A data processing apparatus and method are provided for performing hazard detection in respect of a series of access requests issued by processing circuitry for handling by one or more slave devices. The series of access requests include one or more write access requests, each write access request specifying a write operation to be performed by an addressed slave device, and each issued write access request being a pending write access request until the write operation has been completed by the addressed slave device. Hazard detection circuitry comprises a pending write access history storage having at least one buffer and at least one counter for keeping a record of each pending write access request. Update circuitry is responsive to receipt of a write access request to be issued by the processing circuitry, to perform an update process to identify that write access request as a pending write access request in one of the buffers, and if the identity of another pending write access request is overwritten by that update process, to increment a count value in one of the counters. On completion of each write access request by the addressed slave device, the update circuitry performs a further update process to remove the record of that completed write access request from the pending write access history storage. Hazard checking circuitry is then responsive to at least a subset of the access requests to be issued by the processing circuitry, to reference the pending write access history storage in order to determine whether a hazard condition occurs. The manner in which the update circuitry uses a combination of buffers and counters to keep a record of each pending write access request provides improved performance with respect to known prior art techniques, without the hardware cost that would be associated with increasing the number of buffers.

A “forward” delta data management technique uses a “sparse” index associated with a delta file to achieve both delta management efficiency and to eliminate read latency while accessing history data. The invention may be implemented advantageously in a data management system that provides real-time data services to data sources associated with a set of application host servers. To facilitate a given data service, a host driver embedded in an application server connects an application and its data to a cluster. The host driver captures real-time data transactions, preferably in the form of an event journal that is provided to the data management system. In particular, the driver functions to translate traditional file / database / block I / O into a continuous, application-aware, output data stream. In an illustrative embodiment, a given application aware data stream is processed through a multi-stage data reduction process to produce a compact data representation from which an “any point-in-time” reconstruction of the original data can be made.

Systems and methods for accessing historical data are provided. Based upon user interaction, a time period of interest and historical data, the systems and methods perform cross-correlation algorithms and interpret which items are to be accessed and displayed to the user via a user interface vis-a-vis a timeline portion and navigation region. Based on frequency and recency usage patterns, and / or user preferences, items are assigned relative weights and displayed accordingly in the timeline portion and navigation region of the user interface. Each item that can be displayed within the system has a unique identification, which may be translated to one or more visual symbols within the user interface. In various non-limiting embodiments, the system leverages a distributed database store which stores and indexes items that make up a digital history. When a request is made to the database, items, such as events, places, people and things, are automatically cross-referenced and correlations are drawn based on filtering criteria.

The object of the present invention is to improve an access efficiency in a distributed environment. When a user “foo” access a file “file_1a” stored in a storage node SN1 under the control of a control node CN1 from a client CLN3 via a control node CN3 as shown by the solid lien arrow in the figure, a record of the access is accumulated in an access history of the control node CN1. If the control node CN1 refers to the access history and detects the frequent accesses from the control node CN3, it replicates or migrates the file “file_1a” to a storage node SN3 controlled by the control node CN3 as shown by the bold line arrow. The replication is performed if another device has accessed the file. Otherwise the migration is performed.

A method and apparatus for authorizing an access requester to access a data communication network is provided. A determination is made that a threshold access control server cannot process an access request associated with the access requester. Access requester history data, or data that describes the access history for an access requester, is analyzed to obtain a threshold access level. A threshold access level is an expression of how likely that a particular access requester is a legitimate access requester. A session profile is selected for the access requester based on the threshold access level. The session profile indicates one or more actions the access requester is authorized to perform in the network. The session profile may subsequently be transmitted to the access requester to allow the access requester access to the network to the extent appropriate in view of the access requester history data.

A system and method for enabling a multiprocessor system employing a memory hierarchy to identify data units or locations being used as software locks. The memory hierarchy comprises a main memory having a plurality of data units, a plurality of caches that operate independently of each other, and at least one coherent domain interfaced to each cache. Each coherent domain comprises at least two processors. The main memory maintains coherency of data among the plurality of caches using a directory that maintains information about each data line. The system of the present invention allows a requesting agent, such as a processor or cache, to request a data unit without specifying the type of ownership, where ownership may be exclusive or shared. The directory includes history information that defines the previous access pattern of the requested data unit. Prior to forwarding the requested data unit to the requesting agent, the main memory checks, using a conditional fetch command, the history information to determine what type of ownership to associate with the requested data unit. The requested data unit is then delivered to the requesting agent with ownership rights specified by the history information. The processors may utilize a directory-based protocol such as MESI (modified, exclusive, shared, invalid) to maintain coherence among the processors, with each processor snooping a shared bus to track the status of caches lines in the other processors.

There is provided a method of efficiently accessing information located on Web pages in a ubiquitous environment such as a home, an office and on a travel. A gateway server is located between a client and Web servers for providing the contents. The gateway server traps a request of a browser operating in the client and records an access history. On the access records, the display form of a link in the contents is changed, and the service of managing the accessed information is presented to the client. Further, the user may optionally set an attribute to the contents and change the display form of the accessed link according to the set attribute.

In a client / server network system, an updated database content is automatically notified from the server computer to all of client computers which have once accessed this database content. In the server computer, an access history record for recording access requests issued from certain client computers is saved in a merchandise information database. When the record of this merchandise information database is changed, the server computer extracts such a client computer which has accessed this database in the past based up on the access history. Then, the server computer notifies a change notification to all of the relevant client computers, so that all of these relevant client computers can recognize the changed database.

A system for providing enhanced history information across multiple clients comprises a call application server having a history system, a telephony system and a history cache. The call application server advantageously maintains a history records for each user of the system. The enhanced history system is particularly advantageous because regardless of the endpoint (e.g., phone, thin client, personal call manager or standalone IP phone) with which the user is interacting, the history information specifically for that user is delivered by the call application server to that endpoint. Furthermore, the call application server allows the user to access history information using end points which heretofore were unable to provide history functionality. Finally, the call application server makes the history records universal across all endpoints with which the user interacts, in contrast to prior art, which had limited call history information specific to a particular endpoint.
