  • Publication number: 20220342679
    Abstract: An approach is disclosed that selects a current processing element from a set of processing elements included in a software pipeline. A selected input data to the current processing element was an output data from a previously executed processing element. The input data is verified by computing a current fingerprint of the selected input data and comparing the computed fingerprint to an expected fingerprint. The expected fingerprint was previously computed after the output data was generated by the previously executed processing element. In response to the comparing revealing that the current fingerprint fails to match the expected fingerprint, a verification error is indicated to a user of the process.

  • Patent number: 8745628
    Abstract: Techniques are presented for managing execution of processes on a data processing system The data processing system comprises process instances that are each an execution of a corresponding process. Each process instance comprises activity instances. Business impacts are determined for the process instances, the activity instances, or both. Order of execution of the activity instances is managed by allocating resources to activity instances in order to achieve an objective defined in terms of the business impacts. In another embodiment, requests are received for the execution of the processes. For a given request, one or more of the operations of assigning, updating, aggregating, and weighting of first business impacts associated with the given request are performed to create second business impacts associated with the given request. Additionally, requests can be modified.

  • Patent number: 8438117
    Abstract: A method and system for managing a service level of a service provided by a service provider to a customer under a service level agreement. The actual measurement data is adjudicated to correct the measurement data in accordance with at least one adjudication element that provides information relating to how to correct the measurement data. The adjudicated measurement data is transformed into operational data by being reorganized into one or more groups of data. The operational data is evaluated by applying a formula to the operational data, resulting in the operational data being configured for being subsequently qualified. The operational data is qualified by comparing the evaluated operational data with specified service level targets for at least one service level period and identifying operational data points meeting and/or not meeting the specified service level targets.

  • Patent number: 8380838
    Abstract: Aspects of the present invention dynamically reduce a frequency at which IT infrastructure automatically generates alerts. Historical data across a plurality of data sources in the IT infrastructure is analyzed. An opportunity to reduce the frequency at which the IT infrastructure automatically generates the alerts is identified. A new alert policy addressing the opportunity to reduce alert frequency is generated. An impact of the new alert policy on a set of predefined service level objectives (SLOs) and service level agreements (SLAs) is evaluated. The new alert policy is deployed in the IT infrastructure.

  • Patent number: 8332267
    Abstract: A method and system for adjudicating measurement data in real time and re-adjudicating a segment of an input measurement data stream upon submission of a new adjudication instruction in a service level evaluation system. An adjudication instruction associated with a service level is received. Measurement data including a first measurement data point is received. The received adjudication instruction is applied in real time to the first measurement data point to generate a first adjudicated measurement data point. A service level is evaluated based on the first adjudicated measurement data point. To re-adjudicate the data stream segment, a new adjudication instruction is received and the segment is identified. The input data stream's adjudication is suspended and the stream is queued into storage. The segment of measurement data is retrieved and re-adjudicated by applying the new adjudication instruction. The input data stream's adjudication is resumed afterwards from the queued input stream.

  • Patent number: 8302097
    Abstract: The present invention relates to the problem of scheduling work for employees and/or other resources in a help desk or similar environment. The employees have different levels of training and availabilities. The jobs, which occur as a result of dynamically occurring events, consist of multiple tasks ordered by chain precedence. Each job and/or task carries with it a penalty which is a step function of the time taken to complete it, the deadlines and penalties having been negotiated as part of one or more service level agreement contracts. The goal is to minimize the total amount of penalties paid. The invention consists of a pair of heuristic schemes for this difficult scheduling problem, one greedy and one randomized. The greedy scheme is used to provide a quick initial solution, while the greedy and randomized schemes are combined in order to think more deeply about particular problem instances.

  • Publication number: 20120066547
    Abstract: A method for problem determination and resolution in an information technology (IT) system includes receiving a problem ticket, searching a database for a plurality of problem features based on data included in the problem ticket, extracting the plurality of problem features from the database, and generating a problem signature corresponding to the problem ticket, wherein the problem signature comprises at least one non-textual feature extracted from the plurality of problem features.
