  • Publication number: 20080229284
    Abstract: Techniques are provided for testing new software slated to be deployed on a target machine population with a number of target machines having a number of existing software programs. Method steps can include obtaining a list of depending software programs on selected ones of the target machines. The list can include those of the existing software programs which depend on the new software and/or those of the existing software programs on which the new software depends. The steps can further include identifying relevant test cases based on the list of depending software programs, instantiating a plurality of test client platforms characteristic of the target machine population, and testing the relevant test cases on the plurality of test client platforms to identify failures.

  • Publication number: 20080052298
    Abstract: A system and method for addressing a node in a tree-like data structure evaluates a relative path expression of a node from one or more marker nodes. In one aspect, a single path expression is determined from a nearby marker node. In another aspect, multiple path expression are determined and resolved to a single path expression. In yet another aspect, the method and system of the present disclosure assign unique identifiers to a subset of nodes in the tree data structure.

  • Publication number: 20030167330
    Abstract: A method, system and computer program for rebinding a binding expression to an appropriate network resource in response to changes in the requirements placed upon the resources or in response to changes in the properties of the currently bound network resource. The binding expression includes a data specification describing the properties required for the resource. Rebinding entails obtaining a list of potential appropriate network resources, selecting an appropriate network resource from the list, and rebinding the binding expression to that resource.

  • Patent number: 6463265
    Abstract: A method, system, and apparatus for handing-off data receivers in a broadcast-based data dissemination environment. Data receiver hand-off is carried out between data sources in different data cells broadcasting information of the same category. Furthermore, data cell ranges are based on geographic regions rather than signal strength coverage. Generally, the hand-off process involves acquiring the current receiver location of the data receiver and comparing the receiver location with a current data cell range. If the current receiver location is outside the current data cell range, a hand-off controller searches for a new data source encompassing the current receiver location coordinates and having an associated data topic matching the current topic. Once a new data source is found, the hand-off controller subscribes the data receiver to the new data source.
