    摘要: A novel disk drive head stack assembly (HSA) includes a first head gimbal assembly attached to a first actuator arm. A dummy mass is attached to a second actuator arm. The dummy mass includes a mounting plate portion defining a mounting plate width. The mounting plate portion includes first and second projections. The dummy mass also includes a neck portion defining a neck width and a neck length. A root portion of the neck portion is disposed between the first and second projections, and defines first and second alcoves between the root portion and the first and second projections, respectively. The dummy mass also includes a distal mass portion defining a distal mass width and a distal mass length. The neck width is less than the mounting plate width, and the neck width is less than the distal mass width.

    摘要: A mechanism is provided for archiving and restoring transaction files of a database system without requiring the copying of the transaction files. A server system executes a host application that implements the database system comprising a set of database files and a set of transaction files that contains updates to the set of database files, the files being stored in a storage system. A backup engine interacts with the host application to archive a transaction file having an original filename in an original directory by creating a corresponding archive filename to the transaction file in an archive directory. The archive transaction files may be used later to perform a copy-less restore process of the database system that does not require copying of any transaction files. The copy-less restore process restores any altered original filenames by replacing, in the original directory, an altered original filename with its corresponding archive filename.

    摘要: A method and apparatus for providing a distributed service composition model in accordance with the characteristics of an ad hoc network are provided. The method includes confirming whether an adjacent mobile node exists within a number of hops from a task initiator node so as to execute a task, establishing a flow for executing the task with regard to the adjacent mobile node if it is confirmed that the adjacent mobile node exists, and executing the task using a routing algorithm in accordance with the flow. At least one service necessary to execute the task and an execution order between services are determined based on cooperation between adjacent mobile nodes.
