  • Patent number: 7672228
    Abstract: Embodiments of the invention are generally directed to a system and method of network loop detection and recovery. In one embodiment of the invention, a networked node contains a loop detection and recovery agent. The loop detection and recovery agent may include a loop detection module and a loop recovery module. The loop detection module may be independent of a redundancy protocol implemented by the networked node. In contrast, the loop recovery module may be embedded in the redundancy protocol implemented by the networked node.

  • Publication number: 20060195436
    Abstract: The present invention provides in-place, phased migration from one version of a database software application release version to another of a software release version. A method for phased migration of a database software application comprises developing a database software application in a plurality of phases of development, at least some of the plurality of phases of development requiring a change in a schema of a database used by the database software application; and for each of the phases of development that requires a change in a schema of the database, performing phase-wise migration of the database by sequentially modifying the schema of the database based on the changes in the schema of the database required by each phase.
