  • Building a synchronized target database
    Patent number: 7974943
    Abstract: One embodiment is a method that builds a target database with transaction logs from an online source database. The transaction logs include both existing data in the source database and updates that occur to the source database while the target database is being built.
    Type: Grant
    Filed: October 30, 2008
    Date of Patent: July 5, 2011
    Assignee: Hewlett-Packard Development Company, L.P.

  • Efficient transfer of data and events between processes and between processes and drivers in a parallel, fault tolerant message based operating system
    Publication number: 20010023467
    Abstract: A parallel, fault-tolerant computer system in which data is transferred between processes in a single CPU by two methods. In a first method, the data is copied each time it is transferred. In a second method, the data is not copied, but is passed through a shared memory, queueing system. The first method is used to ensure fault-tolerance and linear expandability. The second method is used to minimize the time required for inter-process communication. Use of the shared memory queueing system allows for faster communication between processes executing in a same CPU.

  • Computer system data I/O by reference among I/O devices and multiple memory units
    Patent number: 5954794
    Abstract: An apparatus and method for getting descriptors to data and passing the descriptors among data sources and sinks, thereby avoiding copying the data among the data sources and sinks. The data source/sink which consumes the data actual initiates the copying of the actual data itself, using global pointers to the data in the descriptors.
    Type: Grant

  • System for transferring a data stream to a requestor without copying data segments to each one of multiple data source/sinks during data stream building
    Patent number: 5941959
    Abstract: An apparatus and method for getting descriptors to data and passing the descriptors among data sources and sinks, thereby avoiding copying the data among the data sources and sinks. The data source/sink which consumes the data actual initiates the copying of the actual data itself, using global pointers to the data in the descriptors.

  • Computer system data I/O by reference among multiple CPUS
    Patent number: 5931903
    Abstract: An apparatus and method for getting descriptors to data and passing the descriptors among data sources and sinks, thereby avoiding copying the data among the data sources and sinks. The data source/sink which consumes the data actual initiates the copying of the actual data itself, using global pointers to the data in the descriptors.

  • System for transferring data over a network in which a data source sends only a descriptor which a data sink uses to retrieve data
    Patent number: 5852719
    Abstract: An apparatus and method for getting descriptors to data and passing the descriptors among data sources and sinks, thereby avoiding copying the data among the data sources and sinks. The data source/sink which consumes the data actual initiates the copying of the actual data itself, using global pointers to the data in the descriptors.
