Under the present invention, a request for a Uniform Resource Locator (URL) is received from a client on a server. Upon receipt, a corresponding session object is obtained, and a response identifier is generated. Based on the response identifier, it is determined whether the URL was previously requested by the client. If not, generation of a final response begins. As the response is being generated, a response refresh header is generated and returned to the client with a temporary response. The response refresh header contains a time value for causing the client to automatically send a subsequent request for the URL. After generation of the final response is complete, it is stored in a cache according to the response identifier. Then, when the subsequent request is received from the client, the final response is retrieved from the cache and served to the client.

A rules definition language the authoring rules for concurrent processing. The RDL includes statements that facilitate efficient use of computer resources by allowing a rule to be broken down into one or more instructions, and processing these instructions asynchronously to provide more efficient use of the computer resources. Once processed into the instructions, results thereof can be passed among the instructions to facilitate process completion of the rule.

A method for performing asynchronous statistics updates in a database management system includes receiving a first query against the database, determining if present statistics related to the first query are stale and entering on a queue a request to acquire updated statistics if the present statistics are stale. The queue jobs are executed asynchronously with respect to the query request. As a result, a first query plan may be developed using the present statistics related to the first query. Thus, no delay in processing the query due to statistics updates is incurred. The first query plan may be executed and results given to the requester. At some later time, the request to acquire updated statistics related to the first query is processed asynchronously from the query request. If subsequent queries are received, the queue can delete duplicate requests to update the same statistics. Those subsequent queries can benefit from the updated statistics.

Systems and methods are provided, whereby partitions may become enlightened and discover the presence of a hypervisor. Several techniques of hypervisor discovery are discussed, such as detecting the presence of virtual processor registers (e.g. model specific registers or special-purpose registers) or the presence of virtual hardware devices. Upon discovery, information (code and / or data) may be injected in a partition by the hypervisor, whereby such injection allows the partition to call the hypervisor. Moreover, the hypervisor may present a versioning mechanism that allows the partition to match up the version of the hypervisor to its virtual devices. Next, once code and / or data is injected, calling conventions are established that allow the partition and the hypervisor to communicate, so that the hypervisor may perform some operations on behalf of the partition. Four exemplary calling conventions are considered: restartable instructions, a looping mechanism, shared memory transport, and synchronous or asynchronous processed packets. Last, cancellation mechanisms are considered, whereby partition requests may be cancelled.

The present invention provides a novel technique for Web-based asynchronous processing of synchronous requests. The systems and methods of the present invention utilize a synchronous interface in order to couple with systems that synchronously communicate (e.g., to submit queries and receive results). The interface enables reception of synchronous requests, which are queued and parsed amongst subscribed processing servers within a server farm. Respective servers can serially and / or concurrently process the request and / or portions thereof via a dynamic balancing approach. Such approach distributes the request to servers based on server load, wherein respective portions can be re-allocated as server load changes. Results can be correlated with the request, aggregated, and returned such that it appears to the requester that the request was synchronously serviced. The foregoing mitigates the need for clients to perform client-side aggregation of asynchronous results.

In a traditional application server that uses servlets, when a request is dispatched to a thread the service( ) method of the appropriate servlet is called. When the service( ) method returns the response is sent. This is sub-optimal in the case that an asynchronous event must occur before the response can be sent, because the thread running the servlet must block until the event occurs. The invention provides for asynchronous processing of such requests. In one embodiment, the invention provides an extension to the Servlet API which allows the service( ) method to return (and thus the thread to be freed) before the response is ready to be sent. Then when the asynchronous event later occurs the response may be completed and sent.

This process for maintaining synchronization applies to processors of redundant parallel processing units of a computer running, in parallel and under the control of the same multi-tasking time-sharing operating system (30) and independent clocks of the same speed, with the same applications with the same parameterizations. It consists on the one hand of including in the operating system (30) a synchronization service (303) called by a synchronization interrupt request and applying a correction of synchronization based on comparing the contents of the processed-instruction counters belonging to the various processors (1, 2) and the utilisation of the lockstep operating mode and on the other hand of inserting a synchronization interrupt request when commencing the processing of timing interrupts generated by the scheduler (301) of the operating system in order to terminate a time slice allocated to processing an application. The system calls generated by the applications for the attention of the operating system.

A resource usage analysis tool (23) calculates a number-of-requests variation parameter indicating the variation of the number of processed requests and a resource variation parameter indicating the usage rate and / or variation of the usage amount of the resource of the computer system from a request classification log (31) in which the number of requests processed by the computer system in each measurement period is described and system logs (32 to 34) in which the usage of the resource of the computer system in each of the measurement periods is described. An asynchronous processing detecting module (51) detects at least one occurrence of a post-processing which is a processing to be performed after the return of a response in order for the computer system to process the requests and an unexpected processing which is a processing to be performed independently of the processing of the requests but not to be performed routinely from the number-of-requests variation parameter and the resource variation parameter.

A method, system, and computer program product for efficiently fulfilling java server page (JSP) requests for dynamic web content, in a computer network system. An asynchronous processing (AP) utility pre-defines a number of custom classes to enable the asynchronous processing of requests. A JSP which contains a custom “async:include” tag indicates an asynchronous request for dynamic content. When a set of asynchronous requests are received by an application server, an “AsyncRequestDispatcher” is called to handle the asynchronous processing of each associated request dispatcher include fragment. For each fragment, a separate request thread is initiated. A placeholder corresponding to each “async:include” request is written to a servlet response buffer. HyperText Markup Language (HTML) content, which includes the placeholders, and a number of javascripts are then written to the client browser. The original thread is closed. The Javascripts enable the retrieval of all response fragments which replace the corresponding placeholders.

The order asynchronous processingmethod comprises the steps of receiving an order transaction request sent by front-end equipment, caching the order transaction request to a message queue, and sending a response message to the front-end equipment so as to notify the front-end equipment that the order transaction request is successfully received; reading the order transaction request from the message queue according to a first-in-first-out sequence, and executing a transaction operation corresponding to the order transaction request to obtain a transaction result; and acquiring the transaction result, calling back a uniform resource locator provided by the front-end equipment to return the transaction result back to the front-end equipment so as to notify the front-end equipment that the order transaction request is successfully executed and the corresponding transaction result. The order asynchronous processing method solves the problems that a back-end server in the existing order management system cannot bear highconcurrency of front-end orders and resource waste is generated when the high concurrency of front-end orders is coped through capacity expansion.

A method and arrangement for processing of CCTrCH data in a UMTS system, by: receiving CCTrCH data across a plurality of radio frames and timeslots (310); storing the received CCTrCH data (320); and upon receipt of complete data for a CCTrCH, processing the stored CCTrCH data through channel processing asynchronously to the received timeslot structure (360). Preferably, the received CCTrCH data is stored in a single RAM memory in link-list form, whereby each timeslot of received CCTrCH data can be independently accessed in the memory. This method of buffering the different parts of the received CCTrCH data, so that they can be recombined before the TrCH decoding and de-multiplexing, is both memory efficient and spreads out the processing load over time.

System and methods for asynchronous processing within a web page lifecycle, enabling web page developers to integrate asynchronous work within the web page implementation that can store state inside the page and is applied to requests to the particular page. Handlers initiate event-based or task-based asynchronous operations without keeping a dedicated thread while waiting for a response. The thread is returned to a pool of available threads upon initiation of the process. Results are received on other threads and provided to the page before rendering. Timeout errors are also provided, if a particular result is not received within specified period. The events are delivered in a serial manner so that the page developer uses request instance data without explicit synchronization. This makes a high-scale, asynchronous processing model less complex and more accessible to developers accustomed to web scripting, which is traditionally synchronous.

Improved methods and systems are provided for asynchronously updating forecast rollup numbers. The asynchronousity is achieved by decoupling the source data change from further manipulations of the source data, for example in calculating and updating forecast rollup numbers by user role hierarchy, layer by layer. An event message queue implementation can be used for asynchronous processing. The process works by dequeuing a batch of event messages and then deduping and sorting them before applying forecast logic. Forecast numbers are updated based on target data and then rolled up the user role levels by aggregating forecast numbers for all subordinate forecast data entries.
