20090138556 | SYSTEM AND METHOD FOR IMPLEMENTING QUICK RESPONSE REPLIES ON A DATA PROCESSING SYSTEM - A system and method for implementing quick response replies on a data processing system. According to an embodiment of the present invention, a user drafts a current message within a current window of an instant messaging (IM) client, wherein the current message is targeted to a current user. In response to receiving a new message when the current message is partially drafted, the user drafts a new reply message to respond to the new message while preserving the partially-drafted message. The IM client sends the new reply message to respond to the new message. The user completes the partially-drafted current message and the IM client sends the completed current message to the current user. | 05-28-2009 |
20090300092 | ENHANCING REAL-TIME PERFORMANCE FOR JAVA APPLICATION SERVING - A method, system, and computer-readable medium with executable code for enhancing real-time performance of a client device connected to a java virtual machine by incorporating a java proxy server. Java routing logic of a java proxy server is used to receive a request from a client device to access a java virtual machine. The java proxy server may use the java routing logic to select a java virtual machine from among multiple accessible java virtual machines. The java proxy server selects the java virtual machine that has the greatest amount of free memory, and is not performing a garbage collection operation. Once a java virtual machine is chosen, incoming client device connections are routed to a chosen java virtual machine. Additionally, the java routing logic may instruct one or more of the multiple java virtual machines to only perform garbage collection operations when idle, and when no other java virtual machines are performing garbage collection operations. | 12-03-2009 |
20100057881 | Migration of a Guest from One Server to Another - Systems, methods and media for migration of a guest from one server to another are disclosed. In one embodiment, a first server, while hosting the guest, receives a signal from the second server that the migration is to occur. The first server presents the memory used by the guest as a virtual disk. The second server accesses this disk and copies its contents to the second server over the storage area network. The first server suspends operation of the guest, and after the memory of the guest is copied to the second server, the second server resumes operation of the guest. | 03-04-2010 |
20100058358 | METHOD AND APPARATUS FOR MANAGING SOFTWARE CONTROLLED CACHE OF TRANSLATING THE PHYSICAL MEMORY ACCESS OF A VIRTUAL MACHINE BETWEEN DIFFERENT LEVELS OF TRANSLATION ENTITIES - A method and a system for allowing a guest operating system (guest OS) to modify an entry in a TLB directly without an involvement of a hypervisor are disclosed. Upon receiving a guest TLB miss exception, a guest OS issues a TLBWE (TLB Write Entry) instruction to logic. The logic executes the TLBWE instruction at a supervisor mode without invoking a hypervisor. The TLB may incorporate entries in a guest page table and entries in a host page table. | 03-04-2010 |
20110145471 | METHOD FOR EFFICIENT GUEST OPERATING SYSTEM (OS) MIGRATION OVER A NETWORK - A method, data processing system and computer program product enables efficient transfer of a virtual machine from a first data processing system (DPS) to a second DPS using a combination of Transmission Control Protocol (TCP) and Uniform Data Protocol (UDP). A virtual machine migration (VMM) utility identifies all memory pages of the first virtual machine. The VMM utility notifies the second DPS via TCP of the scheduled transfer of the virtual machine. The VMM utility copies and transfers the memory pages of the virtual machine to the second DPS via UDP. When all expected components of the virtual machine are not received by the second DPS and/or memory data is modified within the memory pages during the migration, the VMM utility combines the missing data and the modified data and transfers the final components of the virtual machine using TCP. Execution of the virtual machine resumes on the second DPS. | 06-16-2011 |
20130007408 | METHOD AND APPARATUS FOR MANAGING SOFTWARE CONTROLLED CACHE OF TRANSLATING THE PHYSICAL MEMORY ACCESS OF A VIRTUAL MACHINE BETWEEN DIFFERENT LEVELS OF TRANSLATION ENTITIES - A method and a system for allowing a guest operating system (guest OS) to modify an entry in a TLB directly without an involvement of a hypervisor are disclosed. Upon receiving a guest TLB miss exception, a guest OS issues a TLBWE (TLB Write Entry) instruction to logic. The logic runs the TLBWE instruction at a supervisor mode without invoking a hypervisor. The TLB may incorporate entries in a guest page table and entries in a host page table. | 01-03-2013 |
20130142498 | OPTIMIZING RECORDING SPACE IN DIGITAL VIDEO RECORDING OF TELEVISION PROGRAMS CONTAINING COMMERCIALS - Recording television programs for future playback by enabling the user to record a plurality of programs that have sequential units of commercial content. There is sequential sensing for commercial content units. When a commercial content unit is reached, it is removed for separate storage. A determination is made as to whether the removed commercial content unit is the same as a previous commercial content unit that has been removed. Any previous commercial unit that has been removed has been stored in a file and a pointer to the file inserted in place of the commercial in the sequential stream of the television program being recorded. Thus, if the removed commercial unit has the same content, i.e. is a repeat of a previous commercial, the inserted pointer will point to the file of the previous commercial. | 06-06-2013 |

20100031271 | DETECTION OF DUPLICATE MEMORY PAGES ACROSS GUEST OPERATING SYSTEMS ON A SHARED HOST - A hypervisor receives a memory page checksum from a guest operating system, which corresponds to a page of memory utilized by the guest. Next, the hypervisor proceeds through a series of steps to detect that the memory page checksum matches a checksum value included in a checksum entry item, which includes an identifier of a different guest. In turn, the hypervisor shares the page of memory between the guest and the different guest in response to detecting that the memory page checksum matches the checksum value included the checksum entry item. | 02-04-2010 |
20100042996 | UTILIZATION MANAGEMENT - In an illustrative embodiment, a computer implemented method for utilization management is provided. The computer implemented method initiates a utilization monitor to monitor a set of processes, records utilization data for an identified process of the set of processes to form recorded utilization data, and determines whether the recorded utilization data exceeds a utilization threshold. The computer implemented method, responsive to a determination that the recorded utilization data exceeds a utilization threshold, performs an action to manage utilization. | 02-18-2010 |
20100150531 | Method to Improve Storage Efficiency of High Definition Digital Video Recorders - A method and computer program product for improving storage efficiency for a digital video recorder. In one embodiment, a determination is made as to whether television programming is being presented on a high definition channel or a standard definition channel. The television programming is recorded using the digital video recorder responsive to determining that the television programming is being presented on a standard definition channel without making any resolution changes to the television programming. A determination is made as to whether the content of the television programming originates in high definition or standard definition. When the television programming originates in standard definition, a determination is made as to whether a corresponding standard definition channel is available. Responsive to determining the corresponding channel is available, the television programming is recorded in standard definition from the corresponding channel. Otherwise, the television programming is downscaled on the high definition channel to a standard definition resolution. | 06-17-2010 |
20100180158 | Managing Statistical Profile Data - The illustrative embodiments disclose a computer implemented method, apparatus, and computer program product for refining statistical profile data. In one embodiment, the process interrupts an execution of a software program in response to detecting a profiling event during the execution of the software program. The process then records an event sample associated with the profiling event. The event sample is recorded in a log file. The process also inserts a set of markers describing and associated with the event sample into the log file. The process then resumes the execution of the software program. | 07-15-2010 |
