Abstract: A method, system and computer program product for facilitating a meeting is implemented in a server computer and provides a graphical user interface to one or more client devices. The server displays a mind map of a center topic on the clients. The server collects statements of participants, and extracts words and phrases therefrom, to identify topics that are currently being discussed. The server determines whether a transition has occurred between the topics, and then calculates a correlation between the topics that are currently being discussed and the center topic. The server determines a location of the topics that are currently being discussed on the mind map, based on the calculated correlation, and displays an updated mind map on the clients. The server generates a warning on the clients when the server determines that the meeting proceedings are being retarded, based on the calculated correlation.

Abstract: An information providing system and method, including a computer, for providing time taken to read a file, which includes an acquisition unit. The acquisition unit obtains information on a recording position of a file when the file is recorded in a storage device. A recording unit writes information on the obtained recording position to an index referred to access the file. A calculation unit calculates time taken to read the file using the information on the recording position written to the index in response to a request to obtain the time taken to read the file, and providing the calculated time to a requester that requests the time.

Abstract: The present invention may be a method, a system, and/or a computer program product. An embodiment of the present invention provides a computer-implemented method for associating one or more test cases with one or more source code parts for a test target, or vice versa. The method comprises the followings: obtaining one or more historical data in which one or more modification histories made in one or more source codes are associated with one or more test operation histories made in the test target after the one or more modifications; for each of the historical data, determining whether the test operation history has one or more parts which are identical or similar with those in one or more test cases; and if the determination is positive, associating the one or more test cases with one or more source code parts in the one or more modification histories which have been associated with the test operation history, or vice versa.

Abstract: Rolling back data on tape in a file system is provided. A management tape is prepared. The management tape has only index files recorded thereon. The index files contain information about start positions and lengths of corresponding data files recorded on normal tapes. The index files further contain identification information for the normal tapes. A first index file of the management tape is read. The first index file is related to a data file to be rolled back. The first index file is read out from the management tape mounted on a first tape drive. The data file to be rolled back is read out of a first normal tape. The first normal tape is identified based on information in the first index file. The first normal tape is mounted on a second tape drive.

Abstract: Provided is an operating method of a system including a first data processing module, a second data processing module, and one or more data connection modules that transfer data between the first data processing module and the second data processing module. In an operational state where the first data processing module and the second data processing module can process data input thereto, the first data processing module inputs trigger data to any of the one or more data connection modules, and in response to the second data processing module receiving the trigger data via the one or more data connection modules, the second data processing module changes a reading rule for reading data from the one or more data connection modules. Also provided are a system and a computer program product.

Abstract: Communicating data with a medium is provided. A cache is provided for storing target data of a file identified by an access request from an application of a host. The cache is divided into a read cache, a write cache, and an index cache. Responsive to receiving the access request: the medium is loaded onto a drive using a file system; target data is stored to the write cache and to the read cache; and the index file stored in the index cache is updated to reflect position metadata about the target data stored in the write cache. Responsive to initiating unloading of the medium from the drive: the updated index file stored in the index cache is written to the index partition of the medium; and the target data stored in the write cache is written onto a data partition of the medium without using the file system.

Abstract: A method according to one embodiment includes instructing a first tape drive to load a parent tape medium, and instructing the first tape drive to retrieve identification (ID) information about the parent tape medium from metadata stored (saved) thereon. The first tape drive is instructed to write a first file part of a file to the parent tape medium. Information about the file and information about the first file part are written to the parent tape medium as metadata. A second tape drive is instructed to load and retrieve ID information about a child tape medium from metadata stored thereon. The second tape drive is instructed to write one or more subsequent file parts of the file to the child tape medium. The first tape drive is instructed to write the ID information about the child tape medium and attribute information about the one or more subsequent file parts stored to the child tape medium as metadata to the parent tape medium.

Abstract: Restoring a data processing system. Files on one or more storage devices of a data processing system are backed up to magnetic tape recording media. Metadata associated with the backed up files is recorded, including magnetic tape identification and tape location for each backed up file. Files on the one or more storage devices are identified that meet a selection policy for files required for rapid restoration of the data processing system. An index list is generated of the identified files and their associated magnetic tape metadata. The index list is sorted by magnetic tape identification and magnetic tape location. In response to a request to restore the data processing system, the identified files on the sorted index list are restored in magnetic tape identification and magnetic tape location sort order. Operation of the restored data processing system is then begun in accordance with the restored files.

Abstract: One or more processors receive data records from a file system, and convert the data records to a tape image having a format defined by the file system. The tape image is written to a first storage device, and a sequence of data types of the first storage device and a second storage device are monitored to determine whether the first storage device sequence of data types differs from the sequence of data types of the second storage device. Determining that the sequence of data types of the first storage device and second storage device do differ, one or more processors copying, to the second storage device, the data records from the first storage device, from the position on the first storage device that corresponds to the end-of-data position of the second storage device, to the end-of-data position of the first storage device.
