摘要： A connectivity server for a collecting, arranging and representing data defining the interconnection of pages on the World Wide Web (Web). A URL Database stores URLs and associates a fingerprint and CS_id with each URL. The URL Database interface is operable to translate between any two of a URL, a fingerprint, and a Host_id. A Host Database associates a Host_id with each distinct hostname in the URL Database. The Host Database interface is operable to accept a Host_id and return a number equal to the number of URLs on the respective host and to return the CS_ids of those URLs. A Link Database stores links between source URLs and destination URLs. The Link Database interface is operable to retrieve, for a given CS_id, the number of inlinks to and outlinks from the URL corresponding to the CS_id. In an embodiment characterized by a single processor, with access to all databases stored in RAM links and URL information may be retrieved sufficiently rapidly so that applications that touch every link, even multiple times, may execute in real time, in a few minutes or hours. Representative applications enabled by the connectivity server include static ranking of pages (eigenranks), query precomputation, mirror-site detection, and related-page identification.

摘要： A data processing system includes a query progress analyzer. The database processing system comprises a receiver that receives database queries including a target query directed to a database and a query analyzer. The query analyzer is coupled to the receiver and analyzes progress status of the target query based on comparison of measured target query resource usage to resource usage predicted from a query plan of the target query and measured system resource usage.

摘要： According to one embodiment, a method comprises evaluating messages between nodes of a distributed computing environment. Based on timing relationships of the messages, probability of causal links between pairs of messages determined. Based on the determined probability, at least one causal path comprising a plurality of causal links is inferred. Further, an overall probability that the inferred causal path is accurate is determined. In certain embodiments, the overall probability is output for the corresponding causal path to provide an indication of the confidence of the accuracy of such inferred causal path.

摘要： Computer-implemented systems and associated operating methods use atomic query maps to identify and evaluate database query plan robustness landmarks. The computer-implemented system comprises logic that evaluates robustness of a selected atomic query by measuring performance of atomic query execution in a predetermined range of runtime conditions that include data characteristics. The logic produces a set of measurements that can be displayed as one or more performance maps and analyzes the measured performance to identify landmarks indicative of database atomic query performance degradation greater than a predetermined amount.

摘要： An embodiment includes determining user loads and control parameter values. The determining control parameter values are mapped to a performance metric using a function. A constant performance metric is determined where the value of the function calculated at each control parameter value is less than said constant performance metric. An isocontour is defined based on the constant performance metric for each user load. Finally an operating envelope is calculated by correlating the isocontours of multiple user loads.

摘要： A method of performing a multi-way join of a plurality of database relations includes executing a plurality of pipelined two-way joins with the database relations. Each two-way join has two sequential phases. In the first phase, missing attributes of the input relations that are required to evaluate a joining criterion specific to said two-way join are fetched from a non-volatile memory device, and the input relations are joined according to the criterion. In the second phase, any additional missing attributes of the input relations are fetched from the non-volatile memory device as assigned by an optimization process executed prior to commencing the multi-way join.
