Abstract: Provided are methods, data processing systems and computer program product for monitoring user activity and monitoring the effectiveness of objects within a virtual environment such as an immersive, computer-simulated 3D environment. An embodiment of the invention monitors the attention given to a virtual object by one or more avatars, by associating a viewing region with each object that requires attention monitoring, and detecting when an avatar is within the viewing region of the object simultaneously with the object being within an attention region (typically a clipped field of view) of the avatar. The viewing region is a 3D volume within which a surface of the virtual object is deemed to be effectively viewable.

Abstract: The different illustrative embodiments provide a method, computer program product, and apparatus for converting a first image for a virtual machine formatted for a first virtual environment. A second image is created, wherein the second image is non-specific to any virtual environment. A determination is made whether a portion of files to be copied from the first virtual image to the second virtual image should be replaced using a compatibility matrix, wherein the compatibility matrix identifies changes between the first virtual environment and a second virtual environment. A replacement for the portion of the files is copied to the second image using the compatibility matrix responsive to a determination that the portion of the files in the set of files should be replaced. The file is copied to the second image responsive to an absence of a determination that the each file in the set of files should be replaced.

Abstract: A method and system for optimizing SQL queries for Simple Network Management Protocol (SNMP) Management Information Base (MIB) tables. An SNMP client receives a source query defined in structured query language to access data stored in one or more MIB tables. The SNMP client parses the source query into one or more queries and sub-queries and applies sets of optimization rules and heuristics to the source query to generate a query execution plan for each set of optimization rules and heuristics applied to the source query. The SNMP client selects an optimal query execution plan from the generated query execution plans and rewrites the source query as a SNMP-based query using the optimization rules and heuristics specified in the optimal query execution plan. The SNMP-based query may then be used to retrieve the data requested by the source query without performing a full query scan of the MIB tables.

Openings may be in the first and second numbers of skin panels. The openings may be in locations such that each bay has an opening and such that the openings may alternate between the first side and the second side between adjacent bays in the bays. The frame may be attached to the fuselage using the openings to access an interior of the frame.

Abstract: An interface is provided between a virtual cluster proxy and a virtual I/O server on a logical partitioned platform. The virtual I/O server is configured to support virtual real memory. A command is received from a virtual cluster proxy. The virtual cluster proxy identifies whether the command is a virtual real memory command or a virtualization command. Virtual real memory commands and virtualization commands are marked by the virtual cluster proxy with a virtualization marker. The virtualization marker indicates that the command is a virtual real memory command or a virtualization command. The command is then forwarded to a logical partitioned platform. A virtual memory manager intercepts the command and identifies whether the command has been marked with the virtualization marker. If the command is marked with the virtualization marker, the virtual memory manager reroutes the command to the virtual I/O server.

Abstract: Identifying traffic patterns to web sites based on templates that characterize the arrival of traffic to the web sites is provided. Based on these templates, determinations are made as to which web sites should be co-located so as to optimize resource allocation. Web sites whose templates are complimentary, i.e. a first web site having a peak in arrival traffic at time t1 and a second web site that has a trough in arrival traffic at time t1, are designated as being candidates for co-location. In addition, the templates identified for the traffic patterns of web sites are used to determine thresholds for offloading traffic to other servers. These thresholds include a first threshold at which offloading should be performed, a second threshold that takes into consideration the lead time needed to begin offloading, and a third threshold that takes into consideration a lag time needed to stop offloading of traffic.

Abstract: A system for automatically replacing loaner parts within a loaner system to prevent loaner system callback. In response to selecting a loaner system within loaner inventory data, it is determined whether the selected loaner system is required to be returned based on a target return date for the selected loaner system. In response to determining that the selected loaner system is not required to be returned, a notification is automatically generated and sent to a customer to return expiring loaner parts within the selected loaner system based on loaner part rules. A part replacement order is automatically generated for replacement loaner parts for each of the expiring loaner parts. Then, the replacement loaner parts are automatically shipped to the customer to replace the expiring loaner parts to prevent callback of the selected loaner system.

Abstract: A multi-mode register rename mechanism which allows a simultaneous multi-threaded processor to support full out-of-order thread execution when the number of threads is low and in-order thread execution when the number of threads increases. Responsive to changing an execution mode of a processor to operate in in-order thread execution mode, the illustrative embodiments switch a physical register in the data processing system to an architected facility, thereby forming a switched physical register. When an instruction is issued to an execution unit, wherein the issued instruction comprises a thread bit, the thread bit is examined to determine if the instruction accesses an architected facility. If the issued instruction accesses an architected facility, the instruction is executed, and the results of the executed instruction are written to the switched physical register.
