Abstract: Useful work or services can be automated or otherwise facilitated or solutions to real world events developed by emulation of a real-world environment (which can contain objects representing virtual objects) with a virtual environment and generating a prioritized sequence of locations and associated tasks in accordance with resources related to the event in a virtual universe. Performance of the prioritized tasks at the prioritized locations is facilitated in the virtual universe by locally generating teleportation invitations corresponding to locations in the ordered sequence of locations.

Abstract: In some embodiments, a method comprises hosting a virtual universe in which one or more avatars interact with one or more virtual objects. The method can also include presenting energy conservation options that reduce amounts of power consumed in rendering the avatars and virtual objects in the virtual universe, detecting a selection of the energy conservation options, and configuring logic for rendering the avatars and virtual objects according to the selected energy conservation options. The method can also comprise rendering, according to the selection of energy conservation options, the avatars and virtual objects in the virtual universe.

Abstract: In an embodiment, a first debug agent at a first computer receives a packet. The first debug agent adds a debug command and an identifier of the first debug agent to the packet and sends the packet to a receiving computer. A second debug agent at the receiving computer removes the debug command and the identifier of the first debug agent from the packet and sends the packet to a second program that executes at the receiving computer. The second debug agent further executes the debug command, which causes the second program that executes on the receiving computer to halt execution at a breakpoint or address watch memory location. The second debug agent sends the state of the second program to the first debug agent, which presents, at the first computer, the state and a listing of the second program.

Abstract: Implementation primitives for concurrent array-based stacks, queues, double-ended queues (deques) and wrapped deques are provided. In one aspect, each element of the stack, queue, deque or wrapped deque data structure has its own ticket lock, allowing multiple threads to concurrently use multiple elements of the data structure and thus achieving high performance. In another aspect, new synchronization primitives FetchAndIncrementBounded (Counter, Bound) and FetchAndDecrementBounded (Counter, Bound) are implemented. These primitives can be implemented in hardware and thus promise a very fast throughput for queues, stacks and double-ended queues.

Abstract: A database access facility for accessing databases includes a monitoring function which monitors accesses by requestors of database data. The monitoring function tracks which database fields are requested to dynamically determine the fields which the application needs. Once sufficient tracking data is obtained, subsequent accesses to the database on behalf of an application are automatically modified by the application server to request only the fields which are likely to be needed. Preferably, the database access facility is an application server for one or middle tier applications which access the database on behalf of multiple clients in a three-tier client-server environment.

Abstract: A computer system includes a first electronic device having a first display. The first display includes a first electronic image having an anchor point. The computer system also includes a second electronic device that is moveable relative to the first electronic device. The second electronic device includes a movement sensor and a second display operatively connected with the first display. The second display includes a second electronic image that is associated with the first electronic image. Upon sensing movement of the second electronic device relative to the first electronic device, the movement sensor determines a direction of the movement relative to the anchor point and triggers a shifting of the second electronic image relative to the anchor point of the first electronic image.

Abstract: In an embodiment, a selection of an original transaction is received. In response to the selection of the original transaction, a call stack of the application that sends the original transaction during a learn mode of the application is saved. A specification of a new transaction and a location of the new transaction with respect to the original transaction in an transaction stream is received. During a production mode of the application, the original transaction is received from the application. A determination is made that the call stack of the application during the production mode matches the saved call stack of the application during the learn mode. In response to the determination, the new transaction is inserted at the location into a transaction stream that is sent to a database.

Abstract: Real world energy usage can be reduced using a virtual environment. A virtual universe energy conservation system (“system”) can determine comprehensive energy usage at a physical site where a client accessing a virtual universe is located. The system can determine that the comprehensive energy usage at the physical site exceeds an energy usage threshold. The system can also notify a virtual universe user account associated with the client that the comprehensive energy usage at the physical site exceeds the energy usage threshold.

Abstract: In an embodiment, a request is received that is directed to a page. A determination is made whether a session associated with the request already exists by determining whether the request is dependent on a previous request. If the session does not already exist, then a decision is made whether the request will result in creating a session. If the request will result in creation of a session, then a server is selected based on a load-balancing metric instance associated with the page, and the request is sent to the selected server. The load-balancing metric instance has an algorithm and an input parameter to the algorithm. The server is selected by executing the algorithm and selecting the server identified by an output parameter from the algorithm.
