Patent number: 7103612Abstract: A method and system are provided for instantiating objects for participation in information sharing relationships. According to one technique, a copy of an object is made, where the copy includes all changes made prior to a particular point in time, and no changes made after the particular point in time. The copy is used to create a second object. Data that reflects the particular point in time is stored, and subsequently used to determine which changes should be applied to the second object. Data that indicates that the creation time of the second object is stored, and subsequently used to determine which changes should be applied to the original object.Type: GrantFiled: March 26, 2003Date of Patent: September 5, 2006Assignee: Oracle International CorporationInventors: Wayne E. Smith, Jing Liu, James Stamos, Mahesh Subramaniam

Patent number: 6792540Abstract: An approach is described for improved security during data replication, in which a refresh program runs in the security domain of a trusted user. The refresh program first checks to see if the requesting user actually owns the snapshot before reconciling differences in refreshing a snapshot. Untrusted users are granted only connect privileges and the ability to run a refresh program.Type: GrantFiled: May 28, 1999Date of Patent: September 14, 2004Assignee: Oracle International CorporationInventors: Wayne E. Smith, Alan Robert Downing

Patent number: 6697804Abstract: Mass deployment of snapshots is fostered by allowing collections of snapshots, called refresh groups, to be defined by a template. The template allows for a parameterized snapshot definition query or other DDL text to be defined, so that user-specific or site-specific values can be substituted into parameters to create different objects. Furthermore, off-line instantiation of snapshots is provided, so that the data for an entire suite of front office applications can be stored. on a floppy disk, magnetic disk, CD ROM, or other transportable computer-readable medium.Type: GrantFiled: November 14, 2002Date of Patent: February 24, 2004Assignee: Oracle International Corp.Inventors: Curtis Elsbernd, Benny Souder, Wayne E. Smith

Patent number: 6532479Abstract: Replication for front office automation involves the use of snapshots that are instantiated on laptops, in which refreshing the snapshots is driven from a master site with a high-performance protocol. All of the necessary snapshot metadata for performing the snapshot refreshes is stored at the master site, so that the laptop only needs to send a single refresh request. In response to the refresh request, the master site reconciles the differences between the master tables and the laptop's snapshots and transmits the differences to the laptop, reducing the necessary network traffic for updating a snapshot to a single round trip.Type: GrantFiled: May 28, 1999Date of Patent: March 11, 2003Assignee: Oracle Corp.Inventors: Benny Souder, Alan Robert Downing, Harry Sun, Alan J. Demers, James William Stamos, John C. Graham, Curtis Elsbernd, Mahesh Subramaniam, Wayne E. Smith

Patent number: 5265042Abstract: This invention describes a nonlinear comb filter device and a method for removing harmonic interference from a corrupted signal. Here, a corrupted signal is defined as a signal containing an impulsive signal and harmonic interference. The corrupted signal is delayed through a delay line. The delay line has a plurality of tapped output terminals each spaced at a delay time that is a multiple of the fundamental period of the harmonic interference. An odd number of taps is preferred for ease of sampling and ease of performing certain nonlinear functions such as a median. Each delay line tap is connected to a corresponding input to a nonlinear device. A median device is one possible embodiment of a nonlinear device. The delay line and the nonlinear device extract the harmonic interference from the corrupted signal.Type: GrantFiled: August 20, 1992Date of Patent: November 23, 1993Assignee: The United States of America Government as represented by the Director, National Security AgencyInventor: Wayne E. Smith, Jr.
