  • Patent number: 12353922
    Abstract: A data request that references an external data environment object (foreign object) is identified. A Data Manipulation Language (DML) statement for accessing the object is traversed in a defined order to identify foreign servers having the foreign object. Connections are attempted to foreign servers in the defined order and a selection to one of the foreign servers is made based on server and/or data conditions. The selected server is used for the request to process the portion of the request that includes the foreign object. In an embodiment and during execution of data request, the server and/or the data conditions can be dynamically overridden to change selection criteria for the selected server.

  • Publication number: 20110161877
    Abstract: A system, method, and computer-readable medium that facilitate display of a system configuration are provided. A graphical user interface may provide a display that indicates the position and status of system components and enables a user a convenient mechanism to determine via load group selection a universal power supply load group that is preferred to be connected to a particular chassis power supply, and further provides a mechanism to determine via load group selection which universal power supply load group is connected to a particular chassis power supply. In this manner, a user may confirm a system power supply configuration corresponds to a desired system power supply configuration.
