摘要： A method, system, and computer program product for automatically synchronizing data between a replicated version and a back-end data store version which may or may not have the same format. Queues are used for scheduling refreshes of read-access objects and updates of write-access objects, where the actual processing will occur when the client device connects to the back-end data source. This technique is application-independent, and does not require writing application-specific code to perform a synchronization between data stores having dissimilar storage formats. This technique is particularly advantageous for mobile computing devices, which may operate primarily in a disconnected mode, and for distributed branch-office computing environments where a local server has a replicated copy of data stored at a back-end enterprise system. This technique is also advantageous where the back-end data source uses legacy host application or database storage formats, and where the client software uses modem object-oriented data storage formats. A technique is defined for offloading the processing to a remote machine.

摘要： The present invention provides a method, system, and computer program product for caching objects to improve performance and resource utilization of software applications which interact with a back-end data source, such as a legacy host application and/or legacy host data store or database. Read-only requests for information are satisfied from the cache, avoiding the overhead of a network round-trip and the computing overhead of repeating an interaction with the back-end data source. Refreshes of cached objects and update requests to objects may be queued for delayed processing (for example, at a time when the system is lightly loaded), thereby improving system resource utilization. A sequence of actions that may be required to initiate, and interact with, the refresh and update processes is also preferably stored in the cached objects. This technique is applicant-independent, and may therefore be used for objects having an arbitrary format.

摘要： A method and apparatus for navigating screens in a legacy host system. In a preferred embodiment, requests for specific legacy host screens are received by a server. The server then navigates to the appropriate screen within the legacy host system and retrieves the host screen. Any intermediate screens navigated by the server in reaching the host screen are not displayed to the user. If variable data need be entered to access the host screen, the server sends the user a submittable form on which to enter the appropriate information, which, once entered and sent to the server, is used by the server to retrieve the host screen. Once the host screen has been retrieved, the server formats it into a web page format using a hypertext language and sends the screen to the user. Other screens within the legacy host system are accessed by user selection of selectable links displayed to the user.

摘要： A method, system, and computer program product for caching dynamically generated content (including, but not limited to, dynamically generated Web pages), as well as determining when the cached content should be invalidated or purged. Rather than caching the generated datastream (i.e. the end result of the computations used in the dynamic generation process) as in the prior art, the interim results of computations (such as a generated bean instance or object, where the interim results may be stored using properties and methods) are cached according to the present invention. The input properties used to generate the bean or object, along with the input property values, are used to distinguish among cached instances and thereby identify when a cached instance may be used to respond to a subsequent request for the same content. Re-execution of the business logic of the bean or object may then be avoided, using the cached bean's or object's output properties to generate the content response. Application-specific, developer-defined criteria may be used in the cache invalidation determination.

摘要： The present invention provides a method, system, and computer program product that enables software objects and applications to dynamically self-propagate, as needed, through a computer network. This technique may be used to dynamically establish a mirroring site to which processing of work elements can be offloaded. In addition, this technique can be used to automatically deploy a software application that is comprised of a sender part and a receiver part (such as a client/server application) from a single site without manual intervention. The propagation occurs in an application-independent manner, and may operate symmetrically at either or both the sender and receiver. The life-span of propagated software objects and applications can be specified, in order to control the amount of time the downloaded resources reside on the receiving system. This technique is preferably built on a message queuing architecture, which is particularly advantageous for use when processing requests in an asynchronous execution mode.

摘要： Host interaction and terminal emulation sessions are conducted between a client and a resource by transitioning between terminal emulation states that represent interaction between the client and the resource. Transitions from a present terminal emulation state to a next terminal emulation state is automatically performed based on output provided by the resource and the present terminal emulation state. The terminal emulation may thereby be provided by ScriptUnits XML tags that represent the transitioning of terminal emulation states. The ScriptUnits can be parsed to create an object tree that can be manipulated using a visual editor. The visual editor may be used to change existing states in the terminal emulation session and add new states. The visual manipulation may allow a person who is unfamiliar with source programming languages to support the terminal emulation services. The format of the script representation may allow one vendor to import a script from another vendor to process in the importing vendor's internal structure without affecting the external terminal emulation programs.

摘要： The present invention provides a method, system, computer program product, and method of doing business with automated electronic business (“e-business”) services by using a structured markup language processing engine and structured markup language documents. The structured markup language, which in the preferred embodiment is the Extensible Markup Language (“XML”), is used to describe the data and processing invocations to perform in carrying out e-business services (which may include invocation of a number of sub-services), and to automatically synchronize the interactions that are necessary in carrying out the service. The interactions may involve multiple business partners.

摘要： Methods, systems, computer program products, and methods of doing business by using dynamic capacity-on-demand techniques for re-routing traffic in a distributed computing network. When demand on an enterprise's resources exceeds some predetermined level, dynamic modifications cause static content (such as images) to be served from resources which are external to the enterprise, such as a caching system which is located close to the enterprise's end users. When demand falls below the predetermined level, the modifications are effectively reversed, such that the external resources are no longer used. The predetermined level may apply to a single monitored device, or to a group of monitored devices. The dynamic capacity-on-demand techniques may also be used for dynamic types of content, such as for dynamically re-routing access to an application program executing on an external resource, and may be used for internal capacity-on-demand as well.

摘要： Methods, systems, computer program products, and methods of doing business by caching dynamic content fragments in a distributed cache and assembling requested content using these fragments. The disclosed techniques are non-invasive, and enable the benefits of distributed fragment caching to be extended to more applications, without regard to the programming model used when designing the application. An application developer specifies dependencies among content creating components (or, in alternative embodiments, it may be possible to infer this information), and if one of these components may be called upon to generate a content fragment dynamically, correlator data is programmatically created and attached to a message that references the component. A subsequent content generation request to the component then automatically carries the correlator data, and that data is programmatically restored.
