Abstract: PROBLEM TO BE SOLVED: To provide a point in time copy of data between a source data storage system and target data storage system. SOLUTION: Information which correlates logical identification of a point in time copy data with the point in time copy data stored in a target and source is established in a target, and the information refers to the data storage system which has the required point in time copy data. A controller of the target accesses the point in time copy data required by the target when a table indicates the required point in time copy data is available at the target, if not, obtains the required point in time copy data from the source via a peer to peer communication link interface.

Abstract: PROBLEM TO BE SOLVED: To provide the programming aid which makes it possible to view a computer program in source code format by using a general-purpose document browser. SOLUTION: This programming aid is equipped with a purser 100 which generates a symbol table 120 from an input file 110 containing a program, a means which extracts the position of a control tag from the symbol table 120, and an output file generator which generates an output file that can be viewed through the general-purpose document browser by inserting the control tag into the program according to the extracted position. Then a tool is provided which automatically marks up the program with the control tag, and a user can use a freely an optionally selected document browser as a powerful program browser.

Abstract: A method and system disclosed for enhanced efficiency of backup copying of designated datasets stored within storage devices (61) coupled to the data processing system via a storage control unit (65) having memory (66) therein. Application execution is temporarily suspended to form a dataset logical-to-physical address concordance to be utilized to administer backup copying. Application initiated updates to uncopied portions of the designated datasets are temporarily deferred until sidefiles of the affected portions are written to memory (66). Portions of the designated datasets are then accessed and copied utilizing selected data retrieval command sequences. A sidefile status query is appended to said command sequences and the presence of data within memory (66) is determined. The sidefiles are then accessed and copied to alternate storage locations in a backup copy order defined by the address concordance.

Abstract: An "on-line" data protection apparatus for secondary storage devices involves placing encryption/decryption hardware (23) inside the I/O subsystem (2) which forms the interface between the host computer (1) and the secondary storage devices (3a-3n). All data being transferred between the host computer and the storage devices is encrypted/decrypted by this hardware. The circuit may also compress/decompress the data.

Abstract: Disclosed is a programming aid for enabling computer program source code to be viewed using a general purpose document browser responsive to a defined set of control tags determining the appearance of a document, the aid comprising: a parser for generating a symbol table from an input file in which the program is stored; means to derive control tag locations from the symbol table; and an output file generator for inserting, 530, control tags into the program at the derived locations to generate an output file which can be viewed using the general purpose document browser. In this way, the full power of user-chosen general purpose document browsers may be used in software development and maintenance to view programs in a convenient way.

Abstract: A data storage disk device for a RAID disk array is disclosed, comprising a rotatably mounted disk having a data storage surface; a first head for reading data from and writing data to the data storage surface; characterised by a second head for reading data from the data storage surface; and control means for executing a write operation to a sector, said write operation including reading the contents of the sector via the second head for subsequent processing and writing new data to the sector via the first head, the first and second heads being arranged with respect to the data storage surface so that the new data can be written to the sector on the same revolution of the disk as the reading operation. The addition of a second head to the disk storage device improves the performance of the disk device for RAID applications.

Abstract: A backup method for a computer database system in which updates to the mirrored data of a remote database are delayed for a delay time greater than or equal to the communication delay between the local and remote databases and updates to a remote log for the database are executed after corresponding updates to a local log without such a delay. In this way a consistent copy of the database may be recovered from the mirrored copy of the database and the remote log after destruction of the database system.

Abstract: Disclosed is a programming aid for enabling a computer program in source code form to be viewed using a general purpose document browser, which browser is responsive to a defined set of control tags determining the appearance of a document thereon, the programming aid comprising: a parser for generating a symbol table from an input file in which the program is stored; means to derive control tag locations from the symbol table; and an output file generator for inserting control tags into the program at the derived locations to generate an output file which can be viewed using the general purpose document browser. In this way, the full power of available general purpose document browsers may be used in software development and maintenance to view programs in a convenient way. A tool is provided that automatically marks up a program with control tags so that users are free to use the document browser of their choice as a powerful program browser.
