  • Patent number: 6904544
    Abstract: Provided is a method, system, program, and data structures for maintaining a database of objects. At least one structured document is received representing an instance of an object including attributes and attribute values defined for a class. Content of the structured document representing the object is added into a database, wherein the database is capable of storing multiple structured documents representing multiple objects. In another implementation, an instance of at least one object including attributes and attribute values defined for a class is generated. For each generated object, a structured document is generated representing the object and including a representation of the attributes and attribute values in the object. Each structured document is transferred to a database program to maintain.

  • Publication number: 20020129230
    Abstract: Provided is a computer implemented method, system, and program for determining system information, wherein the system is comprised of at least one host adaptor, switch, and storage device. A path in the system from one host adaptor to the I/O device includes as path components one host adaptor, one switch, one storage device, a first link between the host adaptor and the switch and a second link between the switch and the storage device. A determination is made of component information on host adaptor, switch, and I/O device components in a network system. The determined component information is added to a configuration file providing configuration information on the system. For each determined host adaptor, a determination is made from the component information of information on the first link between the host adaptor and the switch and on the I/O device to which the host adaptor communicates.

  • Patent number: 6442670
    Abstract: A data processing system comprises a plurality of nodes and a serial data bus interconnecting the nodes in series in a closed loop, for passing address and data information. At least one processing node includes a processor, a printed circuit board and a memory which is partitioned into a plurality of sections, including a first section for directly sharable memory located on the printed circuit board, and a second section for block sharable memory. A local bus connects the processor, block sharable memory and printed circuit board, for transferring data in parallel from the processor to the directly sharable memory on the printed circuit board, and for transferring data from the block sharable memory to the printed circuit board.

  • Patent number: 6134647
    Abstract: A data processing system includes a plurality of nodes, a serial data bus interconnecting the nodes in series in a closed loop for passing address and data information, and at least one processing node. In one construction, this processing node has a processor, a printed circuit board, a memory partitioned into first and second sections and a local bus connecting the processor, a block sharable memory section of the memory, and the printed circuit board. The local bus is used for transferring data in parallel from the processor to a directly sharable memory section of the memory on the printed circuit board and for transferring data from the block sharable memory to the printed circuit board.
