    摘要： Risks from system architecture evolutions are assessed by an apparatus that comprises a database comprising a plurality of roadmaps for a corresponding plurality of components that may be used to form an enterprise architecture, the roadmaps identifying the planned characteristics of the plurality of components. The apparatus also comprises a modeling module executed by a processor to identify the components that form the enterprise architecture, to identify the current characteristics of those components, and to map those components to the roadmaps for corresponding components among the plurality of components in the database. In addition, the apparatus comprises a risk identification module executed by the processor to identify which of the components that form the enterprise architecture have current characteristics that are different from the corresponding planned characteristics.

    摘要： In a multiple processor transaction processing system, a class response time goal for each class of transactions is enforced by a workload manager, which computes a current average class response time for each transaction class and derives a current class performance index for each of these classes with respect to its class response time goal. Whenever a transaction arrives, the workload manager considers a number of different possible transaction servers to which that arriving transaction could be routed and predicts estimated new values for the class performance indices for each of the considered routing choices. An overall goal satisfaction index is determined for each one and the routing choice corresponding to the best overall goal satisfaction index is selected as the routing choice. In the preferred embodiment, the workload manager also priority rates or orders the classes in accordance with the current class performance indices so that a transaction of a class which is performing more poorly (as judged by its class performance index) gets a higher dispatch priority at the server to which it is routed than a transaction of a class that is performing better.

    摘要： According to one embodiment of the present disclosure, a method for evaluating composite applications through graphical modeling may be provided. The method may include displaying one or more characteristic objects that are graphically associated with a first entity object. An indication of a score calculation methodology of the first entity object and an indication of a score calculation methodology of each characteristic object may be received. A score of each characteristic object may be determined. Each score may be based on at least one or more measurements of a measured object that is graphically associated with the first entity object and the score calculation methodology of the respective characteristic object. A score of the first entity object may be determined and displayed, the determination based on at least each score of the one or more characteristic objects and the score calculation methodology of the first entity object.

    摘要： Failures are detected in servers of a transaction processing system, and transactions are routed to less failure prone servers in the system. Servers in the transaction processing system which are faulty for some transaction classes but good for others are detected, and such servers are used in a judicious manner to maximize the throughput and minimize the response time of the system. Error prone servers are occasionally probed to determine if they have improved in terms of their error characteristics. The mechanism implemented consists of three elements. The first is the selection of a routing algorithm based on the state of the transaction processing system. Second, transactions are used to probe systems considered too faulty for use in order to determine if they have improved in terms of their failure characteristics. Finally, soft ABENDs are detected. The algorithm for transaction routing to detect and control the problem of failing servers in a transaction processing system consists of two parts: The first part routes transactions to servers based on the length of the server queues, the response time of the transactions (i.e., queuing delay plus processing delay), and the perceived failure rate. The second part of the algorithm ensures that error prone servers are not completely ignored. Occasional transactions are used to probe servers in order to determine if they have improved in terms of their error characteristics.

    摘要： Described is a technology by which a system corresponding to a large scale application is built from subsystems that are differentiated from one another based on characteristics of each subsystem. Example characteristics include availability, reliability, redundancy, statefulness and/or performance. Subsystems are matched to known design patterns, based on each subsystem's individual characteristics. Each subsystem's characteristics are associated with that subsystem for subsequent use in operation of the system, e.g., for managing/servicing the subsystem. The known design patterns may be provided in a library, in a programming framework, in conjunction with a development tool, and/or as data associated with one or more operating system services, server systems and/or hosted services that include at least one configuration, policy and or schema. Certain design patterns and/or characteristics patterns may be blocked to prevent their usage.

    摘要： A method for upgrading one of several computer programs stored on an application server in a distributed computing environment while permitting the application server to continue to service requests for other computer programs. In accordance with the method, the application server is prevented from receiving any new requests for the computer program. The system then waits until all current requests serviced by the application server for that computer program have ended. Then, after acknowledging completion of upgrading of the computer program, the application server is permitted to receive any new requests for the computer program. Apparatuses for carrying out the inventive method are provided.
