    摘要: The data ETL (Extraction-Transformation-Loading) dispatching method of the present invention is applied to a real-time data ETL system, wherein a main ETL dispatching engine executes tasks according to preset sequence. In the execution, some key information are memorized by the main ETL dispatching engine, such as lscycle (latest successful data cycle), curcycle (current processing data cycle), and endcycle (processing end data cycle), etc., and are transferred to called programs. After the execution of the called programs, the main ETL dispatching engine records and keeps the updated dispatching information. In the data re-extraction, the data ETL dispatching method is adopted for the automatic re-extraction of some tasks and some cycles therein. The data ETL dispatching method, solves the problem caused by cyclic closed-loop extraction in traditional ETL dispatching programs according to timestamps in the real-time data ETL system, simplifies the tasks of the called program by allowing the called programs to focus on its own business logic, thereby giving sufficient development time for the real-time data ETL field, resulting in greatly enhancing the efficiency of project implementation.

    摘要: Anti-channeling pack-off particles used in a production section of an oil-gas well, a completion method, and a production method are provided. The anti-channeling pack-off particles are macromolecule polymer particles having an average particle diameter of 0.05-1.0 mm and a real density of 0.8-1.4 g/cm3. The particles are compactly filled into a space of the oil-gas well, which is required to be filled and packed off so that there is no channeling path after filling, thus effectively pack-off or sectioning the oil-gas well into multiple, relatively independent regions for production from the oil-gas well, and thus improving the production efficiency of the oil-gas well. Even if a channeling path occurs, a very small flow of channeling fluid of a carrier medium will move some of the anti-channeling pack-off particles in a direction towards the channeling path and accumulate those particles until the channeling path is filled, thereby achieving favorable effects of anti-channeling, packing-off, and sectional flow control.

    摘要: A technique performs policy-based intelligent data placement in an electronic environment. The technique involves selecting, from a pool of candidate local area networks (LANs) of the electronic environment, a plurality of LANs within which to store the data based on a set of policy priority levels assigned to the data. The technique further involves generating a set of information elements (e.g., data fragments, erasure codes, etc.) from the data, and placing the set of information elements on storage nodes of the plurality of LANs. Such a method enables the data to be stored in a distributed manner and alleviates the need for a central storage facility. Since the data is distributed among the storage nodes of the plurality of LANs, system capacity and infrastructure is able to grow (i.e., scale) in a manner which does not create a problematic bottleneck.

    摘要: An overlay network has a hierarchical cluster tree (HCT) structure on an underlying physical network, the HCT structure having clusters of local area networks (LANs) associated with respective sub-spaces of a hash key space. A cluster proxy node (CP) maintains a routing table and channels to both a parent cluster and member LANs, with routing information associating each LAN with a physical-network address (PA) of a corresponding LAN representative node (LR). Nodes sending routing request messages each containing a key value to the CP node, which returns routing response messages each including PA information from the routing table and/or the parent cluster. The PA information in the response for a given request includes a PA of an LR of a request-specific LAN whose sub-space contains the key value in the request message. A node uses the PA information to send a message to the LR node using the physical network.
