  • Enhanced system and method for management of system database utilities
    Patent number: 6411969
    Abstract: An enhanced method for developing back-up copies of a source database by providing incremental and accumulate dump commands from various multiple-Users which enable a selection of certain files which are identified independently of time-factor for dumping selectively either onto a separate destination medium of disk or tape. A User can determine the block size of words for blocks of data files to be dumped onto the destination medium, thus significantly reducing the number of I/O operations required.
