Abstract: An approach is provided that receives a change request from a requestor. The change request includes metadata regarding the change, one or more changes, and one or more change assumptions corresponding to at least one of the changes. The change request is stored in a data store of pending requests. One or more systems are identified that correspond to each of the change assumptions. The identified systems are automatically queried with queries that correspond to the change assumptions. Query responses in response to the querying are received from the identified systems. The validity of each of the change assumptions is determined based on the received query responses. If the change assumptions are valid, then the changes included in the change request are processed. On the other hand, if at least one of the change assumptions is invalid, then the change request is rejected.

Abstract: A method, computer program product, and system for accessing versioned data objects within a database, comprising creating a first new connection to a database stored in a memory, receiving a first query from a first client that requests access to a versioned data object stored in the database, and modifying the received first query to add contextual information configured on the first new connection, so that the modified first query is able to retrieve a first version of the versioned data object that corresponds to the contextual information.

Abstract: When activities are operated in parallel, and there is only one status display, an ordered list is implemented with three methods of access: insertion at the top, removal from anywhere, and read of the top item. Items kept on this list are the status codes or words for the activities that are currently in progress. When a new activity begins, its status code or word is inserted at the top of the list. Whenever an activity completes, its code or word is removed from the list regardless of its location in the list, and in such a way as to preserve the order of the remaining entries in the list. Whenever the top entry in the list changes (whether through an insertion or removal), the single status display is updated to show the new top value.

Abstract: The present invention discloses a system and method for reserving fractionally schedulable resources. The system includes a scheduling engine to receive reservation requests. The scheduling engine applies the reservation request to a resource usage table corresponding to a fractionally schedulable resource required by the reservation request. If the fractionally schedulable resource has adequate capacity to comply with the requested reservation, the scheduling engine will add the reservation request to a resource usage table.

Abstract: A video network platform manages video network devices with management applications, such as scheduling, monitoring and diagnostics applications, by representing the devices as interface objects that support a network interface module, and application objects used by the management applications and created by an adapter engine that creates an application object for each corresponding video network device interface object. A network interface module associated with the video network platform invokes the adapter engine to create an application object associated with a device. The application object uses its dynamic attribute query capabilities to build an interface object in the network interface module and thus obtain device attributes such as device address information. The application module populates itself with device information for supporting management applications, thus allowing conventional network interface modules to cooperate with application specific objects.
