Abstract: A method, apparatus, and computer instructions for synchronizing a database used by a client device with at least one server. A locally unique identifier is associated with each record in the database at the client. The locally unique identifier for a deleted record is changed to a selected value. This value is selected in a manner to indicate that a record has been deleted. This locally unique identifier may be a negative value and may be selected by multiplying the locally unique identifier by a negative one. The selected value is used in synchronizing the database and is used to track records deleted since a last synchronization of the database. In the depicted examples, this selected value is unique and allows for mapping back to the locally unique identifier for the record.

Abstract: A GMR sensor is disclosed for sensing magnetically recorded information on a data storage medium. The sensor includes a ferromagnetic free layer and a ferromagnetic pinned layer sandwiching an electrically conductive spacer layer. An in-stack, electrically insulative hard biasing layer is adapted to bias the free layer to a neutral magnetic domain orientation when the sensor is in a quiescent state with no external magnetic fields.

Abstract: A single pole perpendicular write head is provided comprising an inductive write head pole structure comprising a layered structure alternating a plurality of ferromagnetic layers with a plurality of antiparallel coupling layers to form an antiparallel coupled ferromagnetic stack. The antiparallel coupling of the ferromagnetic layers when the head is not writing forms a flux closed magnetic configuration of the write pole resulting in reduction or elimination of stray remanence fields at the pole tip region that may cause unwanted data erasure at the disk surface.

Abstract: The invention relates to a method, apparatus and computer program for reducing the number of data elements checkpointed in a system having at least one data store where operations on said at least one data store are recorded in a log. A point in the log is recorded. The oldest data element in each of the least one data store is determined and it is then determined for each of the at least one data store whether a logged representation of the data store's oldest data element is more recent than the point recorded. Responsive to determining that a data store's logged representation is more recent than the point recorded, it is realised that it is not necessary to force data elements from that data store to disk if the point recorded is made the point of restart for that data store.

Abstract: A system and method autonomically reallocate memory among buffer pools to permit quick access to data. A simulated buffer pool extension (SBPX) is created for each buffer pool in a set of buffer pools. Data victimized from a buffer pool is represented in the associated SBPX. Requests for data that is not resident in a buffer pool but is represented in the associated SBPX are tallied. Periodically, an expected efficiency benefit of increasing the capacity of each buffer pool is determined from the tallies. Memory is reallocated from the buffer pool with the lowest expected efficiency benefit having remaining reallocatable memory to the buffer pool with the highest expected efficiency benefit having remaining reallocatable memory, until either one or both of the buffer pools exhausts its reallocatable memory.

Abstract: A test-program generator capable of implementing a methodology, based on a formal language, for scheduling system-level transactions in generated test programs. A system to be tested may be composed of multiple processors, busses, bus-bridges, shared memories, etc. The scheduling methodology is based on an exploration of scheduling abilities in a hardware system and features a Hierarchical Scheduling Language for specifying transactions and their ordering. Through a grouping hierarchy, which may also be expressed in the form of an equivalent tree, the Hierarchical Scheduling Language combines the ability to stress related logical areas of the system with the possibility of applying high-level scheduling requests. A method for generating testcases based on request-files written in the Hierarchical Scheduling Language is also presented.

Abstract: An SMP symmetrical computer system uses a distributed method for reporting errors in a partitioned system. The computer system uses symmetrical, parallel error reporting registers (ERRs), dynamic logging, and interface isolation. It also supports various error types (eg. severe, transient, recovery) with independent reporting hierarchies. The ERR can be programmed to capture first error, who's on first (WOF), or to accumulate errors.

Abstract: A system and method for delivering asynchronous callbacks from a network server to clients that are unreachable by the network server. The system provides a callback server that receives callback registration requests from clients. The callback server generates a web service based on the description of the service that is being invoked by the client and an associated URL address based on its own address. The network server uses the dynamically generated service accessible at this URL address to deliver the asynchronous callbacks. The callbacks are either delivered to the clients by the callback server, if they are reachable inside the network domain, or made available on the callback server for the clients to poll. In addition, the callback server provides functionality that may be too expensive for the clients to provide locally.

Abstract: A method, device, and program product are provided for streaming a media file over a distributed information system to a client computer running a browser application. First, a server receives a request for a particular media file from the client computer. Then, the server dynamically generates a metafile, whereby said metafile contains information about the identification, location and format of the media file, and returns it back to the client computer. Advantageously, the server intercepts a download request for the actual media file and reinterprets the download request in a request for receiving a corresponding metafile. Thus, instead of returning the requested media file, a metafile is returned that allows immediate streaming of the requested media file without the need of waiting for the download to be finished.
