page. It looks up the page in the page table, responsive to the page fault. It determines whether the page is absent in the arrival machine. It transmits a page-in request to the departure machine, responsive to a determination that the page is absent. It receives the page from the departure machine.

摘要： Embodiments include a method comprising detecting addition of a new nonvolatile machine-readable medium to a data storage pool of nonvolatile machine-readable media. The method includes preventing from being performed a first operation of a file system that requires a first parameter that identifies a logical indication of a location within the nonvolatile machine-readable media for the file system, until logical indications of locations within the new nonvolatile machine-readable medium for the file system have been stored in the data storage pool. The method includes allowing to be performed, prior to logical indications of locations within the new nonvolatile machine-readable medium being stored in the data storage pool, a second operation of the file system that does not require a second parameter that identifies a logical indication of a location within the nonvolatile machine-readable media, wherein the second operation causes data to be written into the new nonvolatile machine-readable medium.

摘要： Some embodiments of the inventive subject matter are directed to performing sub-transactions of a long-lived transaction (LLT) in a sequence (e.g., according to an LLT flow) and writing a log entry at the performance of each of the sub-transactions that specifies results of the sub-transaction. Some embodiments do not require generating any compensating transactions during performance of the sub-transactions. Some embodiments are further directed to detecting that an interruption occurs to the LLT and repeating, or initiating re-performance of the LLT from the beginning of the sequence following the flow of the LLT from its beginning. During the re-performance of the LLT, some embodiments are further directed to checking the log entry at each sub-transaction to determine whether the sub-transaction was performed successfully before the interruption. If the log indicates that the long-lived transaction completed successfully, some embodiments are further directed to skipping performance of the sub-transaction until reaching a sub-transaction that does not have a valid log entry, then returning an error and recovering the LLT using instructions for compensating transactions that are already written into the LLT flow.
摘要翻译：本发明主题的一些实施例涉及以序列（例如，根据LLT流）执行长时间事务（LLT）的子事务，并且在执行每个子事务时写入日志条目它指定子事务的结果。一些实施例不需要在执行子事务期间生成任何补偿事务。一些实施例进一步涉及检测到在LLT从其开始流动之后中断发生到LLT并重复或者从序列开头重新开始LLT的重新执行。在LLT的重新执行期间，一些实施例进一步涉及在每个子事务处检查日志条目以确定子事务是否在中断之前成功执行。如果日志指示长时间的事务成功完成，则一些实施例进一步涉及跳过子事务的性能，直到达到不具有有效日志条目的子事务，然后返回错误并使用用于补偿已经写入LLT流中的事务的指令。

摘要： A distrbuted services program installed on each of a plurality of data processing systems in a network allows the processors to access data files distrbuted across the various nodes of the network.To reduce the network traffic overhead when files at other nodes are accessed, and to preserve the file system semantics, i.e. the file integrity, the accessing of the various files are managed by file synchronization modes. A file is given a first synchronization mode if a file is open at only one node for either read or write access. A file is given a second synchronization mode if a file is opened for read only access at any node. A file is given a third synchronization mode if the file is open for read access in more than one node, and at least one node has the file open for write access.If a file is in either the first or second synchronization mode, the client node, which is the node accessing the file, uses a client cache within its operating system store the file. All read and writes are then sent to this cache.If a file is in the third mode, all read and write requests must go to the server node where the file resides. The node accessing the file does not use the cache in its operating system to access the file data during this third mode.

摘要： In order to avoid the problem of the last line of the body text not being justified when it is not the end of a paragraph but is followed by a footer, a converter/processor (13) is provided to modify the print data stream produced by another converter/processor (12) from the revisable or editable text data stream. If during conversion from the revisable data stream to the print data stream a "last body text line" is found and it is not the end of a paragraph, a latch (34) is set. Then, with each line of print data stream text, the latch is checked, and if the latch is set and the text line ends with a carriage return, the carriage return is replaced with a zero-index-carriage return and an index. These act similar to a carriage return in all cases except one--the text line which they terminate may now be justified.
