摘要： 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.

摘要： 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.

摘要： 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.

摘要： A system and method for migrating domains from one physical data processing system to another are provided. With the system and method, domains may be assigned direct access to physical I/O devices but in the case of migration, the I/O devices may be converted to virtual I/O devices without service interruption. At this point, the domain may be migrated without limitation. Upon completion of the migration process, the domain may be converted back to using direct physical access, if available in the new data processing system to which the domain is migrated. Alternatively, the virtualized access to the I/O devices may continue to be used until the domain is migrated back to the original data processing system. Once migration back to the original data processing system is completed, the access may be converted back to direct access with the original physical I/O devices.

摘要： A technique for storing or backing up data to a removable media such as a CD or DVD with an enhanced probability that such data can be successfully read or recovered from such media subsequent to the writing/storing/backing-up of the data. This enhanced probability is achieved by storing the data to be copied to the media in multiple different physical locations of the media, such that a plurality of duplicate copies of the data exists on the media. Because there are multiple copies of the data stored on the media, the probability of being able to successfully read at least one good copy of the data is enhanced. For example, if one of the copies cannot be successfully read due to an unrecoverable error, another of the copies can be used to satisfy the read or restore operation. It is also possible to read all copies of the data in response to a read/restore operation, and any differences in the read data will indicate an error with at least one of the copies. Selection of which copy to select and use to satisfy the read request is based on a vote, where the copies are matched against one another, and the copy having the most matches with other copies is deemed to be the good copy and is used to satisfy the read or restore operation.
摘要翻译：一种用于将数据存储或备份到诸如CD或DVD的可移动介质的技术，其具有在数据的写入/存储/备份之后可以从这样的介质成功地读取或恢复这些数据的可能性增加的概率。这种增强的概率是通过将要被复制的数据存储在介质的多个不同物理位置中而实现的，使得媒体上存在数据的多个副本。由于存储在媒体上的数据有多个副本，所以能够成功读取数据的至少一个好的副本的可能性得到增强。例如，如果其中一个副本由于不可恢复的错误而无法成功读取，则可以使用其他副本来满足读取或还原操作。还可以读取/恢复操作来读取数据的所有副本，并且读取数据中的任何差异将表示至少有一个副本的错误。选择选择和使用以满足读取请求的选择是基于投票，其中副本彼此匹配，并且与其他副本最匹配的副本被认为是好的副本，并用于满足读取或还原操作。

摘要： 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.
