  • Patent number: 7860824
    Abstract: In a DR system, from the viewpoint of device cost, when search is not carried out, a physical application where log recovery is available by inexpensive DB appliance server is adopted. Further, a local mirror operation at a secondary site is not carried out. Furthermore, from the viewpoint of operation, by a log apply function unit, the tendencies of a log application and operations are monitored, and a search process is accepted according to the progress conditions of the log application. When the log application does not catch up sufficiently, the search is not accepted. Moreover, when a consistency guarantee of a secondary DB is made, not transactions in process at the moment of search instruction are undone (rolled back), but only transactions in process at the moment of a search instruction are redone (rolled forward).

  • Publication number: 20100262862
    Abstract: A computer for the stream data processing system includes a query recovery point management table. A recovery point management section determines a recovery point for the stream data processing system by identifying the oldest one of input tuples used for generating output tuples, which are managed, or an earlier tuple through the use of a query recovery point stored in the query recovery point management table, and transmits the determined recovery point for the stream data processing system to an additional computer. The additional computer stores the last-received recovery point for the stream data processing system in a checkpoint file. When the computer for the stream data processing system recovers from a fault, the additional computer transmits data succeeding the stored recovery point to the computer for the stream data processing system.

  • Publication number: 20100241337
    Abstract: There is a control apparatus of an engine including a variable valve timing mechanism having a locking mechanism for locking a rotation phase of a camshaft with respect to a crankshaft to a target for the engine starting. In a case where the rotation phase has not reached the target for the engine starting at the time of the engine starting, fuel injection to the engine is restricted from the commencement of the engine starting until an integrated value of valve opening frequencies reaches a threshold, and when the integrated value of the valve opening frequencies has reached the threshold, it is regarded that the rotation phase is locked to the target for the engine starting by a locking mechanism, and fuel supply to the engine is permitted.

  • Publication number: 20100232286
    Abstract: Provided is a failure recovery method for switching to a standby system if a failure occurs in an active system, which allows reduction of loads on the standby system and a network. A computer system, which receives data to which timestamp information is appended in a chronological order and processes the received data by registered queries, includes the active system for processing the received data and the standby system for processing the received data instead of the active system upon occurrence of a failure. The active system processes the received data by the respective queries according to a predefined sequence, and transmits results obtained from the received data by the respective queries to the standby system as intermediate data on a query basis at a predetermined timing. The standby system restores the data by processing the received data and the intermediate data if a failure occurs in the active system.

  • Publication number: 20100179742
    Abstract: A method for estimating steady state values of engine operating characteristics is provided so that engine control can later be based on the estimated values. An amount of change in a specific engine characteristic (for which the steady state values are to be estimated) is set as a product of an unknown value and a dimensionless known value for predetermined times from when a specific engine control parameter is changed. A value of the specific engine characteristic at a given time is calculated as a sum of the products at the given time, with the products respectively corresponding to plural prior changes in the specific engine control parameter. Unknown values are calculated multiple times based on values of the specific engine characteristic measured in a conformance test, and the steady state values of the specific engine characteristic are estimated.

  • Publication number: 20100071542
    Abstract: A negative pressure booster according to the present invention is configured in such a manner that a vacuum valve seat member (30) does not move, a reaction disk (25) protrudes and comes into contact only with a reduced diameter portion (24a) of a spacer member (24) under an operation in which an input is equal to or smaller than a preset input. Accordingly, the servo ratio becomes the normal servo ratio. Under the operation in which the input exceeds the preset input, the vacuum valve seat member (30) moves rearward (input side) with respect to a valve body (4) by the pressure in a variable pressure chamber (9), and a reaction disk (25) is significantly protruded to come into contact also with an increased diameter portion (24b) in addition to a reduced diameter portion (24a).
