Abstract: A method includes extending an interface, to a device outside a firewall, for requesting a service performed by a device inside the firewall. The interface is extended using a software component, executing outside the firewall, which executes a separate interface to accept requests for services from devices outside the firewall. The separate interface, exposed outside the firewall, is configured for accepting a subset of the services available inside the firewall.

Abstract: A computer derives, from a current measurement of an attribute of a system, an instantaneous severity score based on a probability model that is determined from prior measurements. The computer then displays, for several successive moments in time, either the instantaneous severity score or an aggregated severity score obtained from a set of instantaneous severity scores (e.g. by averaging). Each set of scores to be aggregated may be identified by, e.g., a fixed-width time window located at a fixed offset from a moment in time at which the aggregated score is to be displayed. Aggregation suppresses or dampens momentary abnormalities, which would otherwise get displayed. In some embodiments, graphs for multiple categories of metrics are displayed on a single screen, aligned in time, to enable a human operator to form a visual correlation therebetween, e.g. to identify causes of atypical performance in the system.

Abstract: An intelligent approach for collecting statistical information in information systems generally involves performing a set of administrative function steps within a “maintenance window” that is defined by one or more specified time periods. First, a set of administrative function steps to be performed are identified. The set of administrative function steps is prioritized to produce a set of prioritized administrative function steps. Then, the set of prioritized administrative function steps is performed during the maintenance window. Aspects and features of the invention include: identifying and prioritizing administrative function steps; estimated function times and maintenance window; failure prediction; environment recommendations; history information and learning techniques; saving state and context information; and user feedback.

Abstract: A method and apparatus for identifying one or more schemas from which a Structured Query Language (SQL) statement may have been executed is provided. According to the method, to identify schemas from which a database command may have been executed a set of object references that are included in the database command is determined. From the set of object references, one or more ambiguous object references that are contained in the set of object references are identified. A set of one or more schemas that contain objects that correspond to each of the one or more ambiguous object references is then identified.
