Abstract: A method comprises retrieving a change history for each of one or more configuration items for a specified time period, retrieving requests for change identifiers utilized for each of the configuration items in the specified time period, generating an audit report for the configuration items in accordance with the retrieved change history and the retrieve request for change identifiers, determining if each attribute value change in the change history of each of the configuration items is authorized, and recording a marker in the change history through which a given configuration item has authorized changes. Determining if each value change is authorized comprises comparing changes in the retrieved change history to the retrieved request for change identifiers for each of the configuration items to distinguish value changes that occurred without a request for change from value changes that occurred with a request for change.

Abstract: In an economic relationship between a first party and a plurality of second parties in connection with provision of at least one of goods and services for a fee, costs incurred by the first party, in connection with a loss of at least some of the second parties to the relationship, are estimated. A response curve of second party loss probability versus fee is also estimated. An optimal value of a modification to the fee is determined, such that profits of the first party are maximized, taking into account the costs incurred by the first party in connection with the loss of the at least some of the second parties and the response curve of the second party loss probability versus the fee. At least one action to take in response to the determining of the optimal value is determined.

Abstract: Techniques are disclosed for providing cross-tier management in a multi-tier computing system architecture. For example, a method for managing a computing system, wherein the computing system includes a first tier and at least a second tier, wherein the first tier and the second tier are configured to respond to a request received by the computing system, includes the steps of monitoring performance of the second tier from the first tier, and sending one or more management commands from the first tier to the second tier based on the monitored performance. In one embodiment, the first tier may be an application server tier of the computing system, and the second tier may be a database server tier of the computing system.

Abstract: Automated or autonomic techniques for managing deployment of one or more resources in a computing environment based on varying workload levels. The automated techniques may comprise predicting a future workload level based on data associated with the computing environment. Then, an estimation is performed to determine whether a current resource deployment is insufficient, sufficient, or overly sufficient to satisfy the future workload level. Then, one or more actions are caused to be taken when the current resource deployment is estimated to be insufficient or overly sufficient to satisfy the future workload level. Actions may comprise resource provisioning, resource tuning and/or admission control.

Abstract: In one embodiment, functional system elements are added to an autonomic manager to enable automatic online sample interval selection. In another embodiment, a method for determining the sample interval by continually characterizing the system workload behavior includes monitoring the system data and analyzing the degree to which the workload is stationary. This makes the online optimization method less sensitive to system noise and capable of being adapted to handle different workloads. The effectiveness of the autonomic optimizer is thereby improved, making it easier to manage a wide range of systems.
